Developing Nevadas Clean Energy Resources
October 2010
1. Executive summary
Nevada currently imports nearly all of its fuel for energy, whether in the form ofnatural gas, coal, petroleum or electricity. However, the state has vast domestic energyresources in the form of renewables and energy efficiency. Nevada has an opportunity
to save over $300 million dollars per year by 2025 due to decreased energy importsand increased electricity exports if the state aggressively pursues the development ofits clean energy resources. In this scenario of clean energy export plan, Nevada couldincrease its GDP by $540 million and create over 9,000 clean energy jobs directlysupporting the new clean energy infrastructure by 20251.This report explores the path we are currently on for clean energy development inNevada and the opportunity in Nevada to build a stronger clean energy economy inmore detail. It presents plausible pathways to capturing the value at stake, quantifiesthe impact of these pathways on Nevada ratepayers, jobs, and GDP, describes likelybarriers to achieving the opportunity, and discusses potential policy and other measuresthat could help overcome these barriers.
2. The opportunity for developing clean energy in Nevada
Nevada imports nearly all of the fuel required to generate electricity for the statesconsumers and businesses. In 2008, almost 90% of the electricity generated in Nevadawas from out-of-state fuel sources (Figure 1). This power was produced using $1.7billion of imported fossil fuel: $1.3 billion of natural gas and $400 million of coal. Inaddition, Nevada imported 1.2 million MWh of electricity (3.4% of its electricity,worth approximately $60 million) from out-of-state generators.
1 This accounts for green jobs associated with building and operating renewable energy facilities and transmission lines, and retrofitting buildings. Does not account for job losses in other industries

However, Nevada has large and high-quality renewable energy resources and significant energy efficiency potential. The combination ofenergy efficiency and renewable power could reduce Nevadas energy imports, increase its exports of electrical power and stimulate alocal clean energy industry.
Renewables
Nevada has among the best geothermal resources in the country. Geothermal energy could theoretically supply between 1,500 and 3,000MW of baseload generation capacity (10 20 million MWh of energy per year, or 30-60% of Nevadas total demand), a potential secondonly to California. Much of the state, particularly the north, contains known or potential geothermal resources (Figure 2). In addition,geothermal power generation has an established track record and a potential that will continue to grow as exploration technologies arerefined and costs drop.
In 2008 almost 90% of theelectricity generated in Nevada
was from out-of-state fuel sources(Figure 1). This power was
produced using $1.7 billion ofimported fossil fuel: $1.3 billion of
natural gas and $400 million ofcoal. In addition, Nevada
imported 1.2 million MWh ofelectricity (3.4% of its electricity,worth approximately $60 million)
from out-of-state generators.

Nevada also contains world-class solar resources (Figures 3 and 4). Solar energy, including both solar thermal and utility-scalephotovoltaic generating plants, could theoretically provide orders-of-magnitude more electricity than needed to meet Nevadas peakdemand. The limiting factors for solar generation are therefore not the size of the renewable resource, but siting, transmission andeconomic constraints.

Other renewable resources in Nevada include wind, distributed generation (mostly solar photovoltaic) and solar hot water heaters. Nevadahas between 15,000 and 20,000 MW of wind energy potential. There is several hundred MW of distributed solar PV potential on homesand commercial buildings, which could provide hundreds of thousands of MWh of energy per year (a few percent of total demand).Finally, solar hot water heaters could reduce electricity demand by displacing electric water heaters, potentially saving 1.2 1.5 millionMWh (3-4% of total demand) per year (and removing the need for ~350 MW of generating capacity).2
Energy efficiency
A report published in 2009 by McKinsey & Company examined in detail the potential for greater efficiency in non-transportation uses ofenergy, including the effect of measures such as retrofitting homes, installing more efficient appliances and lighting and constructingmore energy-efficient new buildings.3 It found that the U.S. could save up to 23 percent of projected energy demand in the residential,commercial and industrial sectors. These measures, if put in place, would cost $520 million but save a total of $1.2 trillion in energy costs.

This large net savings could be obtainedbecause the cost of energy efficiencymeasures is usually significantly lowerthan the cost of energy. For example, gas
generation costs 5-7 cents/KWh, whereassaving a KWh of energy through efficiencycosts on average about 3 cents/KWh.4
In Nevada, the total economic (NPV-positive) energy efficiency potential inbuildings and industry using knowntechnologies is 153 trillion BTUs in 2025,
or 26% of Nevadas estimated energyusage in those sectors (Figure 5). Althoughthis potential savings opportunity is large,capturing it in practice could be verydifficult, given multiple barriers thatimpede the deployment of energyefficiency measures. Most energy efficiency programs are expected to capture less
than a third of the total economic potential. The barriers to capturing energyefficiency, and ways to overcome them, will be discussed in Section 5.
The largest energy efficiency opportunity is in residential and commercial buildings,where measures such as retrofitting homes (improving insulation, sealing ducts,replacing windows, etc.), using more efficient appliances and lights and adhering tostrict building codes could save about 30% of energy use in these sectors.
Electricity savings specifically are of interest for this report. Energy efficiencymeasures could save up to 13 million MWh of electricity (33% of total electricity
demand in 2025), removing the need for about 3,000 MW of generating capacity, or 30% of todays capacity.

Typically, energy efficiency refers to demand-side savings, but there may also be a significant opportunity on the supply side. Variousestimates suggest 2% to 6% savings from such measures as transmission loss reduction and voltage variation reduction,5 resulting in 0.88-2.4 million MWh of energy savings.

3. The economics of renewables and efficiency
Renewables.
There are multiple economic impacts from building renewable generation. Primary effects include the following.

Figure 6 shows job creation numbers for typical projects in a two year time period: a 100 MW solar PV installation, a 100 MWgeothermal plant, a 100 MW wind farm, and a 200-mile long 500 kV transmission project. The total job impact is due to directconstruction, engineering, and other project jobs; indirect jobs from demand along the renewables supply chain; and induced jobs createdas the income earned in direct and indirect sectors is spent on additional products and services (e.g., restaurant meals purchased byrenewables construction workers). These job gains will be accompanied by a small number of job loss in sectors where demand isreduced (e.g., coal and gas generation). However, because Nevada has no significant coal mining or natural gas production, these losses
are found primarily in other states.

Energy efficiency
The economic impacts of energy efficiency are broadly similar to those of renewables, in that that both types of measures require upfrontcapital expenditures and result in reductions in fossil fuel expenditures. In addition to the above benefits, cost effective energy efficiencyprograms will: (1) significantly reduce electricity bills, stimulating the local economy and making business more competitive, and (2)
have a positive impact on jobs, as they tend to shift spending away from capital intensive energy industries and toward labor intensiveservice industries (e.g., duct sealing, home retrofitting, etc).
Figure 7 illustrates the level of short-term job creation expected from a 1-year home retrofit program with $60 million in subsidies, whichcould potentially enable 5% of Nevadas homes to have energy efficiency retrofits, could create 1,680 jobs of various types during theprogram. Longer term effects not captured in this figure include the impact of accompanying tax increases and energy bill reductions.

Savings from energy efficiency measures can be large. For example, a 10% reduction8 in energy use in residential and commercialbuildings in Nevada due to energy efficiency would save $350 million per year in energy costs (electricity, gas and other fuels). Anoptimized energy efficiency program could obtain this level of savings for $1.6 billion in upfront investment, paying for itself in less than5 years.
8 This level of reduction would be equivalent to 27% capture of the economic potential identified in the 2009 McKinsey report Unlocking Energy Efficiency in the U.S. Economy, which is towardthe top end of the range (10-30%) of EE program historical performance and of expert estimates

To understand the overall economic implications for Nevada, we modeled two clean energy and EE development scenarios (Figure 8). Inthe first scenario (BAU), Nevada develops renewable resources and achieves energy efficiency sufficient to meet its RPS target. In the
second scenario (Export), Nevada achieves additional demand reduction through energy efficiency, develops slightly more renewableenergy for domestic consumption, and develops a significant amount of renewable resources for export. Figure 9 shows the electricalenergy produced from various sources in Nevada with the corresponding generation capacities installed, and Figure 10 breaks down thesame information for renewable energy.9 Energy efficiency measures could significantly reduce electricity consumption, with savingscoming from residential and commercial buildings and industry (Figure 11).

In order to deploy the renewable resources for each of the scenarios, additional transmission lines and upgrades to existing lines will haveto be completed. In addition to the assumed completion of the initial portion of the ONLine transmission project (A 600 MW, 500 kV lineconnecting the northern and southern transmission grids for the first time), we modeled a deployment of 750 miles of average 500 MW
capacity, at a cost of $1.3 billion (for BAU) and an additional 400 miles of average 350 MW capacity, at an additional cost of $0.7 billion(for the export scenario). The transmission construction requirements were based on a recent study examining potential renewableresource zones and transmission requirements throughout Nevada (Figure 12).10 The bulk of the new transmission would be along thewestern border, connecting solar (in the south) and geothermal resources both to Nevadas grid and to California, and in the east centralportion of the state, connecting geothermal and wind resources to the Nevada grid.

Implementing these scenarios would have the following impacts:
Electricity bills
Including the cost of investment in infrastructure for a robust cleanenergy economy, Nevada household electricity bills would decrease
because of the reduction in energy use due to energy efficiency(Figure 13). Bills could be kept even lower if Nevada focused moreon energy efficiency and less on renewables in the early years. Forexample, by loosening the intermediate RPS target (from 20% to15% by 2015) but also imposing an intermediate EERS target (5%by 2015), the electricity bill savings would roughly double, from$1.50 per month per household to $3.00 per month per household.

Jobs and GDP
The total impact on Nevadas economy in terms of jobs and GDP is positive in both scenarios in most years (Figure 14). This is becausethe negative impact of higher prices is more than offset by the positive impact of clean energy investment and the savings due to energyefficiency, including increased electricity exports and reduced natural gas imports (Figure 15). The export scenario has significantly better
outcomes than BAU, especially in 2025 when there is more clean technology investment and exported power.

Additional effects
Manufacturing (only from the export scenario)
If half of the energy exported in the export scenario in 2025 were produced from solar PV, and Nevada were to establish the localmanufacturing capacity to supply those PV installations, an additional 1,200 to 1,300 jobs could be created.
Local taxes
Renewable installations contribute significant taxes and other revenue (e.g., land leases) to local communities. Since most renewable
power plants would be located in rural areas, these taxes could have a significant positive impact on rural communities. In the export

scenario, roughly $25 million in local taxes and assessments would be collected from renewable power installations. This would enhancethe services provided by local governments and create 300-400 rural jobs. Taxes on transmission lines would be significant too.

6. What will it take to capture the opportunity?
In order to capture the clean energy opportunity in Nevada, three critical issues must be addressed. First, there must be a significant andsustained investment in transmission both new lines, and upgrades to existing lines. Second, several key barriers to renewable energy
development must be addressed and removed or reduced. Finally, multiple and persistent barriers to capturing the energy efficiencyopportunity must be addressed.
Transmission
The key challenge in developing renewable resources is transmission. Many resources are located far from load centers, and developing arenewable industry for export will require additional long-distance transmission capacity and upgrades of existing transmission lines. Theplanned 600 MW ONLine project connecting the northern and southern grids will help to deliver geothermal resources from Northern
Nevada to Southern Nevada, but additional high-capacity lines will be needed to connect individual installations to the grid and to exportrenewable energy to California.
In the export scenario,roughly $25 million in
local taxes andassessments would be
collected from renewable
power installations.

Despite the difficulty in capturing the full potential, many policy, market and other mechanisms exist and can be deployed to address thebarriers (Figures 16 and 17) and capture part of the potential. Effective measures include an overall energy efficiency target coupled withremoving disincentives (rate decoupling) or adding incentives (rate of return on EE investment, sharing benefit of EE with customers) forthe utility, information and education, incentives and financing, codes and standards and third-party involvement (in which a third party,
