“ LAB TESTS ARE GREAT. BUT IT’S HIGH-VOLUME PRODUCTION THAT WILL REALLY PUT A SMILE ON MY FACE.I’ve heard some impressive-sounding announcements about recent laboratory successes in

converting my energy into electricity. But to make solar power the global resource it’s capable

of becoming, you’re going to have to expand on those lab results with high volume panel

production. And you’re going to have to deploy those panels on a massive, worldwide scale.

I’m talking gigantic panels. Lots of them. Everywhere. Which is where Applied Materials

comes in. They’ve spent the last 40 years mastering the challenge of taking scientific

breakthroughs and scaling them into commercialized products, at lower and lower prices,

year after year. Now they’re doing for solar panels what they’ve already done for computer

chips and flat panel displays. I mean, they can already deliver 5.7m2 thin film solar panels at

over 8% efficiency in high volume production. Which makes me one happy mid-sized star.”

Not sure about you but I’ll admit that at times I fi nd it easy (at least after some procrastination) to get overly absorbed and caught up in my daily to-do list. Much like running (I’m no pro but enjoy—or, at least, attempt to enjoy—a good run every now and again), sometimes I’m so focused on the end destination, I forget to take in the journey. This is one reason I love my job. Along with the fact the information we provide in this publication relates to bettering the environ-

ment and our future, there are many times I’m forced to stop, reread, and ponder an article or product presented to me. I mean when you consider how perennial rhizomatic grasses (a non-food source) can support biomass power production (see article on page 97), or the global potential of osmotic power (see page 104)—just a couple of examples from this issue alone—it’s quite amazing what projects people are developing.

If you’re ever in need of a break from your daily to-do list and are looking for something to read over and ponder, well, we hope you have our magazine in hand! As I love a good story, I’ve also taken the habit of visiting the site www.ted.com. If you haven’t checked it out before, TED (Technology, Entertainment, and Design) is full of various talks and, by their own description, “ideas worth spreading.” Worth the listen: “William Kamkwamba: How I harnessed the wind.” William talks about how he, at age 14, built a windmill to power his family’s home in poverty stricken

Malawi. I also recommend “Bertrand Piccard's solar-powered adventure.” But, re-ally, there are countless stories; possibly some will add inspiration to your next project or, at the very least, your day.

Of course, conferences and exhibitions are another great place to fi nd not only inspiration, but also valuable, new industry information, products, and services. For a sneak peek at what will be showcased at WINDPOWER 2010, the largest annual wind conference (in Dallas, Texas, this year), fl ip to page 54. There are also show-in-print sections in this issue for the upcoming IEEE PES Transmission and Distribution Conference & Exposition and the International BIOMASS Conference & Expo.

In addition, we focus on distributed energy storage, the smart grid, and on the fi -nancing of renewables. After all, for alternative energy to fully succeed, it eventually comes down to an ability to fund projects from start to fi nish and an ability to store renewable power for use on-demand. There was an interesting study presented in “Scientifi c American” (November 2009) that evaluated a quantitative plan for pow-ering the world solely on wind, solar, and hydro energy—proving that it was not only possible but, ultimately, cheaper than sticking with fossil fuels or going nuclear. The key to making the plan work? Commitment. (Not to mention new infrastruc-ture, transmission grids, etc…but, it is possible.) Seems like one journey worth see-ing through.

Enjoy the read! Michelle Froese

Smart Grid web portal IEEE recently launched Smart Grid Web Portal, an integrated gateway to Smart Grid intelligence, education, and news. The Web portal is designed for manufac-turers, policymakers, educators, academics, governments, engineers, computer scientists, researchers, and other stakeholders in the power and energy, information technology (IT), and communications industries.

The term Smart Grid refers to the next-generation, managed electrical power system that leverages increased use of communications and information technology in the generation, delivery, and consumption of electrical energy. It is a revolution-ary undertaking, entailing new capabilities for communications and control, inte-gration of new energy sources, distributed generation, and adoption of a regulatory structure. The IEEE Smart Grid Web Portal is designed to be an essential resource for anyone involved in Smart Grid—whatever their industry or technical discipline.IEEE Smart Grid | http://smartgrid.ieee.org | www.ieee.org

Mapping the ocean fl oorThe new book “Ocean Globe” (ESRI Press) examines bathymetry from its early history through today’s use of geographic information systems (GIS) and other technologies to map the ocean fl oor. With contributions from oceanographers, explorers, and historians, this new book is a valuable resource for those interested in coastal management, seafl oor mapping, and marine biology. The anthology ad-dresses how recent developments in bathymetry and seafl oor mapping are applied to animal migrations, coral reef growth, tsunami forecasts, coastal ecosystems, aquatic farming, whale habitats, and more. The book also explains how advances in technology and mapping in a server-based GIS environment enable the improved collaboration and sharing of methods and data.ESRI Press | www.esri.com/esripress


7North American Clean Energy

In February, I had the privilege of chairing a panel of wind energy chief executive offi cers at the American

Council on Renewable Energy RETECH 2010 conference in Washington, DC. The panelists were Eddie O’Connor, CEO of Mainstream Renewable Power, a European de-veloper engaged in offshore and onshore wind (and com-mencing activities in the States); Peter Duprey, CEO of Acciona North America, a European owned wind and solar developer in the US; Paul Gaynor, CEO of First Wind, a private equity backed wind developer in North America; John Langdon, CEO of Viryd a small wind technology company; and Bruce Bailey, CEO of AWS Truewind, a well-known engineering and consulting fi rm.

Given the conference was in Washington, the discus-sion focused on policy and regulation. Two headline issues for these chief executive offi cers were: 1. the need for im-proved incentive programs for wind and other renewable energy projects; and, 2. the need for improved transmis-sion and grid integration regulation.

Eddie O’Connor laid the groundwork with a compari-son of the European incentive programs. Major European wind nations have provided cash-based incentives such as the German feed-in tariff or the UK renewable energy certifi cate regime. Peter Duprey highlighted the feed-in tariff transmission and permitting regime in Ontario as be-

ing a good North American model. The advantage of the feed-in tariff is in its simplicity: wind projects are paid a set price in cash for production (which may vary offshore versus onshore). Wind, therefore, is not taking the risk of fossil fuel cost variability (i.e. being competitive in high, natural gas price periods and less competitive in low-price periods), nor is the subsidy hidden and potentially skewed as with tax based incentives. The feed-in tariff is very fi -nanceable with a broad range of sources and has proven to permit the use of a high level of low cost debt—making the overall cost of project capital cheaper.

The US federal incentive system is largely tax based, using production or investment tax credits, as well as accelerated depreciation. Though the incentives are benefi cial, they can only be used by developers that are large, public companies with US tax liabilities. The tax equity market developed to monetize tax benefi ts for all the other developers that cannot use them. These developers are both large, non-US com-panies, as well as smaller, US-based developers. In those tax equity transactions, wind developers sell interests in renew-able energy projects to investors with the price, taking into account the value of the tax benefi ts allocated to the inves-tor. United States tax rules restrict the use of tax benefi ts to large, tax paying companies and, within that universe, not all companies are interested in the energy sector. As a practical matter, the tax equity market has been limited to fi nancial institutions, life insurance companies, and utilities. Because of the relatively limited number of investors, the cost of tax equity is relatively expensive when compared to debt, and the transactions are relatively expensive to document.

The fi nancial crisis in the US signifi cantly reduced the amount of tax equity. Concern over the inability to fi nance renewable energy projects was in part addressed by Sec-tion 1603 of the American Recovery and Reinvestment Act of 2009. Section 1603 permits a wind project devel-oper to elect to receive a Treasury grant for 30% of eligi-ble costs in lieu of an investment tax credit or production tax credit. This program has resulted in over $2.4 billion being paid to renewable energy projects. But, the program is only available for projects commencing construction by the end of 2010. The question then is: what’s next? The tax equity market is still not fully recovered. Congress is being asked to consider an extension of the grant. Con-gressman Earl Blumenauer, together with cosponsors from the House Committee on Ways and Means recently introduced H.R. 4599, the “Renewable Energy Expansion Act of 2010.” Under this bill, the Treasury grant would be replaced by a refundable investment tax credit that would apply to projects commencing construction in 2011 and 2012, and include a number of features applicable to the Section 1603 grant program. The RETECH panelists expressed concern over the changing terms of, and poten-tial delay in extending, the incentive program. The result of delay may be that developers will be compelled to ac-celerate projects in 2010 that might otherwise have been

brought to construction in the following year. This out-come might be good for jobs in 2010, but this approach will increase costs given the impact of accelerated demand on equipment, people, and capital.

In summary, the US historically has used tax-based in-centives for renewables. That approach was changed in light of the fi nancial crisis. A period of uncertainty is ap-proaching where the current grant program may expire or be subject to extension. The chief executive offi cers emphasized the need for consistent and long-term incen-tive policies with a preference for cash-based incentives. Changing the rules every year does not work. But there is a hope that in the next year or so there will be the op-portunity for improvement in the federal incentive regime. Though a feed-in tariff might be preferred to a tax-based incentive system, such a system at the federal level has yet to gain legislative traction. On the other hand, a national renewable portfolio standard, which should result in re-newables pricing competitively against similar technology (over time resulting in pricing that is not fossil fuel based), is a possibility, as it was included in the Waxman Markey bill passed in the House and versions of the Senate energy bills proposed last year. A national RPS and a phase out of tax incentives should result in the longer term with power purchase agreement pricing correlated to renewable energy production costs (including cost of capital), which pricing would provide a fi nanceable cash fl ow stream simi-lar to a feed-in tariff.

Transmission was a theme running through all the presentations. Bruce Bailey summarized the results of the

NREL Eastern Wind Integration and Transmission Study (EWITS), published in January 2010. The study examined the feasibility of penetration of 20% to 30% of wind in the Eastern Interconnect—approximately 225,000 to 330,000 MW of wind. The conclusions included that wind integra-tion at that level was feasible, but transmission investment was key. The ability to bring wind from the western part of the Eastern Interconnect, as well as from offshore installa-tions, would mean that a high penetration of wind would be feasible and include the benefi ts of geographic diversity of wind resources. The study indicated a high penetration of wind might include a cost of intermittency of about $5/mWh (but as one speaker noted this might be set off against the value of wind as a hedge against fossil fuel vola-tility, not to mention greenhouse gas reduction).

The challenge of transmission is that it is diffi cult to license, expensive, and politically charged. It takes much longer to plan and build a transmission project than it does to do the same for wind farms. Trans-state or regional transmission lines face even more complicated permitting and political hurdles. As a consequence, wind farms get built but are curtailed (as has been the case in West Texas), or they cannot obtain fi nancing because of the curtailment risk. To achieve 20% wind by 2030, the federal government needs to act as decisively as it did with the National High-way System, and treat national transmission development as a national priority and not a matter of local convenience.

The development of interconnection policy will aid both large- and small-wind projects. Permitting and intercon-nection rules and costs remain a challenge to the growth of distributed generation, as well as utility scale projects. The clear goal for the wind industry is to support a coher-ent national policy on transmission siting and permitting, including federal licensing with the power of eminent do-main. Add federal funding and guarantees, and the country will see transmission construction proceed at a record pace. However, industry leaders are also aware of the com-plicated politics around transmission, and recognize that the desired goals may not be politically achievable.

The panel concluded with a question on the oppor-tunities for offshore wind in the US. The EWITS study includes an aggressive case with up to 79 GW of offshore wind. The developers on the panel were not especially op-timistic about offshore wind given the strong onshore re-sources and markedly lower costs of construction. But, the development of the best onshore resources depends on the ability to access load centers, and one’s assessment of the likelihood, timing, and cost of major national transmission development. The competitiveness of offshore wind very much depends on the assumptions made about the ability to construct a transmission superhighway, and to deal with congestion into load centers in the Northeast specifi cally. To the extent that national transmission policy does not evolve, and transmission is not built, then the window for offshore wind may be open. Although this might not be the view taken by this panel of executives, the continued development of projects by Cape Wind, Bluewater, and others tells us there is another point of view.

wind energy

The reliable matching of power supply and load is the cornerstone of electric grid operations: the electricity supplied must match the amount withdrawn.

The problem, though, is that by their nature, the variable energy resources (VER) that are increasingly being added to the grid—principally wind and solar projects—are not subject to direct control. Therefore, their addition raises operational issues (albeit ones that can be solved) about how best to match or balance these relatively new sources of supply with load.

This was the question posed by the Federal Energy Regulatory Commission (FERC) in its January 21st, 2010 Notice of Inquiry on Integration of Variable En-ergy Resources, and it’s one that can be answered in several ways. But one answer is to facilitate the widespread deployment of energy storage technologies and, spe-cifi cally, utility scale Distributed Energy Storage (DES). Last century, it was a fun-damental precept that electricity could not economically be stored to any material degree, but this is no longer the case. Today, if the energy anticipated to come from a variable resource turns out not to be available in real time (because the wind isn’t blowing or the sun isn’t shining), stored energy can be substituted. Simply put, we have at our disposal storage devices that draw electric power from the grid during off-peak periods and, then later when the power is needed, are discharged to pro-vide back-up energy typically at a lower cost than the energy that otherwise would have been withdrawn to backup the VER—assuming this energy was even available during the times of peak demand. These same devices, when operating in charging mode, can also provide ancillary services by reducing the level of demand during periods of the day when VER and load are ramping up or down.

Utility scale DES consists of hundreds, thousands, or hundreds of thousands of energy storage devices located at residential, commercial, governmental, and/or in-dustrial sites. What makes “utility” scale DES possible is that it can be electrically aggregated in the form of thousands of individually sited, small storage devices, and then linked through the Internet, or other electronic means, to the System Control and Data Acquisition (SCADA) systems used by the electric grid operators. An opera-tor can then control and dispatch the aggregated storage devices as though they were actually a single 50 or 100 megawatt (MW) generator or load that could be shed.

In short, utility scale DES would not only allow large amounts of load to be seamlessly shifted from high-cost peak hours to low-cost non-peak hours, but would also provide a way to store the power from VER that otherwise might need to be curtailed. The DES devices, by reducing their demand, can also provide balancing service when needed to fi ll in at such times as the VER might fl uctuate beyond grid tolerances, be this over the course of a few seconds or minutes, or from hour to hour, or over the course of a day. In so doing, the DES would make the VER considerably more valuable and more plentiful.

But, is this really true? Isn’t meaningful energy storage via electric and hybrid electric vehicles years away? Yes, but fl ywheel systems that provide rapid ramping for regulation service are already deployed in the PJM Interconnection and in the New York ISO, and are under development elsewhere. Plus, utility scale DES in the form of aggregated and centrally controlled ice storage air conditioning is now a reality. In January, the Southern California Public Power Authority (SCPPA), a group of 11 southern California municipal utilities, announced it had entered into a long-term agreement with Ice Energy, Inc., a Colorado-based fi rm, to purchase and deploy thousands of Ice Energy’s storage devices at small- and medium-sized commercial and government buildings in the SCPPA utilities’ service territories. The devices, which are installed next to fi ve- to 20-ton air conditioners, make ice at night and at other non-peak hours, usually when wind power both is plentiful and

cheap. During daytime peak load hours, the ice is used to cool the refrigerant and to air condition the buildings. Collectively, the devices, which will be “cycled,” will be aggregated and centrally controlled by the member utilities, be used to shift 53 MW of peak-load to off-peak hours, and be available to provide ramping serv-ices during the early morning and evening transition periods when load, net of wind (referred to as “net load”), is ramping up or down.

From the perspective of wind power producers, DES, particularly on the scale available from DES suppliers such as Ice Energy, provides numerous types of “partnering” opportunities to fi rm or backup the capacity of wind and other VER generators, particularly through the energy, ancillary services, and capacity markets administered in RTO and ISO markets—where, coincidentally, most of this power is being developed. However, because the current markets were developed prima-rily to accommodate the operating characteristics of large, central station plants rather than VER and utility scale DES, certain adjustments to these markets would be needed to make these partnering opportunities a reality. In its Notice of Intent, FERC recognized that certain of the market rules might not be fl exible enough and, therefore, might need to be modifi ed to level the playing fi eld for VER and those new technologies that would aid VER integration. In particular, FERC sug-gested the expected large increases in VER will require increases in the amount of reserves and it sought ways to reduce the need for, and cost of, such reserves.

Here are several suggested market rule changes that would facilitate DES’s ability to fi rm up VER when necessary, and to increase the value of both:

1. Provide a market revenue stream for the system effi ciency value and other ben-efi ts resulting from peak load shifting such as lower peak-hour prices, increases in capacity factors, and reductions in curtailments, transmission congestion, and line losses.

2. Create a new category of Load Following Reserves. Obviously, load following service would be more available if its providers were compensated. Utility scale DES could be dispatched for load following if limited offers and operation were permitted.

3. Allow combined, partial day, Day-Ahead Market offers or, alternatively, create an intra-day Real-Time Market. DES participation in the day-ahead markets is constrained because it can’t be offered in all hours. Allowing partial day DES and VER offers to be combined would eliminate real-time deviations and increase supply source participation.

4. Allow combined Forward Capacity Market offers from VER and DES resources. VER participation in forward capacity markets is limited to the capacity avail-able during peak load hours. Although current markets allow summer and winter seasonal resources to be combined, it is not permissible for different resources to be combined during the same season. Allowing combined VER and DES offers would allow VER capacity to be “fi rmed.”

In sum, there is no one or two silver bullets here. But, given its obvious potential, system operators should take all economically justifi ed steps to fully integrate VER and technologies like DES into the power markets.

Vibration acceptance levels for wind turbinesWind turbines, by reason of their design, location of installation, and operation, do not abide by any international stand-ard for vibration. To increase reliability, uptime, and operation of wind turbines, the Association of German Engineers, Verein Deutscher Ingenieure (VDI), in collaboration with manufacturers, such as PRUEFTECHNIK Condition Moni-toring, LUDECA’s principals, helped in developing the VDI 3834 vibration and evaluation standard for wind power plants. The VDI 3834 standard will help to close the gap between this and other well-established standards for threshold values of specifi c components. This means that vibration signals of wind power tur-bines are no longer a problem to measure and evaluate when using a vibration ana-lyzer such as VIBXPERT and its OMNI-TREND PC software, which both feature built-in VDI measurement standards.

Reaching Wind Grid Parity Energy Not just about

initial cost per wattBy John Skibinski

wind energy

Today, more than 85% of the wind energy production cost

is the initial capital and installa-tion. Operations and maintenance (O&M) accounts for about 15% of the total energy production cost. But, though initial capital costs fall only a few percent per year, owners are watching O&M costs rapidly increase after the fourth year—where O&M costs can grow to more than 20% of the total en-ergy production cost.

For instance, an American Wind Energy Association (AWEA) O&M Council sur-vey identifi ed the following electrical issues…

Early failure of electrical components Less than ideal matching of the generator and converter results in damage to the converter from generator power transients. In addition, IEC power converters are not designed to be robust enough for the US grid, which exhibits far more severe power transients than Europe’s grid, and so IEC power converters fail earlier than expected. And, like IEC power converters, IEC contactors and breakers are de-signed for up to 105% over-current—a level far less than the frequent power tran-sients of the US grid. In a comparison test by a major US wind turbine OEM, UL/ANSI components outlasted IEC components by about 2.5 times when subjected to US grid conditions.

In addition, interviews on behalf of American Electric Technologies, Inc. with various wind farm operators identifi ed the following electrical issues…• Less than expected electrical system performance at start-up and across the life

cycle. • Lack of complete electrical systems integration between IEC turbine systems and

the ANSI electrical collection, substation, and yard systems, resulting in less than desirable electrical system coordination that impacts start-up performances.

• Lack of integrated life cycle operations and maintenance planning, which allows use of electrical equipment from different suppliers that, because of different design objectives, results in non-optimized electrical design and integration that underperforms over the life cycle.

Getting down to grid parity production costs requires a better approach to manag-ing O&M costs over the life cycle. Many of the following O&M costs are over-looked and often under-estimated during the planning stage of a wind farm. But, over time, they add up to impact the total wind energy production cost to the detri-ment of the return on investment of the farm.

• Installation: reducing costs that arise from inadequate commissioning by inexpe-rienced contractors.

• Operating: reducing costs resulting from early failure of non-UL conversion and protection equipment from power surges.

• Maintenance: reducing revenue loss from unplanned system failure.• Replacement: reducing costs due to using shorter life IEC rather than UL &

ANSI electrical components.

Containing costs: End-to-end electrical integration To truly contain O&M costs over time, it is important to integrate and implement the turbine and balance of system equipment using one electrical systems supplier.

Two goals are attained by this approach:1. Optimized electrical design and project costs. Although initial costs are

slightly higher, farm ROI is improved by specifi cation of third-party certifi ed components (UL, KEMA, etc.) that last longer than self-certifi ed (IEC) compo-nents for US wind farms. Electrical coordination is also improved when using the same equipment supplier who utilizes the same brand of third-party certi-fi ed components in their electrical equipment design. And, by using an electrical systems supplier with construction experience, farm ROI is further improved by eliminating the layers of subcontracting and implementing end-to-end systems engineering visibility into the construction of the electrical power infrastructure from generation to grid.

2. Reduced electrical operations and maintenance costs. Although the start-up costs are higher, farm ROI is improved by utilizing a third party to validate farm construction against the design to obtain end assurance that the farm was installed, coordinated, and commissioned correctly while the contractors are still on the development site. Then, by implementing a condition-based monitoring solution, combined with an early warning preventative maintenance service, the complete approach results in the highest improvement in farm ROI an owner/operator can obtain today.

To get down to grid parity production costs, an end-to-end integrated approach to-ward managing electrical O&M costs over the life cycle is not only essential during O&M, but during the design, build, and construction phases.

This includes:• Integrated UL/ANSI bundling of equipment into NEMA 3R line-ups or contain-

erized solutions that are pad-mount ready wires in & out package. This reduces installation costs by deploying pre-wired, pre-tested, and pre-commissioned UL and ANSI equipment at the site.

• Using one supplier experienced with IEC, UL, & ANSI power conversion and switchgear, which results in coordinated equipment that performs longer with less revenue downtime.

• Using a supplier capable of integrating complete remote condition monitoring in conjunction with providing preventative maintenance services to provide early warning of a failure. This results in minimal revenue loss when the system is serv-iced, long before a drastic electrical failure occurs.

• Replacing IEC components with UL and ANSI upgrades so that longer electri-cal operating life can be achieved. And, by using a supplier that can also refurbish IEC, UL, & ANSI power components, the costs of using new IEC components to repair portions of the wind power infrastructure is avoided.

As initial capital costs continue to decline, attention will turn toward using one sup-plier to integrate wind turbine conversion and wind farm collection subsystems, substation, and electrical yard subsystems as custom and complete packages. As a result, the value adding supplier of tomorrow is an integrator of electrical systems end-to-end for both wind turbine and wind farm electrical systems, which includes the design, installation, maintenance, and refurbishment of the equipment and con-struction of the farm—all under one extended agreement.

We can take wind turbines to new heights.


At its root, the concept of clean energy by way of wind power is a simple one. Wind power is

the conversion of wind energy into a useful form of energy such as mechanical power or electricity. Wind energy is a clean fuel source, in so far as that wind power plants don’t contribute to air pollution like other forms of energy plants that rely on the com-bustion of fossil fuels such as coal. Since wind power plants don’t produce emissions that cause greenhouse gases and wind is not in short supply, energy experts see wind energy as a viable alternative source to more conventional, non-renewable sources like oil.

The logistics of transporting the equipment used to make wind power work—wind turbines—can, however, be anything but clean and simple. The mas-sive size of wind turbine parts presents challenges in their transportation. A single turbine can require up to eight hauls (one nacelle, one hub, three blades, and three tower sections). According to the American Wind Energy Association, over 5,000 wind turbines were installed in 2008, resulting in approximately 40,000 transportation hauls.

Each customer has different characteristics regard-ing the control of their supply chain. Some want to handle the logistics from origin to destination. This includes all tier suppliers and fi nished products. Oth-ers look for turnkey management. Giving wind farm logistics over to a single source who will handle the international, domestic, and fi nished product logistics allows a reduced investment in headcount. The turn-key also includes port management and wind farm site management working hand-in-hand with their customers and multi-mode suppliers.

The tower sections used in wind power can weigh more than 150,000 pounds, be 120 feet long, and 15 feet in diameter. The blades can range in size from 127 feet to 140 feet. Like hauling anything else of such large size, moving wind energy parts requires more diligence on the part of everyone involved. The coordination of such a move is very unique. There are numerous issues that can handicap routes, including:

• clearance, height, width, and weight issues; • poor road conditions; • permitting; • coordination with state and municipal authorities;

and, • differing laws and regulations per state/

municipality.

The movement of wind blades 140 feet in length re-quires an experienced driver and escorts. Specialized equipment is needed to transport the parts associated with wind power. The blades must be transported us-ing custom-made stretch trailers specifi cally designed to haul wind power blades. The wind tower sections are hauled on specialized 13-axle Schnabel trailers, which, when loaded, are stretched out to 200 feet in length, are over 15 feet in height, and width and gross 230,000 pounds.

Coordination with local and state authorities is critical to determine whether special arrangements need to be made regarding time of transport, the moving of utilities, police escort, etc. It is not uncom-mon for a wind turbine move to require more than double the miles of a given route’s usual point A-to-B distance due to various laws that require alternate routes. Diffi culties arise when the freight must travel through multiple states, which have differing regula-tions regarding specialized freight. Matching state permit entries to former state exit points can also cause delays. Route surveys must be detailed to refl ect the height restrictions on each route, as well as exit and entry turning radiuses. This is not a simple proc-ess. A great deal of pre-planning makes this possible.

A qualifi ed, experienced pilot car is critical in mitigating the risks involved in such a move. Careful planning on behalf of the dispatcher and driver must be taken to ensure a safe, timely, and cost-effective transport. States have been very good at working with carriers to help defi ne routes. However, possible wind energy transport standards that defi ne routes and support the weight complications could further smooth out the process. Ultimately, as the supply chain continues to shorten, the complications will be reduced.

The conditions of the delivery site also play a key factor. Wind farms are usually located in rural areas, which often do not have the infrastructure (i.e. roads) to properly accommodate such specialized freight. Drivers often fi nd themselves delivering to a destina-tion with unprepared dirt roads, which depending on site or weather conditions, can create a hazard. Chal-lenging turns and grades also pose diffi culties.

Ultimately, experience and preparation on the part of the logistics provider and truck operator will best ensure a successful delivery.

Arecent study presented at the last European Wind Energy Conference iden-tifi ed the importance of housing and planet carrier fl exibility on the reliabil-

ity of wind turbine gearboxes and bearings. The fi ndings suggested that industry design standards should demand consideration of fl exible support structures to en-courage more reliable wind turbine drivetrains.

Reliability of wind turbines is widely acknowledged as a key issue, specifi cally with regard to the wind turbine’s gearbox. The gearbox is a sub-system where fail-ures are common, costly, and poorly understood. There is a need for engineers to examine the standard processes for wind turbine gearbox design, better understand the parameters infl uencing reliability and to, ultimately, improve the standard.

In the study, it was identifi ed that design standards do not explicitly recommend the consideration of gearbox housing or planet carrier fl exibility in the design process. If a gearbox failure occurs (though it is not the most likely component to fail), forensic analysis of the components allows designers to understand the failure mode and the root cause behind the failure. This is undertaken using a combination of expert knowl-edge and specialist software simulation tools to provide detailed gearbox analysis.

Virtual product development and simulation tools for gearboxes, drivetrains, and bearings allows the generation of detailed gearbox and driven models that incor-porate all major component interactions and fl exibilities. A single, fully coupled analysis can include non-linear bearing and gear contact models, shaft defl ections, gearbox housing deformations, as well as interactions with the nacelle bedplate and gearbox mounts.

Four gearbox and drivetrain models of differing complexity were created for this study. All models included fl exible shafts and accurate representations of the gears including detailed gear contact models and mesh stiffness. The simplest of the four models included simple bearing models with linear stiffness and no clearance, as well as a rigid planet carrier and no housing fl exibility. The second model was simi-lar, but all of the bearings were replaced by non-linear bearing models incorporat-ing fl exible raceways, clearances, and detailed contact mechanics. The third model was more detailed again, this time including a fl exible planet carrier and the de-tailed, non-linear bearing models. The fi nal model was fully detailed and included fl exible housing, as well as the non-linear bearings and fl exible planet carrier.

The four gearbox models were ana-lyzed under a simulated load of 100% torque and simulated rotor weight acting on the main shaft and the mis-alignment of each gear mesh was cal-culated—high misalignment between meshing gears being a major contribu-tor to poor gear life.

Analysis results clearly showed the calculated gear mesh misalignments de-pended strongly on the amount of detail and fl exibility in the gearbox model, and results identifi ed that the simplest model predicts a good tooth load distribution (e.g. the load is fairly centred on the tooth and well distributed), but the fully detailed model predicts a poor contact pattern with high edge loading. These results indicated that without taking into account the effects of fl exible support structures, engineers can incorrectly estimate gear life, potentially leading to gearbox failures later in the fi eld.

As a result of the study, it is suggested that new wind turbine standards should recommend the consideration of gear-box housing or planet carrier fl exibility in the design process, as well as encour-age the use of accurate simulation tools upfront in the design stage—so as to lead to a greater understanding of sys-tem behavior and reliability in design.

As more companies in the alternative power industry examine ways to improve productivity and safety, a trend is emerging where choices for overhead

lifting devices aim toward complete systems supplied by a single manufacturer or distributor, rather than obtaining individual components from a variety of sources. Whether it is part of a lean manufacturing initiative to increase productivity dur-ing the manufacturing of blades, shafts, or related components, or where individual work cells result from an overall production process change, more fi rms are relying on the experience of industry experts to secure systems that meet specifi c require-ments. Crane builders, material handling specialists, and manufacturers are concen-trating on offerings that address all concerns from fl oor to ceiling. By taking this approach, much of the guesswork about compatibility of components is removed from the process and the user can be confi dent that the system satisfactorily meets all needs.

In addition to examining systems as part of the manufacturing process, more fi rms are looking for ways to incorporate everything from integral beams to slings in the turbine to assist with lifting needs related to maintenance activities. Hoists

A Complete Product Mix for Lifting & Maintenance

in the Wind Power

IndustryBy Rob Beightol

are mounted in the nacelle or tower and used to effectively lift parts and tools needed for regular maintenance work. Long lifts and fast lifting speeds are required in this environment, as is the ability to effectively hold the excess chain of the hoist. Some manufacturers provide heavy duty hoists that feature lifting speeds in excess of 60 feet/20 meters per minute with custom chain containers designed specifi cally for the requirements of the wind industry.

Though a beam/hoist confi guration has traditionally been viewed as a “system,” more attention is being paid to additional items that act as vital parts of a complete overhead lifting system. Depending on the job, a beam/hoist system may be all that is needed to perform the job safely and productively. However, for many applica-tions, the selection of proper below-the-hook lifting devices such as slings, shackles, and custom attachments is vital to match the system to the job. There are a number of choices available to the user including chain, wire rope, and synthetic slings, hooks, hoist rings, and tongs. Deciding which product to use for the job is based on a number of factors including the type of material being lifted, the size or bulk of the load, lifting angles, etc.

In addition to a complete lifting system that provides secure lifts throughout the turbine, many users are also looking for tools that directly assist with maintenance activities. One of the primary choices for this are lever tools that may be used to lift, position, or pull components or parts that are important to the overall maintenance of the generating system. These lever tools are offered in an array of styles and ca-pacities, from heavy duty designs with long handles and automatic braking systems to compact styles that are perfect for confi ned areas.

Since so many variables exist in selecting the proper hoist and rigging products for the job, most users consistently seek training programs that address these vari-ables. In many cases, this training is included as part of the package purchase and can range from “lunchbox” sessions where items such as pre-inspection procedures, hand signals, wear tolerances, and the like may be covered. More in-depth programs that deal with ASME and OSHA regulations, full teardown and inspection of hoists, visual inspection of chain and wire rope are available through many manufacturers and independent training fi rms. One of the most important trends in the industry today is the focus on comprehensive training that deals with all aspects of overhead lifting. Some training fi rms and manufacturers offer “train the trainer” programs that allow a worker or group of workers to attend intense classes on proper lifting and rigging. These workers in turn act as the experts on the jobsite and pass on their knowledge to the workforce through meetings and tests. Additionally, some manufacturers offer certifi cation programs that allow participants training sessions and pass a series of tests to offi cially become certifi ed on a line of products.

The collective goal of manufacturers, distributors, and users is to focus on a safe, productive working environment. By selecting complete overhead lifting systems based on the exact needs of the job and maintaining a comprehensive training pro-gram, all parties are taking steps toward this goal.

Preventing turbine generator failureBy safely channeling harmful shaft currents away from bearings to ground, Electro Static Technology’s new AEGIS WTG wind turbine grounding ring prevents bearing damage that could otherwise cause generator failure, unplanned downtime, costly re-pairs, and lost revenues. Maintenance-free, effective at any RPM, and available for any size wind turbine generator, the ring is designed for OEM installation or easy up-tower retrofi t.

High-frequency currents induced on the shafts of wind turbine generators can reach levels of 60 amps and 1200 volts or greater. If not diverted, these currents will discharge through the generator’s bearings, causing severe electrical damage that results in bearing failure and catastrophic turbine failure, sometimes in as little as six months or less. The AEGIS WTG’s patented conductive microfi ber technology effectively steers these currents away from the bearings and safely to ground. The WTG is engineered to safely divert up to 120 amps of continuous shaft current at frequencies as high as 13.5 MHz and discharge up to 3000 volts (peak). Ideal for use as part of a preventive maintenance program to protect against premature bearing failures, it can be installed whenever bearings are replaced.Electro Static Technology | www.est-aegis.com

In an effort to fi ll a budget shortfall that has now grown to $2.8 billion, the 2010 Washington State Legislature has proposed eliminating the sales and use tax ex-emptions for machinery and equipment used in renewable energy projects other than wind energy projects. However, the proposal would also severely curtail the exemptions for wind energy projects, allowing the exemption for only projects

Small-scale wind support systemNRG Systems, manufacturer of wind measurement equipment for the global wind energy industry, has introduced a 34-meter system to support small-scale wind energy projects and wind energy research. With more incentives for small and community scale wind, there is a greater need for people to understand their wind resource before investing in a turbine. This 34-meter complete system includes a tubular tilt-up tower, a Sym-phoniePLUS 15-channel data logger, three NRG #40C anemometers, a wind vane, and parts. Easily installed and port-able, the system can be used for micro-siting or prospecting applications, or in remote locations where installation of taller towers may not be possible.NRG Systems | www.nrgsystems.com

Bill Curtails Sales Tax Exemption for Renewable Energy Projects And potentially discriminates against wind energy

owned or used by local utilities, or projects of which the electricity is sold, to lo-cal utilities.

Last year, the 2009 Legislature substantially revised the Washington sales and use tax exemptions applicable to the purchase of components and installation services that are used in projects that use wind power to generate electricity (see RCW 82.08.962; RCW 82.12.962). Pursuant to the 2009 law, for the period from July 1st, 2009 through June 30th, 2011, a 100% sales and use tax exemp-tion is available. For the period from July 1st, 2011 through June 30th, 2013, a 75% sales and use tax exemption is available. The 2010 Legislature proposes to eliminate those exemptions altogether for non-wind energy projects including solar, biomass, geothermal, and other projects. For wind energy projects, the ex-emptions would be available only if the project will be sold to or used by a local electric utility, or sold to or used by a person that sells the resulting electricity to a local electrical utility. The effective date of these proposed changes is not clear, but the amendments seem to be intended to apply starting July 1st, 2010.

These amendments to RCW 82.08.962 and RCW 82.12.962 were fi rst pro-posed in Senate Bill 6763 on January 25th, 2010. Now, they have been incorpo-rated into the Senate’s omnibus tax bill, Senate Bill 6873, as sections 2501 and 2502. SB 6873 was fi rst submitted to the Senate on February 24th, 2010 and was the subject of public hearings on that same day. The Commerce Clause of the United States Constitution (Art. I, § 8, cl. 3) forbids state taxes that discriminate against interstate commerce in favor of local commerce. Complete Auto Tran-sit, Inc. v. Brady, 430 U.S. 274 (1977). As the Supreme Court explained: “Our Commerce Clause jurisprudence is not so rigid as to be controlled by the form by which a State erects barriers to commerce… ‘The commerce clause forbids discrimination, whether forthright or ingenious. In each case, it is our duty to determine whether the statute under attack, whatever its name may be, will in its practical operation work discrimination against interstate commerce.’” West Lynn Creamery, Inc. v. Healy, 512 U.S. 186, 201 (1994) (quoting Best & Co. v. Maxwell, 311 U.S. 454, 455-56 (1940)). For this reason, the limitation on wind energy projects in the proposed legislation is likely unconstitutional.

Although the constitutional infi rmity was pointed out to the Senate during February 24th Senate committee hearings, SB 6873 remains a live bill. Statements in the record indicated a concern with meeting the current budget defi cit, even if the courts would later order tax refunds for all wind projects in the future. If SB 6873 is enacted, affected taxpayers may wish to bring immediate lawsuits against the state, seeking restraining orders against collection of sales and use taxes with respect to wind energy projects. Although taxpayers are normally required to pay all contested taxes before seeking judicial relief, RCW 82.32.150 provides an exception for taxes that appear to be in violation of the United States Constitution.

Modular design wind power systems Nordex SE will soon be unveiling the third generation of its 2.5 MW turbine series: the Gamma generation. Comprising the N80, N90, and N100 wind power systems, this effi ciency class combines the latest research and development with technical know-how and experience from a decade of producing and operating multi-megawatt turbines to meet today’s market requirements. In the development of the Gamma generation, Nordex has remained true to proven principles, using tested series engineering and as-signing top priority to the dependability of all system components. The N80/2500, N90/2500, and N100/2500 turbines are based on a common technical platform.

A consistent modular design allows Nordex to add type-specifi c components and customer options. This modular concept and the maximum component weight of 50 tonnes makes it possible to transport turbines to anywhere in the world, and speed up both installation and service of the machines. Nordex has redesigned the nacelle, hub, and rotor blades in the new generation to be both lighter and more robust. This also simplifi es transportation and installation, while simultaneously reducing the static and dynamic loads on the overall turbine.Nordex SE | www.nordex-online.com

Laminator for producing long composite wind partsThe new Flat Charge Laminator (FCL) from MAG Industrial Automation Systems is ideal for automated, high-production lay-up of composite spars, beams, stringers, and similar parts for wind-blade manufacture. The highly repeatable system drastically reduces labor while improving part quality, productivity, and consistency. With four heads dedicated to four different materials, the servo-controlled machine produces constant- or variable-thickness laminates on a segmented vacuum table, compacting the layers with a force of 13.6kg to 136kg (30lbs to 300lbs). The FCL handles 0/90 prepreg fabric, +/- 45 prepreg fabric, unidirectional tape and, as an option, foil or fi lm. Maximum material width is 300mm (12 inches) on rolls up to 635mm (25 inches) diameter and weighing up to (150 pounds).

The machine also features four servo-controlled dispensing heads on a placement carriage that moves on rails integrated with the vacuum bed. The servo-powered placement carriage is driven by rack-and-pinion system. A Siemens PLC precisely controls the entire process with speed and position feedback from rotary and linear encod-ers on dispensing heads and placement carriage. The servo-driven supply reels are protected with a magnetic clutch override, and the backing paper take-up system is torque controlled. A stylus cutter cuts prepreg at 90°, without cut-ting the backing paper. MAG | www.mag-ias.com



solar energy

Utility scale solar is poised to fulfi ll its promise as a key renewable power source on the North American grid, but there are some signifi cant technical

and economic challenges to be resolved. Partnerships between the government and industry are being formed to remove the barriers. For example, the SEGIS program (Solar Energy Grid Integration System) was created in 2008 by the US Department of Energy and Sandia National Laboratories as part of the Solar America Initiative (SAI). SEGIS funds critical R&D that targets the specifi c challenges of integrating increasingly large amounts of photovoltaic (PV) power generation into the current and future grid, while becoming increasingly cost-competitive with conventional forms of electricity.

Now in the second phase of this $24M program, fi ve teams across the US are working on various aspects of the project. The major developments of the team (which are led by PV Powered) can be grouped into two main categories:

1. Technologies to improve the economics of solar power and increase the energy harvest of solar systems;

2. Technologies that will help solar power plants integrate more effectively with the utility grid.

Improving solar energy economicsTo achieve widespread adoption of solar power, PV power plants of all sizes must maxi-mize energy production while, at the same time, be highly reliable, economical to oper-ate, and easy to install and service. High reliability is a fundamental requirement of PV power systems that are expected to return a positive return on investment (ROI), but solar power installations impose harsh environmental stresses on system components.

Typically, the places that have the most sun also have the highest temperatures, as well as the widest daily temperature fl uctuations—factors that are very hard on electrical components. Also, unlike other centralized power plants (e.g. fossil fuels, hydroelectric), distributed solar power system elements are typically exposed to the outside environment, with extremes of humidity, dust, corrosives, and precipitation that can act on system elements to reduce their productive lifetimes. Improving the environmental hardening of system components, as well as developing effective preventive maintenance regimens to minimize system downtimes, requires sophisticated modeling of system and environmental behavior.

However, maximizing the energy harvest of a solar power system goes beyond simply keeping it working. The PV Powered SEGIS team is also working on making solar sys-tems more effi cient. Maximum power point tracking (MPPT) is the process of varying voltage and current delivered by a solar array to maximize the energy harvested as the array output changes. As the power conversion effi ciency of an inverter approaches the theoretical maximum, the accuracy and effectiveness of the MPPT algorithm processed by the inverter becomes one of the few remaining variables to be optimized in deliver-ing maximum energy harvest. The SEGIS team is developing a test plan for quantifying MPPT effi ciencies under dynamic conditions using a range of solar array technologies including the new thin-fi lm arrays (see Figure 1). The team is also researching how better forecasting of irradiance can be used by inverters to smooth out fl uctuations in the power that the utility sees.

Improving integration of solar plants with the gridAs the number of utility scale solar plants in North America continues to rise some new, complex problems are emerging that require partnering between utilities and component hardware and software vendors. The work includes the development of new standards for maintaining two-way communications between solar plants and utilities, and the design of new methods for coordinating solar systems’ handling of grid fl uctuations and interruptions.

To develop means for improved communications and control between solar plants and utilities, for example, PV Powered and its SEGIS team member Portland General Elec-tric (PGE) are working to establish two-way communications between PV power plants and PGE’s GenOnSys distributed resource command and control system (see Figure 2). This will enable the utility to disconnect PV systems remotely if needed and receive sta-tus and assert control commands if necessary.

SEGIS work is also directed at developing an advanced method to detect unintentional islanding conditions, a condition where the PV system is producing power into a utility grid that is experiencing an outage. PV Powered is collaborating with Schweitzer Engi-neering, SENSUS, and PGE on a technique that will enable the inverter to differentiate between a true utility outage (where the inverter needs to disconnect from the grid), and

a grid disturbance in which power support from the PV system could assist in providing stability. The solution be-ing explored by the team involves relating two or more phase measurements (called syncrophasor measurements) of the power signal, taken at different locations around the grid, according to the same absolute time base. With this information, the inverter can distinguish between a true unintentional island case and a case where grid support from the PV plant is benefi cial.

Partnerships are keyAlong with improving reliability and energy harvest at the component level, for utility scale installations it is essen-tial to examine the performance of the system as a whole. Collaboration between “balance of system” (BoS) vendors as part of the SEGIS program will enable better system management and increase overall energy production at an acceptable cost, which are top priorities of the US Govern-ment in bringing the players together.

With the problems solved, or at least substantially on the way to solution, solar power can assume its rightful place as a critical large-scale component of our nation’s renewable energy portfolio.

Globally, countries are increasingly looking at responsible, sustainable ways to meet their electricity demands. Power from the sun and wind is free, abundant, and can

be scaled to provide large amounts of energy with zero emissions. However, as larger projects are developed and more renewable energy is brought online, the impact could challenge the operations of today’s grid if not properly managed.

As the power electronics technology required to bring energy generated into the grid evolves, renewable energy power plants will have the opportunity to enhance the stabil-ity of the grid rather than compromise it. Current wind technology has matured so that a wind farm can operate similarly to a conventional power plant. By adapting wind tech-nology to solar, solar inverters—an important link in a system—can offer highly reliable power conversion in multi-megawatt projects.

Wind energy: “Lessons learned”The wind industry is more advanced than solar in terms of understanding how variable, renewable power sources can best be integrated into the grid. Both wind and solar rely on variable resources to generate power, however, wind power electronics technology has

evolved to reduce the impact of the resource variability on the grid. By understanding the challenges and the lessons learned from the wind industry, solar technology can better respond to intermittency.

Historically, as wind power plants increased in size and penetration, transmission faults that resulted from short voltage sags became signifi cant system events. In these cases, larger wind farms meant that an increased amount of wind generation was disconnected when a turbine’s fault threshold was too low. The inability of wind farms to ride-through grid disturbances reduced the operability and stability of the grid.

Both wind technology and wind-related grid codes have since evolved to meet these challenges. Today’s codes require that wind turbines have low-voltage ride-through, volt-age regulation, as well as other functionality to ensure the energy generated by wind tur-bines contributes to the stability and reliability of grid operations. To meet the evolving grid codes, power electronics technology has played a critical role by providing functions such as low-voltage and high-voltage ride-through without additional turbine cost.

Impacts of large-scale solar on today’s gridTwo key differences in solar and wind generation are the type of variability and the way the energy is distributed. In the case of solar, energy generated is directly proportional to insolation—or incident solar radiation—so it varies over time. These variances can be predictable (the sun’s location in the sky according to the time of day) and/or random (as when a cloud passes by). In terms of distribution, large-scale utility solar projects generally involve many more distributed generation sources as compared to traditional centralized power generation systems. In the past, small-scale distributed generation had often been added on to the existing grid with little consideration of how they might be optimally integrated into the power system. Generally, smaller residential and commer-cial projects minimally impact the grid; however, with an increase in the number of utility scale projects, the variability of solar power, if not properly managed, can impact the sta-bility and reliability of the grid.

Large-scale solar projects are being measured by two key metrics: power conversion effi ciency and reliability, and so advanced grid integration technologies will be critical for the success of utility scale solar. Power conversion effi ciency refers to how much energy is retained when converting from Direct Current (DC) to Alternating Current (AC). Reliability refers to the ability of a PV system to deliver power when solar resources are available. A solar plant’s inverter is the fundamental power block within the system and delivers grid integration functions that range from low- and high-voltage ride-through to monitoring and control.

Solar inverters: Solutions for solar integrationSimilar to the inverter in a solar plant, a wind turbine relies on a robust power electronics package called a converter to transmit power generated by the turbine to the grid. It is in the turbine’s converter that the majority of the technology required to meet grid codes exists. In a solar power plant, the inverter is able to provide similar capabilities.

For example, GE’s solar inverter (designed for use in multi-megawatt projects) is based on the proven wind turbine converter design currently employed in its 13,500 wind tur-bines operating worldwide. Though grid codes for solar power plants do not yet require the same ride-through and power regulation today, it is only a matter of time before this is the case. The GE inverter has been designed with the expectation that the capabilities now required in wind will very soon be required for solar. For instance, it can:• aid in maintaining voltage level under varying loads;• provide reactive power for voltage support;• support the grid during disturbances; • enable power curtailment control based on needs of the grid, and,• reduce power during over-frequency events.As with wind, grid codes will have to evolve to best support the adoption of growing solar resources into the grid. Ultimately, grid integration capabilities will help to coordinate the operation of distributed inverters and utility equipment, resulting in signifi cant addi-tional system benefi ts at low incremental costs for grid operations and increase the value of solar plants for owners and operators.

Next-Generation PV System& Grid Management By Sjuli Beekhuis

Past & present: solar monitoring & managementBefore 2005, a PV system owner had to go onsite and look at a meter to determine if their system was feeding energy to the grid. Remote monitoring capabilities included cus-

tom hardware and software packages designed for a specifi c site—often too costly and too compli-cated for the average residential PV system owner to easily get value from them. Onsite maintenance was usually a yearly check of the inverter to ensure if it was running properly and, perhaps, a cleaning of the modules if they appeared soiled.

With the spread of the Internet and home com-puters, many inverter companies offer some type of near real-time, web-based monitoring for PV systems and some installers offer a monitoring package that allows a system owner the ability to remotely check on its status. In other industries, there are signifi cantly more sensors and data from the system than what a typical PV system moni-toring package provides. The ability to monitor and control systems is available through current technologies; it has simply not been applied to PV systems because of the small number of systems installed and lack of standards that would apply to all sizes of systems.

The US Department of Energy (DOE) states the following in their vision statement about the future of PV power plants in the US*:

Solar Energy Grid Integration Systems (SEGIS) concept will be key to achieving high penetration of photovoltaic (PV) systems into the utility grid. Advanced, integrated inverter/controllers will be the enabling technology to maximize the benefi ts of resi-dential and commercial solar energy systems, both to the systems owners and to the utility distribution network as a whole. The value of the energy pro-vided by these solar systems will increase through ad-vanced communication interfaces and controls while the reliability of electrical service, both for solar and non-solar customers, will also increase. The US Department of Energy (DOE) is spend-

ing millions on grants to achieve this vision and new technologies for advanced communications and controls are being developed and brought to market through their support.

Advances in automated management An exciting development in hardware technology is the “smart” PV module—electronics on the PV panel or in the junction box that sense the voltage, current, and temperature of each module and send

that data to a central processor. Examples of new capabilities include dynamic power point track-ing at the module level, automatic safety detection (such as arc fault prevention), night-time theft monitoring, and real-time grid response. Smart PV modules can infl uence the MPP (Maximum Power Point) of each panel and create more power output from each module in the string. Data from existing systems show that even well-matched strings of modules can have voltage output differences due to panel aging, differences in temperature, and soiling or wiring issues, which can create a difference of up to 15% in voltage output of a string). The sub-optimal modules drag down the rest of the string and can cause noticeable power losses.

Safety & theft prevention Electronics on the module can detect problems be-fore they cause a catastrophic event. For example, if there is an arc fault on a module, the system can detect it, shut down the module automatically, alert

the system operator to the problem, and pinpoint the specifi c module having the issue. This can also be ap-plied to thermal over-stress from hot-spots, as well as show a bypass diode malfunctioning. An additional use for the two-way communication technology is to monitor the connections of the modules in the PV ar-ray for theft protection. For remote sites, this can be a signifi cant savings in security and insurance costs.

Advanced performance modeling With the system reporting power and environ-mental data at one-second intervals, it simplifi es the ability to model performance predictions based on specifi c module and regional attributes. This not only allows for the system to develop heuristics to provide alerts if it is not performing as expected, but also allows for use of the best practices in de-sign of future systems under similar conditions.

Control of energy fl ows: grid response The use of real-time system analytics, along with control of PV arrays, can minimize impacts to grid power disruptions by re-routing power through backup energy sources. If the grid goes down and a control system is in place, there is the opportunity to re-route the power produced to a battery stor-

age bank or to an isolated sub-panel for emergency operations while the grid is down, making best use of the energy produced by the PV array. Control of distributed resources also allows for peak load shifting and shaving when the solar resource (and demand) is at its highest. This can result in increased peak load offset and additional savings on energy bills.

Intelligent operation: system-aided control By approaching long-term system main-tenance with more insight and analysis, operators can lower the costs and time spent while increasing the effectiveness and timeliness of their actions. At com-missioning, module-level debug data can be a valuable tool to check that the en-tire system is operating as expected. If a PV module is not operating within spec, the problem can be spotted through the software. A look at a management console can pinpoint the underperform-ing module. An advanced management system can also show which modules might benefi t from cleaning, and send a report stating when the optimal time for maintenance should be scheduled.

SafetyIn a traditional PV array, when the sun is shining, the DC voltage of a string can run from 375 V to 600 V in the US, and up to 1000V in utility scale and European applications. With the ability to control each module, an operator can disconnect the string of modules or the entire array onsite or through software to increase safety at the PV array.

With the support of the US DOE, system operators, integrators, and Power Purchase Agreement fi nanciers, bids on new PV installations will require active management to maximize kWh output and system safety. As electron-ics on the module become available as a standard feature, systems from resi-dential through utility scale will have the advanced management, and control commonly found in other advanced systems such as computer networks and other energy systems.

Around the world, manufacturers of solar power systems (solar technology/solar tracking systems) must cope with the same problems—the search for

robust drive systems. A highly precise and effi cient drive system for long-term maintenance-free service and a high degree of reliability is key to a successful system. Only drive components produced exclusively for outdoor use meet these requirements and allow maximum user benefi t.

The gear unit componentsIn solar technology, it is generally recommended to use a worm gear unit for azi-muth adjustment of a tracker. By target-adjusted selection of defi ned materials, required parameters such as perfect wear behavior, high-fatigue strength, and long-term corrosion protection can be achieved and implemented. Exceptionally slow movement is achieved by using a high-reduction ratio. Within the drive system, the static self-locking that occurs is a positive side effect. This is a feature of worm gear units that prevents the drive from being operated out of an idle state caused by an external infl uence (such as wind) from the panel surface. The gear motor’s internal brake guarantees pin-point selection of the tracker position, even under the infl u-ence of possible vibration.

Sunny countries are fortunate to use solar power stations. However, they must fulfi ll the requirements for extreme environmental conditions such as temperature, humidity, as well as the saline and dust concentration in the air. All contact surfaces exposed to direct environmental infl uence must be covered with a special coating or increased corrosion protection. In combination with special sealing elements, the grease used for this purpose guarantees a working range at extreme temperatures between –20 °C and +70 °C (–4°F and 158°F).

The motor componentIn addition to a fi rm supporting structure, developers of solar tracking systems attach particular importance to the selection of the drive for azimuth adjustment. Reasons for this are related to the central function of the exact orientation of solar modules according to the controls setting and the costs for acquisition, operation, and maintenance. A robust gear unit motor with enclosure protection IP 54 or IP 65 is used as the drive. The task of this drive, in combination with a control unit, is to align the solar modules for the optimum position to the sun. No additional mounting parts are required to achieve the required enclosure protection. Instead, the components are integrated into the drive unit motor. This way, costly sealing measures are unnecessary and, furthermore, the weak points of conventional drive unit systems are minimized. In addition to increased dirt contamination resistance, the drive unit will withstand extreme weather conditions and still provide full performance in spite of ambient temperatures between –20 °C and +70 °C (–4°F and 158°F).

Further important parameters can be defi ned via the motor components. In ad-dition to the integral brake and depending on the tracking system, a transmitter can be selected as a feedback system. The transmitter is also fi tted within the motor housing and, therefore, meets the requirements necessary to resist extreme environ-mental conditions. This not only allows pre-setting of the exact position of the solar modules, but also allows checking and correcting of the actual position feedback. At the same time, the driving behavior of the complete tracking system is pre-defi ned due to correct selection of the motor with suitable controls. The desired drive pro-fi les such as acceleration and deceleration ramps, as well as the ideal rpm range for achieving the various operation speeds at the required torques can be defi ned.

Success through teamworkThe differences in driving accuracy requirements are: from several degrees of posi-tion accuracy deviation for conventional tracking systems (i.e. the system has to be adapted to the sun position every 10 to 15 minutes), to highly effi cient solar systems equipped with concentrator modules. These solar modules continuously track the sun position, and the focal point is adjusted to the optimum position as the sun moves across the sky.

A drive system virtually free from backlash must be chosen to fulfi ll these requirements. When combining the gear unit and motor, major attention is paid

Using special gearing technology, a circumferential backlash of almost “zero” can be achieved. In combination with the high-resolution transmitter system of the drive and the positional fi xing using the integral brake, sustainable improvements in the effi ciency of solar power systems with concentrator modules or within the Heliostat sector can be achieved.

ConclusionThe main criteria for selecting a drive system for solar applications are its robustness, cost factor, and ease-of-operation. Selection of individual components and lubricants used should guarantee maintenance-free operation for 20 years. Last but not least, the cost for acquisition, opera-tion, and maintenance of solar power systems should not neutralize the increase in effi ciency and the benefi ts gained due to tracking. The com-plete system, as described, will ensure higher accuracy for increased power generation. It does not merely form the basis for further use of renewable energy but, even more important, renders solar power competitive for the future.

Energy Storage:The Holy Grail for renewable

energy & the Smart GridBy John Battaglini

As the Smart Grid continues to develop and integrates more

renewable energy sources, energy storage will represent a key value proposition for the electricity grid of the future. Solar and wind will certainly pose challenges to the grid as more of these intermittent energy sources come online. Moreover, with the future adoption of plug-in vehicles, smart energy management will be needed to assure the quality and reliability of the grid. To this end, energy storage systems will serve as a key foundation technology that will advance the grid to its full potential.

According to the Energy Storage Council, the Department of Energy (DOE) estimated in 1993 that energy storage could have a $57.2 billion positive impact from the widespread use of “high-density storage devices to…store power during off-peak periods and deliver it when loads exceed generating capacity.” The Council has since updated this forecast to $175 billion over the next 15 years. Interestingly, Japan and Europe far outpace the US in energy storage with 15% and 10%, respectively. The US falls way behind with just 2.5%. Needles to say, the States is playing catch up, but not for long.

Putting energy storage to the testRecently, utilities and system integrators in the US have initiated several demonstration pilot programs to prove the viability of energy storage and its potential impact on the grid. Besides grid stabilization and load leveling, storage systems can potentially provide back-up power to thousands of residential and commercial customers, especially when solar or wind is not available. As more renewable energy sources are integrated into the grid, managing and storing energy is essential due to the intermittent nature of these renewable sources.

Another key driver for energy storage is the renewable portfolio standard (RPS), adopted by states to signifi cantly increase the amount of electricity generated by renewables. According to the DOE, as of May 2009, there are 24 states plus the District of Columbia that have RPS policies in place. Together, these states account for more than half of the electricity sales in the United States. The state of Maine has an aggressive goal of 40% by year 2017.

Imagine BIG Possibilities.The ISYS Ground Mount solution is the fi rst modular framing system utilizing modern techniques for large scale utility and commercial projects. Designed to deliver the most cost effective system, the ISYS Ground Mount has a total installed cost as low as $0.40 per watt with an industry leading installation rate of more than 10 modules per man-hour.

California wants to reach 33% by 2030, and many other states want to reach between 15% and 20% in the next fi ve years and beyond.

Bringing storage closer to the consumerA future outcome of the Smart Grid is Community Energy Storage (CES). Coined by utility, American Electric Power, CES is part of the utility’s gridSMART demonstration project. This project, funded in part by $75 million DOE stimulus funding, will be deployed to 110,000 AEP customers in northeast central Ohio. The idea is to provide the utility and its customers many benefi ts including load leveling, back-up power, support for plug-in electric car deployment, as well as grid regulation and improved distribution line effi ciencies.

As part of this fi rst-of-its-kind project, AEP and system integrator, S&C will test large format lithium ion batteries (Li-Ion). Different from their smaller cousins used in fl ashlights and IPods, large format lithium ion prismatic batteries (see Figure 1) provide the right-size building blocks to deliver higher amounts of energy and scale up as energy demands increase. Of course, controlling and understanding the state of the batteries is vital, and that’s where highly intelligent battery management comes in to play. Using state-of-the-art software and electronics, today’s advanced battery monitoring systems can tell users the exact state of the battery, state of health charging status, and temperature.

Figure 1. Large format lithium ion prismatic battery.

Another interesting project utilizing energy storage has been deployed in Maui, Hawaii. With electricity rates the highest in the country, the

Maui Economic Development Board wanted to assess the effectiveness of storing solar energy using effi cient battery technology. The renewable energy system is comprised of sixty 224-watt photovoltaic panels, a bi-

directional three-phase inverter system, and a state-of-the-art charge-controller network provided by HNU Energy in Maui. A 48V, 16.4kWh lithium-ion based energy storage system was integrated—complete with

battery management and controls—to store the energy generated from the solar array.

The energy storage system includes four battery modules, totaling 32 160Ah lithium iron phosphate (LFP)

Active system management for PV projectsThe Tigo Energy Maximizer Solu-tion begins with small, reliable elec-tronics on each module that enable module-level power point tracking for up to 20% more energy output. The system also captures module level output data to feed an advanced analysis engine. This automated software enables real-time module level performance views, sends alerts for system faults or module theft, and guides targeted maintenance actions. The net result is informed, active management, which minimizes O&M costs while keeping the system running at peak performance. Ad-ditional control capabilities include the Tigo Energy PV-Safe Feature for arc detection, thermal overstress, and shutdown in case of maintenance or fi re emergency. Compliant with relevant UL, CE, and FCC require-ments, and CEC listed, the Tigo Energy Maximizer Solution is a cost-effective addition to existing or new utility scale, commercial, or residen-tial projects.

cells and a battery management system (BMS) that is integrated into a standard 19" portable rack mount chassis and enclosure (see Figure 2). As with the CES project, large-format lithium ion batteries were chosen because of their proven high-energy density, robust thermal, and cycling performance, as well as easy system expandability.

Necessity driving innovationAs electric vehicles and the Smart Grid transform their respective industries, the role and signifi cance of energy

storage will continue to increase. And, while there are different storage solutions such as fl ywheels, compressed air, and hydro, as well as various battery technologies, large format lithium ion cells are leading the way in many high-energy applications due to their near 100% effi ciency, scalability, and versatility. It is interesting to note that the energy storage market made huge strides during the course of 2009. So much so in fact, that of the $185 million granted from the DOE for 16 projects, $83.1 million went to 11 battery related projects. From

an economic and environmentally sustainable perspective, the future looks very bright for energy storage.

Solar tracking systems PV installations and tracking systems are now being constructed on increas-ingly diffi cult substrates—for example, on former farmland or decommissioned landfi lls. DEGERenergie has developed solutions for anchoring its systems se-curely in place. The operational safety of solar tracking systems is a matter of how fi rmly the system is attached to the substrate. The standard solution, using concrete foundations, is suited to a secure system installation in any substrate. That involves the foundation being permanent-ly installed above ground or sunk into the ground with the mast anchored in the concrete foundation. To help with a fu-ture dismantling of the systems, eye hooks may be affi xed to the concrete founda-tions. In cases where local building laws don’t permit concrete foundations, the systems with drill or screw foundations are recommended. Screw foundations are equipped with a spiral at the lower end, which is then screwed into the substrate.DEGERenergie | www.degerenergie.com

Internal temperature sensor for solar collectorsSolar Skies Mfg., manufacturer of solar thermal collectors, is now offering an option to maximize the effi ciency of their solar collectors.

Crystalline module for metal roofsSOLON presents the fi rst crystalline module that can be attached to metal roofs using an adhesive. The frameless design of the SO-LON Black 280/12 module is attached directly to the roof using a silicone-based adhesive—without any roof penetration. This way, there is generally no need for an assembly system. Assembly time is substantially less when compared to a conventional solar power system using crystalline modules because fewer components are required and installation is uncomplicated when using an adhesive. The SOLON Black 280/12 is manufactured using 72 monocrystalline cells and weighs only 8.5 kg/m, making it extremely lightweight. This feat is made possible by eliminating the frame and using 3.2 mm of glass. The connection socket is rotated by 180° to facilitate assembly and improve cable routing. The modules are particularly well-protected against theft since they are attached with an adhesive. It is also protected against corrosion with other foreign materials on the roofs.SOLON | www.solon.com

investing in clean energy

The fi nancial crisis spawned two major stimulus pack-ages in the US that have reshaped the federal policy

landscape for renewable power. Most notably, qualify-ing solar, wind, and other renewable energy generation projects can choose either a 30% investment tax credit (“ITC”), or a 30% cash grant in lieu of the ITC (so-called “section 1603 grants”). Wind and other non-solar projects formerly eligible only for the production tax credit (“PTC”) can, for a limited time, elect any of the PTC, the ITC or the cash grant. To qualify for the cash grant, projects must be operational (placed in service) by the end of 2010, or else must begin construction by then and be placed in service by the end of 2012 for wind, and by the end of 2016 for solar.

A fairly simple statute and online application process has made the cash grant program a success. As of this writing, the Department of Treasury has paid or allocated over $2 billion in cash grants. Most of the money has gone to large-scale wind projects that had been completed or were “shovel ready” when the program opened in July 2009. Many solar projects, including commercial and mu-nicipal distributed generation, have also benefi ted from this program. Treasury has not published detailed formal written guidance addressing technical questions arising under the program. Much of the guidance has been anec-dotal; comments made by IRS offi cials at conferences, re-ports of comments made, or positions taken by the IRS in the applications process. In January, however, The Treas-

ury Department released “Frequently Asked Questions and Answers” (“FAQs”), providing supplemental guidance under the cash grant program.

Tax-exempt entitiesThe most signifi cant FAQs relate to tax-exempt entities including schools, colleges, charitable organizations, state and local governments and agencies, and some foreign persons. These entities are not typically owners of energy projects and could not benefi t from the ITC if they owned the project. The FAQs confi rm that tax-exempt owners of projects are not eligible for the cash grant. The ITC is also not allowed for a project owned by one party and leased to a tax-exempt entity; however, if the tax-exempt merely purchases the power generated by the project un-der a power purchase agreement (“PPA”), then the owner may claim the ITC. For this reason, many fi nancings of distributed generation projects with municipal or other tax-exempt customers are structured as PPAs, rather than as leases. Under a common structure, a third-party tax equity investor is the owner of the project under a sale-leaseback with the developer-lessee, who in turn sells the power to the tax-exempt customer under a PPA.

In a signifi cant variation from the ITC rules, the FAQ provides that the cash grant is available to the owner of a project leased to a tax-exempt entity. Rooftop solar compa-nies will be able to lease rooftop systems to public schools and government agencies without losing the cash grant.

Attorney Advertising. Prior results do not guarantee a similar outcome.

But, there will be loss in tax depreciation benefi ts because all assets leased to tax-exempt entities are subject to a slower tax depreciation allowance. A solar project leased to a tax-exempt is depreciated over 12 years (or 125% of the lease term if longer) on a straight-line basis rather than over fi ve years on an accelerated basis. Other tax constraints on tax-exempt entity leasing may have to be satisfi ed to avoid further reductions in depreciation deductions. From a tax standpoint, to avoid a loss in the depreciation benefi ts it is still preferable to enter into PPAs with tax-exempt entities, rather than leases. Such transactions must be structured carefully to ensure that for tax purposes the lease qualifi es as a “true lease,” and the PPA is classifi ed as a service contract and not a lease. However, the parties may wish to do a direct lease for non-tax reasons.

The relaxation of the ban on cash grants for tax-exempt leasing may help projects designed for ownership by a partnership that includes members that are tax-exempt entities. Under current guidance, a project owned by a partner-ship does not qualify for the cash grant if any interest in the partnership—no matter how small or remote—is owned by a tax-exempt or other ineligible en-tity. Some unique types of tax-exempt entities that are experienced power play-ers, such as municipal utilities and electric cooperatives, may wish to enter into partnerships with developers under which the partnership would sell, lease back, and operate the project. The new rule will allow that project to benefi t from a full cash grant.

The FAQ, however, does not change the rule that if a partnership is the owner (rather than a lessee) no cash grant is available if there is any tax-exempt ownership interest in the partnership. Most private equity funds have at least some tax-exempt entities as investors. Market participants have been pressing Congress to eliminate this rule, or at least rewrite it so that partial ownership of a partnership by tax-exempt entities would not lead to a loss of the entire grant, but only that portion of the grant that is proportional to the tax-exempt entity’s interest in the partnership.

Passive loss rules inapplicableAnother cash grant development benefi ting partnerships and private equity funds was not addressed in the FAQs, but has been addressed by Treasury and the Department of Energy in other contexts. This relates to the so-called “pas-sive loss” rules that primarily affect individual investors. Any individual who is an investor in a renewable energy project, but is not involved in the day-to-day operations of the project will be subject to the “passive loss” limitations. These limitations require that the ITC and losses attributable to depreciation deductions be used to offset only passive income from the project or similar investments. Most projects will generate net losses in the early years and most individuals do not have other forms of passive income. As a result, most passive investors can only use the ITC and tax depreciation deductions from a par-ticular project to reduce the project’s own passive income. Excess credits and deductions are carried forward to future years until they can be fully absorbed by project income. This could take years, a delay that reduces the present value of the tax benefi ts compared to using them in the year they are fi rst generated.

Notably, the 30% cash grant in lieu of the ITC is not subject to the passive credit limitations. Therefore, an individual investor that would be required to defer and carry forward the ITC and tax losses due to the application of the passive loss rules, can still claim and receive the full 30% cash grant in lieu of the ITC immediately. (Net operating losses attributable to depreciation re-main subject to the “passive loss” limitations.) This further liberalization of the cash grant rules should be of interest to funds that are managed for wealthy individuals who would otherwise be subject to the passive loss rules. A fund composed of taxable individual investors would be able to claim a full 30% cash grant for qualifying projects.

Commencement of constructionA third issue that has arisen in the context of the grant program relates to when construction of a project is considered to have begun. Projects must be under construction by December 31st, 2010 to qualify for grants under the existing program. Under existing guidance, a developer can demonstrate that construction has commenced by showing “physical work of a signifi cant nature” has started or that the developer has “incurred” more than 5% of the total project cost. Developers of large-scale wind and solar projects have strug-gled with the defi nition.

Treasury considers each wind turbine, pad, and tower to be a separate project, each of which must commence construction by the end of 2010. If the

developer pours concrete for the fi rst of a 40-turbine wind farm, has physi-cal work of a signifi cant nature begun on all 40 projects? If a large-scale solar project involves off-site manufacture or assembly of components, how much must have occurred before physical work of a signifi cant nature is considered to have begun? Legislative updateSeveral different bills have been or are expected to be introduced in Congress to amend or extend the cash grant program and other aspects of the stimulus bills that created it. One proposal would extend the current program’s con-struction commencement deadline from 2010 to 2012, and would extend the placed in service deadline for all renewables to the end of 2016. Another bill would alter the program by treating the cash grant amount as a tax refund. The tax refund would be paid a lot later than the current cash grant—after the tax return is fi led for the year the project is completed—and the amount of the refund would be subject to offsets for other taxes owed.

investing in clean energy

At a glance, a fi eld of wind turbines or a solar panel farm may look like a simple development involving real property and clean energy equipment. On closer inspection, the variables involved in fi nancing and closing these transactions are

often multi-faceted and complex. Projects can cover many different types of land interests: private, lease-hold interests, as well as native and federal lands. Similarly, the security a lender will take to fi nance a project is not restricted to the real property. It may also extend to the moveable assets.

If you think about the assets of the wind farm, there are the fi xed assets: the land and the concrete base for the turbine; while the wind turbine itself may be a moveable asset as it can be loaded onto a fl atbed truck and moved to another location. As such, acquiring and securing interests on renewable energy developments poses a challenge for operators and lenders because of the multiple factors at play.

One growing method of dealing with these challenges is the bur-geoning use of title insurance to streamline transactions, reduce risk, and provide the lender with security for fi nancing. Separate policies are available for owners, as well as for lenders to protect their respec-tive interests in a deal. The cost of a title insurance policy is based on the value of the property transaction. It is a one-time fee with no deductible and stays with the lender or owner for as long as they main-tain an interest in the property.

“We often get calls just as a deal is about to close because an issue has arisen and the deal cannot close on time,” says John Rider, vice president of the Commercial Division at First Canadian Title, the Canadian division of First American Title Insurance Company. “We work with counsel by taking on the risk in a transaction addressing issues such as zoning compliance, easements, off-title work orders, absence of land survey—so a deal can proceed to closure.”

Renewable energy farms often cover many jurisdictions and involve a variety of owners, leasors, and lenders. Title insurance provides the policy holder with continued secured interest over the development. This “contiguity” of secured title protects the policy holder from defects, charges, liens or encumbrances on the title, the title’s unmarketability, and the lack of a right of access.

Furthermore, some title insurers may also provide coverage for collateral that is personal property. A personal property title insurance policy can be issued concurrently with a traditional title insurance policy, eliminating concerns that lenders may have as to whether any portion of the security, like a wind turbine, falls into either the legal defi nition of realty or personal property.

“More and more companies and their legal counsel are turning to title insurance to structure their renewable energy devel-opments. Increasingly, we have become involved in the early stages of a deal on solar and wind farms, pipe and transmission lines from the get-go, because of the risk transfer we provide to parties.” advises John Rider. “One of the most attractive fea-tures of our policy is the ‘Duty to Defend.’ With so many interests involved in a complex renewable energy project, knowing that an experienced insurer will defend your interests reduces the risk for fi nancers and owners.”

“Duty to Defend” is an insurance term whereby the insurer must defend the insured’s interest if they are legally challenged. As such, a policy holder can rely on their title insurance company to take on the legal costs and challenge of defending their interest in court.

For more information, legal counsel can enquire on a party’s behalf about how title insurance can mitigate the risk of a clean energy project or development.

According to their website, the US Department of En-ergy’s (DOE) Loan Guarantee Program paves the way for federal support of clean energy projects that use innovative technologies, and spurs further investment in these advanced technologies. A principal purpose of the Loan Guarantee Program is to encourage early commercial use in the United States of new or signifi -cantly improved technologies in energy projects. DOE believes that accelerated commercial use of new or

improved technologies will help to create jobs and sus-tain economic growth, yield environmental benefi ts, and produce a more stable and secure energy supply.

To date, DOE has conditionally offered or closed 12 loans or loan guarantees. According to estimates from the companies, these projects will collectively create or save about 50,000 jobs. They will also lead to the capacity to produce more than 3 GW of clean power each year and will avoid more than 30 million tons of

CO2 per year. Vehicle projects (under the Advanced Technology Vehicles Manufacturing Loan Program) will also save—up to 270 million gallons of gasoline each year.

No extension for Canadian renewable power program The Canadian Wind Energy Association (CanWEA) recently expressed disappointment with the Canadian federal government’s failure to expand and extend its ecoENERGY for Renewable Power Program in the 2010 federal budget. The ecoENERGY for Renewable Power Program was created in January 2007, and has now allocated all of its funding and met its target to support the deployment of more than 4,000 MW of new renewable energy projects in Canada.

“The failure to extend and expand the ecoENERGY program will slow wind energy development and reduce our ability to compete with the United States for investment and jobs at a critical time in our economic recovery,” said CanWEA president, Robert Hornung. “While we remain committed to working with the federal government to fi nd ways to attract new investment in the world’s most rapidly growing source of electricity, we are shocked and disappointed that it has chosen not to extend a cost-effective program that facilitated record levels of investment and job creation in Canada’s wind energy sector in the midst of the recession of 2009.”

While the US federal government’s key incentive program will provide support for new wind energy projects constructed through to the end of 2012, Canada’s ecoENERGY program has now allocated all of its funding and is supporting no wind energy projects built after March 2011—almost two years before US sup-port is scheduled to end. The fact that fed-eral funds are no longer available to sup-port new wind energy projects in Canada means wind energy investors will increas-ingly shift new investments and job crea-tion out of Canada to the greater policy certainty and more attractive investment climate found in the United States.

“Federal government incentives have played a critical role in wind energy de-velopment in Canada by supporting and complementing provincial government initiatives in this area. The success of this partnership is clear—Canada’s installed wind energy capacity has increased 10-fold in six years,” said Hornung. CanWEA | http://canwea.ca

Solutions for poor performing wind generatorsEngineering personnel at Morgan AM & T studied wind turbine generators to determine how they could be improved with less maintenance, fewer failures, and overall reduced annual cost. This study created a “new design” that enabled wind farm owners to accomplish robust im-provements in the performance (up time) for the entire wind farm. The problems are a combination of the existing brush material, brush holders, and rigging, where all the current materials in use are not optimum. The Morgan Solutions are designed to eliminate costly slip ring damage, heavy carbon dusting, and rapid brush wear that create costly downtime and ineffi cient operation.

Morgan AM & T solutions use a fi nely machined (highly polished) brush rigging that reduces sidewall friction and utilizes full length radial holders for stability. These re-engineered designs directly and easily mount in place of the original holders and can be installed in two hours without any additional up-tower machining. It is the one and only tested and proven solution.Morgan AM & T | www.morganplc.com

REVOLUTIONARY TECHNOLOGY PROVEN TO: • Significantly Increase Wind Turbine Power Output • Dramatically Reduce Stress Loading on Main Bearing

www.catchthewindinc.com • [email protected]

VINDICATOR® LASER WIND SENSORTHE

MORE POWER OUTPUT • LESS STRESS • MORE PROFIT

The nacelle-mounted Vindicator® Laser Wind Sensor (LWS) generates three-dimensional wind speed and direction information by sensing the wind in the undisturbed air up to 300 meters in front of the turbine. This supplies the control system with the most accurate feed-forward wind measurements available, facilitating smarter turbine control.

Give your turbines the knowledge to consistently Catch the Wind!

PIINND EEENNNSSOORRR

A “smart” turbine sees the wind coming...

INTELLIGENT YAW CONTROL informs the control system before directional changes in the wind reach the turbine, which keeps the turbine blades facing into the wind. Improved alignment with the wind increases power output and reduces wind turbine maintenance costs and downtime by lowering off-axis stress loads that damage the blades, gearbox and other components.

PREDICTIVE PITCH CONTROL allows for smoother operation at rated power. Stress and fatigue can be reduced when blade pitch control is based on detecting wind gusts. Rated power output can be maintained even in inconsistent wind without additional stress on system components.

Imagine three blades that concurrently pitch, depending on wind speed, to regulate rotation speed. This technology allows for lower start-up speeds, higher effi ciency, and increased power output. With higher winds, other systems have a decreased power output because of over-speed protection, but the PowerMax+ 2000D and 5000D sys-tems are able to maintain peak perform-ance up to 56mph.

Wind power development locationThe business environment in Sweetwater and Nolan County has continued to prosper with a diverse eco-nomic base and a strong manufacturing sector. Nolan County is home to 1371 wind towers and over 2060+ MW of wind power development. They have started construction on both an equipment manufacturing facility for power distribution for EMA (Electro Mecanica out of Argentina), as well as a new industrial park with spaces available. They are a community that not only utilizes its natural resources, like wind, oil, gas, gypsum, and limestone, but also their transportation location—they are located on Interstate 20 near High-ways 70 & 84. Sweetwater has both the Union Pacifi c and Burlington Northern Santa Fe railroad lines run-ning through, and are fortunate to have Texas State Technical College West Texas as their training provider.

Wind blade effi ciency & production speedThe rapid expansion of the wind power generation market, fueled by both private and government initiatives, requires a similarly rapid increase in the production of wind turbine components. To main-tain or increase output effi ciency, larger blades must meet the divergent need of also being lighter in weight. Larger blades also require increased precision in the production process. To help increase accuracy, quality, and production speed, Carter Products introduced their CPS 3-D laser alignment system. With Cart-er’s new LP-HFD models, the improve-ments on this proven technology include more sophisticated projection capabilities and software. It is also available with a green laser output, which is more visible in many manufacturing environments, and is smaller and lighter than previ-ous models. For blade production, the Carter laser alignment systems provide an interface to industry standard CAD design software. Layout and production information is extracted from the CAD program and projected to the work area. Carter Products Company, Inc.www.carterproducts.com/windpower

Laser wind sensorCatch the Wind’s Vindicator laser wind sensor (LWS) is a revolutionary, fi ber-optic LIDAR system—the fi rst of its kind. Mounted on the nacelle of a wind turbine, the Vindicator LWS measures three dimensional wind speed and di-rection in the undisturbed air out to 300 meters in front of the turbine blades. Advanced wind data facilitates improved yaw alignment and pitch control to signifi cantly increase power output while dramatically reducing wind tur-bine stress loading. Recent trials have shown power output increases of over 12% when using feed-forward wind data from Vindicator LWS to make smarter control decisions. In addition to intelligent turbine control, this LIDAR technology is easily deployed for both terrestrial and offshore wind resource assessment and site prospecting.

With a crawler chassis only 5.8m wide, the LR 1600/2-W can move, fully equipped, along the narrow tracks on wind farms from one installation to the next. The crane is supported for hoisting work. For optimum movement, the new nar-row track version of the 600-tonner from Liebherr comes as standard with a four-fold crawler drive. Likewise stand-ard are the two-metre-wide track pads on the crawler carrier, which enable the ground pressure to be reduced. Liebherr-Werk Ehingen GmbHwww.liebherr.com

No longer is the power generation industry dependent upon the utilization of food crops to supply suffi cient

biomass for a power station. Bianchi Energy Solutions LLC, through its subsidiary White Technology, LLC, has conducted research to fi nd plant species that address the needs of the power industry, but do not divert food-based crops. Efforts have been focused around perennial rhizomatic grasses.

“Perennial rhizomatic grasses are a classifi cation of energy crops that are noted around the world for their potential as excellent biomass sources,” according to Kenn Davis, president of White Technology. “Through our extensive research into bio-energy crops, we have identifi ed two species that make terrifi c sources of biomass: Miscanthus giganteus and Giant Reed (Arundo donax). These energy crops have the ability to produce strong yields, with test plots indicating that annual yields can exceed 20 dry tons of biomass per acre within an 18-month period from the initial planting, with yields in warmer climates of the United States exceeding 25 dry tons per acre.”

Miscanthus giganteus is a genus of “woody” rhizomatous peren-nial grasses, growing nine to 12 feet in height. The plant grows new shoots annually that produce erect, robust stems and appear similar to bamboo canes, having a diameter of approximately two centimeters. As a biomass crop for the US, yields of 15 to 25 dry tons per acre make this plant a very attractive choice for feed-stock. Studies have shown Miscanthus giganteus to grow and pro-duce high or reasonable yields on a wide variety of soils, ranging from sands to high organic matter soils. Studies also have shown that Miscanthus giganteus tolerates a wide range of pH values.

Giant Reed is a giant perennial grass. Studies have shown that it produces more biomass per acre than any other non-food bio-mass plant. Giant Reed is recognized as an important non-wood industrial biomass-producing plant that can be grown on a wide variety of soil types and under a wide range of climatic condi-tions. The plant reaches a height of 15 to 25 feet in approxi-mately 18 months after initial planting. Annually, Giant Reed can produce 20 to 25 dry tons of high-quality biomass per acre.

One of the most signifi cant uses of Giant Reed will be to pro-duce chipped fuel feedstock for biomass power production. Also, the plant can be used to supply coal power stations with a stable co-fi ring material reducing CO2 emissions by up to 50%. Giant Reed is distinctive in that it has a lifespan of up to 25 years with-out the need for annual tillage. Testing indicates there is little or no need for additional fertilizer after the fi rst two years, and its probable growth is among the highest on the planet.

Another benefi t of both Miscanthus giganteus and Giant Reed is the ability to use these plants for remediation purposes. Stud-ies have shown that these grasses can remove most toxins from the soil, especially organohalogens. Because of their C3/C4 photosynthetic processes, these plants retain the extracted toxins

in their roots, eliminating any potential contamination from the use of the plants’ stalks or leaves.

Although Miscanthus giganteus and Giant Reed have tremendous potential as an energy crop, as well as for phyto-remediation, the ability to grow these plants on a large scale has, to date, been diffi cult. Both are sterile grasses due to the polyploidy of the plants. The traditional method to grow these grasses has been through rhizomatic propagation, which uses root systems to produce new plants. The arduous nature of this process limits the ability to produce these plants on a large scale.

To solve the production issue, an exclusive license from the University of South Carolina has been obtained related to a micro-propagation process that is well suited for large-scale production of Miscanthus giganteus, Arundo donax, and other po-tential energy crops. The micro-propagation process, developed by Drs. Laszlo Marton and Mihaly Czako, will allow White Technology to effi ciently and effectively produce millions of plants on an annual basis for use in agricultural operations and for phyto-remediation purposes.

To augment these efforts, Bianchi Energy Solutions has researched farming techniques for these grasses. This research indicates that some traditional farming techniques can be used for the planting, monitoring, and harvesting of these perennial grasses. However, it has been determined that certain crop-specifi c techniques are required to ensure productive biomass yields and, as a result, a turnkey energy crop offering for parties interested in using these plants for energy crops or phyto-remediation has been developed. This offering includes procuring plants, crop planting, crop monitoring, and harvesting guidance and also includes access to proprietary planting and harvesting equipment.

With regard to crop monitoring offering, Bianchi Energy Solutions not only monitors the crops to improve biomass yields but also works with farming operations to minimize the poten-tial encroachment of the crops into surrounding areas.

“While the sterile seed of these grasses greatly reduces any invasive attributes of the plants, we still recommend that proce-dures be put in place at the farming operation to limit any en-croachment,” said Davis. Strategies have been generated to limit such encroachment.

David Allen is the director of sales and marketing at White Technology.

Case Study: Advancements in Energy Crop ProductionBy David Allen



Volatile gasoline prices, concerns over global climate change, fossil fuel de-pendence, and the desire to expand domestic agricultural economies have led

to increased interest in biofuels as an alternative to petroleum in the US transporta-tion sector. Ethanol is blended into nearly half of all US gasoline. Today, most of the ethanol in the US is produced from starch contained in corn.

The cellulosic ethanol industry involves turning renewable biomass, such as crop residues and bionenergy crops, into fuel-grade ethanol. This year, the industry has reached an important point in its evolution. The science is ready, the federal government has re-affi rmed advanced biofuels mandates, and projects to scale-up production are underway. Within the next few years, the industry aims to deliver cellulosic ethanol that is competitive with gasoline.

Producing cellulosic ethanol involves converting lignocellulosic feedstocks, such as crop residues like corncobs and energy crops like switchgrass, into liquid fuel. Due to strong biofuels research over the past decade, conversion technology is already highly advanced. The technology continues to improve, but the main chal-lenges to scale-up and deployment are optimizing engineering and establishing a reliable, cost-effective biomass supply chain. Of the many cellulosic ethanol projects

under development and construction around the US, most are still in lab or pilot phase. However, a few leading players are poised to deliver commercial production within the next three to four years.

In January of this year, DuPont Danisco Cellulosic Ethanol (DDCE) cut the rib-bon on a demonstration-scale facility in Vonore, Tennessee, which marked a mile-stone for the advanced biofuels sector. The cellulosic ethanol industry is under a federal mandate to deliver 36 billion gallons of renewable fuel by 2022, of which 16 billion gallons must come from cellulosic sources. The DDCE project is one of the fi rst demonstration-scale facilities for cellulosic ethanol, and is unique in its focus on converting both crop residues and energy crops, which means it plays an impor-tant role in advancing the industry toward commercial-scale production.

The Vonore facility is a collaboration between DDCE, the state of Tennessee, and Genera Energy. The plant has the capacity to produce 250,000 gallons of cel-lulosic ethanol annually, but its main purpose is to test and validate processes for large-scale production. The fi rst commercial plants will produce between 25 and 50 million gallons of ethanol per year.

Production processEthanol from lignocellulosic sources is often referred to as 2nd generation ethanol. It differs from 1st generation ethanol made from starchy materials because break-ing down lignocellulosic plant materials is a fairly complex process. DuPont and Danisco took on this challenge by forming the DDCE joint venture to integrate the companies’ proprietary technologies into a complete production solution, es-sentially bringing together a long history of R&D work in biofuels.

The basic steps in cellulosic ethanol production are pre-treatment, saccharifi ca-tion (hydrolysis), microbial fermentation, and distillation and dehydration...• Pre-treatment. Lignocellulose has a very rigid structure that must be broken

down to make the sugars—hemicellulose and cellulose—accessible. There are several methods for pre-treating biomass that run the gamut from acid hydroly-sis to steam explosion. The DDCE pre-treatment process applies a proprietary mild alkaline technology. The method, which uses steam and ammonia to break down the plant material, is not as harsh as some others and minimizes degrada-tion products that can inhibit the subsequent production steps.

• Saccharification (also called hydrolysis). The pre-treated biomass is trans-ferred into the saccharifi cation equipment to break down the biomass into its component sugars. Saccharifi cation technologies usually involve acid or en-zymes. DDCE has been able to improve production economics signifi cantly through its enzyme technology. The enzymes work in relatively mild tem-perature and pH conditions, diminishing formation of byproducts that inhibit enzyme activity. Onsite enzyme production also provides performance and cost advantages.

• Fermentation. The “hydrolysate” that leaves the saccharifi er is full of 6-carbon (hexoses) and 5-cabon sugars (xylose and arabinose). The hydrolysate heads to the fermenters where microbes convert the sugars to ethanol and byproducts.

• Distillation/dehydration. Finally, the fermented ethanol enters the distillation and dehydration processes where it is brought to fuel-grade ethanol.

Commercial Production of Cellulosic Ethanol

Cellulosic ethanol as a sustainable fuelEnvironmental sustainability is integral to commercial success for cellulosic etha-nol. To meet, and exceed federal emis-sions thresholds, rigorous lifecycle analy-ses examine total environmental impacts of cellulosic ethanol. Depending on the feedstock used, cellulosic ethanol can reduce transportation greenhouse gas emissions from 85% to 130% over its li-fecycle compared to gasoline. The emis-sions advantages are achieved because the biomass recaptures carbon when it undergoes photosynthesis. Cellulosic ethanol biorefi neries further reduce en-vironmental impacts through features such as water recycling and by-product capture. Prior to distillation, energy by-products are captured to sell or provide energy for the cellulosic ethanol facility.

The cellulosic ethanol industry is prepared for a busy and exciting decade during which it will meet those mandates and play a key role in building the clean energy economy.

Biofuel manufacturing process: Preventing fi res & dust explosion Bioenergy and biofuel manufacturing has become one of the fastest growing industries for spark detection systems. This is due to the aggressive nature of shredding, granulating, and pelletizing processes and the high risk of generating ignition sources, which are quickly conveyed along the production line. Sparks are commonly generated by the process of pellet, disk, and briquettes production. These sparks can ignite product and waste dust causing fi res and dust explosions within fi lters or along conveying systems. The GreCon system is a preventative system, which detects initial sparks or glowing embers and extinguishes them before they cause a fi re or an explosion.

The main areas where a spark detection system is used are: rotary dryer; hammer mill; pellet press; pellet cooler; silos; conveyors; and, extraction ductwork to protect fi lter units. Sparks, glowing embers, hot particles, and burning material are all extinguished without shutting down the conveying systems, damaging fi lter bags, or interrupting production. Improvements in plant safety and insurance risk are important benefi ts, but the primary reasons for installing a GreCon spark detection system is to reduce the risk of personnel injury, plant downtime, and to protect production volumes and market share.

Solving the cold soak dilemma in biodieselSchroeder Biofuels has announced the release of two new product sizes for ColdClear, the fi rst multi-stage treatment system for solving the cold soak dilemma in biodiesel and biodiesel blends. After some great success with the 5, 15, and 45 gpm ColdClear units, Schroeder recognized the need for a 60 gpm unit, BCC1200, and a 75 gpm unit, BCC1500. Both of the new sizes are built on the same foundation of the original ColdClear unit. With the introduction of these new sizes, ColdClear can now be implement-ed in larger plants and diesel fuel distribution centers.

ColdClear is a proprietary, multi-stage separation technology designed specifi cally to ensure that biodiesel products conform to the new ASTM D6751 Standard for cold fl ow properties.

Waste energy generatorCyclone Power Technologies Inc., and its licensee Phoenix Power Group LLC (PPG), announced that Clean Burn Inc. has joined the team to help develop and market the fi rst commercial electric generator system running on waste oil. The Phoenix waste energy recovery system will be powered by Cyclone’s heat-regenerative, external combustion engine. An initial system based on the Cyclone Mark V engine is expected to produce approximately 30kW to 55kW of grid-tied electricity from the clean combustion of used oil, a renewable fuel source. The team anticipates bringing beta versions of these environmentally benefi cial products to businesses like oil change shops, transport fl eet operators, airports, and railroad yards later this year. Clean Burn will be providing engineering expertise to the project in the areas of waste oil delivery and fi ltration, combustion systems, UL testing, and emissions standards.

Waste motor oil is a major source of contamination of waterways and can result in the toxic pollution of drinking water sources. According to the US Environmental Protection Agency, waste oil from one oil change can contaminate one million gallons of fresh water, equivalent to a year’s supply for 50 people. Ad-ditionally, the US Department of Energy has estimated that the effi cient recycling of wasted energy such as used oil over the next 20 years can help reduce the national dependence on petroleum imports, spark billions of dollars in private investments, and create up to one million jobs in the US.Cyclone Power Technologies, Inc. | www.cyclonepower.com

RFS2 readyRenewable Energy Group (REG) offi cials welcome the Environmental Protection Agency’s (EPA) is-suance of the fi nal rule to implement the expanded Renewable Fuels Standard (RFS2), which includes a national volume requirement for biodiesel.

“The implementation of fi nal RFS2 rules is a long-awaited victory for our clean biodiesel energy in-dustry and our nation’s energy independence,” said Renewable Energy Group’s chief executive offi cer, Jeff Stroburg. “In addition, we urge our leaders to extend the biodiesel blenders tax credit to ensure short-term success of this clean energy industry and help keep our clean energy workers, working.”

Under the RFS2 fi nal rule recently released, biodiesel’s greenhouse gas emission improvement threshold makes the fuel eligible in two categories: biomass-based diesel and advanced biofuels. The rule calls for combined 2009 and 2010 volume requirements of 1.15 billion gallons of biodiesel to be utilized by the end of compliance year 2010. As anticipated, biomass-based diesel will earn 1.5 RINS.

As a multiple feedstock biodiesel producer, REG applauds EPA’s re-consideration and utilization of updated science-based models for crop yields and indirect land use calculations, as well as values for co-products like glycerin.

“REG markets both glycerin and fatty acid as co-products of biodiesel production,” said REG VP, supply chain, Dave Elsenbast. “We are proud to have worked in close coordination with industry part-ners to supply accurate production and value data for comments to the EPA, which led to an updated greenhouse gas emission reduction number qualifying all biodiesel feedstock as eligible under the RFS2,“ Elsenbast added.

hydro and marine energy

While solar and wind remain at the forefront of most renewable energy dis-cussions, another form of power generation is emerging that has the poten-

tial to be a signifi cant source of energy: osmotic power. Osmotic power is created through the natural phenomenon of osmosis. When

two fl uid streams of varying salt content—such as low-salinity river water and high-salinity ocean water—meet on either side of a membrane, osmosis causes the less salty water to be drawn toward the seawater side. The membrane blocks the salt, allowing only fresh water to fl ow through. This creates a pressure on the seawater side that can be used to drive a turbine to generate electricity.

In November 2009, Norwegian energy company Statkraft opened the world’s fi rst pilot osmotic power plant in Tofte, Norway to demonstrate the viability of this emerging alternative energy source. According to Statkraft’s research, osmotic power has a global potential of 1,600 to 1,700 terawatt hours (TWh) annually. To harness this energy production potential, it is essential to understand precisely how the process works, the challenges of the technology, and the critical elements neces-sary to overcome these hurdles ensure the net-positive production of energy.

How osmotic power worksIn the natural world, osmosis requires three components: a low-salinity water sup-ply, a high-salinity water supply, and a membrane that blocks the salt while allowing fresh water to fl ow through it. To sustain osmosis in a man-made process and create osmotic power, the same three elements are required. For example, river water can serve as the low-salinity water supply, the ocean can supply the high-salinity water, and membranes capable of separating salt from water, which have been developed for modern desalination applications, can be adapted for osmotic power.

When the river water and seawater merge, osmosis causes water to fl ow through the membrane from low salinity to high salinity. The membrane selectively blocks and fi lters out salt, only allowing fresh water to pass through. The force exerted by the water—called osmotic pressure—is highest when the salinity difference across the membrane is the greatest. Therefore, wherever a river fl ows into the ocean, os-motic energy is potentially available if an effi cient osmotic power process is used.

The osmotic power process is illus-trated in Figure 1. Low-salinity water and high-salinity water are supplied to the opposite sides of a membrane. Fresh water is drawn across the mem-brane by the seawater, building pres-sure on the seawater side and diluting it. The pressure of the diluted seawater is released through a turbine, which turns a generator to make electricity. The diluted water fl ows to the sea just as it would have without the process. The result is a clean, continuous source of renewable energy.

Overcoming challenges of the osmotic power process Maximizing energy output through the osmotic power process is not as simple as mixing river water and seawater. To understand the challenges that must be over-come, consider the diagram of a basic osmotic power process shown in Figure 2.

Seawater is supplied to the membranes with a high-pressure pump. River water is supplied to the membranes at low pressure. Osmosis “pumps” the river water across the membrane where it merges with the seawater, increasing its fl ow rate. This dilute water is released through a turbine

that drives a generator. In this design, the high-pressure pump consumes electric-ity and the turbine produces electricity. Because the fl ow rate through the turbine is greater than the fl ow rate through the high-pressure pump, the process has the potential to produce more energy than it consumes.

However, one of the challenges is the dilution of the seawater. As the river wa-ter mixes with the saltier ocean water, the osmotic pressure reduces. With a lower osmotic pressure, the driving force that moves the water across the membranes is reduced. Therefore, more seawater must be supplied at high pressure to keep the permeate fl owing and maintain high pressure in the dilute water stream—a process that consumes more energy and reduces the net power output.

A second challenge is mechanical losses in the pump, turbine, and generator. Even large, effi cient modern devices experience some losses when they convert electrical energy to hydraulic energy or vice versa. A more viable design would eliminate the high-pressure pump so that more of the electricity generated by the turbine could be sent to the electric grid.

The high-effi ciency osmotic power processTo overcome the challenges associated with the basic osmotic power process, en-ergy recovery devices can be inserted into the process. As outlined in Figure 3, an energy recovery device eliminates the high-pressure pump and only a portion of the dilute water from the membranes passes through the turbine.

The rest of the high-pressure dilute water fl ows to the en-ergy recovery device where it is replaced with salt water. This exchange occurs at extremely high ef-fi ciency, with no en-ergy consumption and without signifi cant reduction of the pres-sure of the stream. A

circulation pump (which consumes very little energy because it does not pressurize the stream) moves the now pressurized salt water through the membranes to be diluted again in a continuous process. As a result, nearly all of the water that enters the high-pressure loop through the membranes leaves through the turbine.

Incorporation of energy recovery devices solves both the problems identifi ed in Figure 2. Specifi cally, this technology allows for the replacement of the high-pres-sure pump with a low-energy circulation pump and limits the fl ow through the tur-bine to just that necessary to produce net power, making the process more effi cient. Energy recovery devices also effectively keep the salinity in the high-pressure loop high, increasing the driving force for osmotic power production.

Potential powerOsmotic power has tremendous potential as a global source of renewable energy and Statkraft is already demonstrating the net-positive production of power at its pilot facility in Norway. The plant is designed with a capacity of 10 kW and by 2015, Statkraft plans to build a full-scale osmotic power plant with a capacity of 25 MW, which could produce more than 166 gigawatt hours (GWh) of electricity per year—enough to power 30,000 homes in Europe.

The potential for osmotic power is undoubtedly signifi cant, but requires precise engineering and a design that properly addresses the challenges associated with the basic osmotic power production process. Eliminating the high-pressure pump by implementing highly effi cient energy recovery devices into the process helps en-sure net-positive production of electricity. Signifi cant refi nement of the membrane technology is required before this process becomes commercially viable. However, the incorporation of energy recovery devices will help the world to realize the enor-mous potential of osmotic power as an emerging source of renewable energy.
