Look behind the scenes of Smart Grid deployments and
technologies and youll discover a common challenge andopportunity to them. Theres new data, and lots of it.
From real-time, granular weather analysis and forecasting
for wind and solar power generation models to individual
home energy consumption tracking, massive new volumes
of data are being created. Indeed, a new industry term,
hanalytics has been coined to describe the analysis of
residential home energy patterns to optimize use and reduce
energy costs. The challenge and opportunity for utilities,
service providers, and consumers is to intelligently manage
this data and make sense of it.
Consider these Smart Grid scenarios that can occur in the
not too distant future:
A company that provides demand response (DR)
management services uses meter and home area network
(HAN) data aggregated from customers in neighborhoods,
microgrids, or business campuses to shed loads (reduce
electricity use) at specic times of day. Participating
customers benet by shedding load and from either
lower electricity rates or payments rewarding theirenergy-reductive behaviors.
An energy storage farm manages megawatts of stored
energy derived from variable energy sources such as
wind or solar, and applies complex analytics to detailed
weather models to predict how much energy they can
safely bid and discharge daily into a regional power
market while maintaining energy reserves to conform
with market requirements.
The eet manager of a municipalitys electric vehicles
(EVs) uses historical data along with predictive softwareto conduct carbitrage and create detailed charge and
discharge schedules for the eet to sell back electricity
to the grid and create a new source of revenues for its
constituents.
Current Smart Grid projects include utility initiatives that
are focused on upgrading the existing transmission and
distribution networks with intelligent electronic devices
or IEDs and smart meters to deliver remote monitoring
and management capabilities. The volumes of data thatIEDs accumulate will challenge human capacities to
assess and respond, so operations centers for utilities,
transmission companies, and power generators must rely
on computing power to assist in intelligent management of
the giga, tera, and petabytes of data routinely collected.
Analysis of this data can be used to develop predictive
maintenance schedules for transmission and distribution
assets and insights into grid stability. Real-time analytics
will automatically trigger reactions in response to critical
conditions that threaten the reliability or safety of the gridand avoid brownouts and blackouts.
The growing number of distributed generation and microgrid
facilities also presents challenges and opportunities in
data management for power markets and utilities. For over
a century, business models and operations have been based
on centralized power generation with extensive investments

in transmission assets to bring electricity to commercial,
industrial, institutional, and residential consumers.Integration of localized renewables and distributed energy
storage assets into the grid, co-located with consumers,
creates new business needs for software and reliable
communications networks to transmit data about asset
status and respond to requests to add power to the grid
or to island (disconnect) microgrids from the larger grid
to reduce electricity demand at critical times. Since
electricity moves at the speed of light, these transactions
must also occur with little or no human intervention,
relying on automated business intelligence solutions tomaintain grid stability.
All of these examples illustrate that the Smart Grid needs
intelligent data storage and applied business intelligence
to manage new volumes of data that exceed existing
utility and grid infrastructures and operations. The data
management challenges are signicant, but the benets
to utilities, consumers, and our global environment gained
from computer-aided analytics and decisions make the
efforts worthwhile.

In recent years, the vision for a smarter electricity grid has
been painted vividly by a broad spectrum of academics,entrepreneurs and utility company executives. By now,
the storys familiar: Improving the grid with intelligent
infrastructurein turbines, transmission lines, toasters
and everything in betweenpromises to greatly reduce the
nations energy consumption and carbon emissions, spur
the growth of renewables, enable the broad use of electric
cars, and save Americans billions.
The vision is compelling but the job of making it real
is enormous.
The grid is an immensely complex (if still technologically
primitive) ecosystem populated and shaped by hundreds
of utilities and regulatory agencies with widely varying
priorities, thousands of suppliers offering non-standard
approaches, and millions of customers with vastly different
needs. Can we evolve the current power infrastructure into
a far more advanced state? Is it mostly still hype, or is
there evidence that the smart grid has already been born?
This was the topic of a panel I moderated earlier this at
Fortunes Brainstorm Green conference about business and
the environment. With representatives from GE, Cisco,
Google, and a leading cleantech venture rm on the
panel and executives from major utilities, automakers, IT
companies, smart grid start-ups, and other players around
the table, I wanted to tease out whats happening now, not
more talk about tomorrow.
What did we learn? The full realization of the smart grid
from turbines to toasters, as GEs Kate Brass saidremainsdecades away. But progress has been encouraging in the
last year. The federal government has allocated over $4
billion of stimulus funds to smart grid projects. This is
expected to lead to the deployment of an additional 18
million smart metersdigitized metering devices that
are one of the core building blocks of the smart gridon
top of the 10 million already in place. Likewise, there are
now over 40 gigawatts of power use that can be turned
down remotely when demand peaks, helping to reduce the
need for costly (and still largely dirty) new power plantsnationally.
But the best examples of the smart grid in action were at a
smaller, more human scale, highlighting that when tackling
such a complex challenge, simplicity is key.
Michael Terrell of Google, whose web-based and smartphone-
readyPower Meter is designed to give consumers more insight
into their energy consumption, told us how he discovered,
to his surprise, that he was paying for his neighbors useof the laundry room in his apartment building. The typical
consumer, he said, has about of 500 watts of their own
hidden, always on powerfrom outdoor lights, to little-
used appliances, to poorly wired applications.
One participant objected that many smart meter consumers
have been forced to pay for the new devices, but havent

seen their bills go down yetwhich led to a small smart
grid backlash amongst utility customers in Bakerseld,California last year. Another noted that the typical energy
bill is too small and consumers too busy for most to bother
with any of the advanced analytics and power management
options that smart meters will eventually make possible.
Good points. But James Connaughton of Constellation
Energy, the former Chair of the White House Council
on Environmental Quality under Bush, had a good
answera simple orb theyve developed that you plug in
over your kitchen counter that glows red when power isexpensive and green when its cheaper. Smart, yes, but
most importantly, simple.
There were many more examples of how the rise of the
smart grid doesnt have to wait for the entire grid to
be transformed.
Tony Posawatz, whos leading the development of
the soon-to-be-released Chevy Volt (with the perfect
name) told of GMs plans to use its On-Star system tohelp manage power demand for users charging the car.
Lew Hay, the CEO of Florida Power and Light, spoke of
using real-time lightning-strike satellite data to better
predict where power outages are likely to have occurred.
And there were plenty of reminders of how far we still
have to go. As Jeff Taft, Ciscos chief architect of smartgrid solutions noted, In the past, a successful career for
a utility engineer was if they didnt break the equipment
they found when they started. Wholesale transformation is
certainly difcult in the face of that kind of culture.
Yes, the smart grid will require common communication
standards, billions and billions of dollars, and fundamentally
new ways of thinking on the part of us all. But the
overwhelming impression I took away is that there is a
tremendous amount of low hanging fruit for early players topluck. The market is evolving. There are signs of intelligent
life on the grid.

The Smart Grid and the Advance of CivilizationMichael Giberson |Center for Energy Commerce, Rawls College of Business,
Texas Tech University
2Scientic American has an article on the start-up pains
associated with smart grid development:
Only one thing is worse than the lights not coming
on when the switch is ickedand thats the lights
going out right afterward. The fact that the problem is
most often a burned-out lightbulb is testimony to the
reliability of whats sometimes called the worlds largest
machinethe U.S. transmission and distribution grid
for electricity.
This made me laugh:
If Alexander Graham Bell returned to Earth today, the
progress in telecommunications over the last 125 years
would be mystifying, said Robert Catell, chairman of
the New York State Smart Grid Consortium, at a smart
grid event in New York City at New York University
(NYU) in February. If Thomas Edison came back today,
not only would he recognize our electricity system, hecould probably x it when problems arise.
Probably not true. After all, most of the grid is based on
alternating current (AC) technology, but Edison was a
proponent of and best understood direct current (DC). Now
if Catell would have said Nicolai Tesla, that would have
been both funny and true.
The article mentions many trials and early advanced
metering programs, emphasizing the costs and uncertain
benets. Catell is quoted again, saying, An educated
and informed consumer is the best weapon in the war
against energy demand, and the smart grid is the best way
to educate the consumer. Some of the examples in the
article have benets coming from having consumers act in
response to information provided (via the meter, email and
even an in-home orb that glows different colors depending
on the price of power).
But engaged, immediate consumer response to changing
prices is likely only to play a small part within the bigger
energy picture. People (who are not energy policy geeks
or early adopters) have too many other things to do. As
Alfred Whitehead said of civilization generally, consumer
engagement in the electric power industry will advance by
extending the number of important operations which we
can perform without thinking about them.

Since its been all-too-quiet on the EEStor front, I gured
Id at least draw attention to the companys latest
atent approvalthis one titled Systems and Methods for
Utility Grid Power Averaging, Long Term Uninterruptible
Power Supply
A link to the patent, which was just approved a few days
ago by the U.S. patent ofce, can be found here at the
TheEEStory.com. EEStor and ZENN appear to be in complete
lock down no information is owing from either. Ivebeing hearing chatter in the investment community that
EEStor has run into some technical (not nancial) trouble,
but then again, Ive been hearing this kind of chatter for
the past few years since I wrote my rst feature on the
company in the Toronto Star. I tried to arrange a visit to
EEStors headquarters in Cedar Park, Texas, for some time
this summer. I wanted to gather some information for a
book Im working on that will be released next fall, but
Weirdespite my offer to sign a non-disclosure wouldnt
allow it. He wished me luck and said he doesnt want orneed the attention. (The book, by the way, isnt just about
EEStor, but EEStor will represent a chapter in it. The book
will be about barriers to energy innovation stay tuned).
Fair enough.
The explanation in the patent of how an EESU could benet
the grid is pretty straight forward, so this is really no
surprise. But its nice to see the company beginning to
accumulate a sizable stockpile of patents to protect its
IP. Despite the silence out of Cedar Park (and Toronto), I
do nd it interesting that there are some other ventures
hot on EEStors heels, just as Weir was expecting. On April
29, for example, the U.S. Department of Energy announced
funding as part of its ARPA-E program. One recipient of
funding was venture spun out of Penn State University
called Recapping Inc., which received $1 million.
Recapping Inc. and researchers at Pennsylvania State
University will seek to develop a novel energy storage device
based on a 3D nanocomposite structure with functional
oxides that provide a very high effective capacitance. The
basic fabrication of the dielectric materials and devices will
utilize traditional multilayer ceramic fabrication methods
that will provide a cost-effective alternative to battery
solutions, with the added benets of exploiting mechanisms
that could maintain higher cycling and possibly deliver
charge with high power density. This technology hopesto create a cyclable and economically competitive energy
storage device that will catalyze new, related cleantech
industries and contribute to the reduction of greenhouse
gases and oil imports, according to the DOEs description
of what Recapping is doing. Notably, whos the only
executive of Recapping Inc.? That would be Alex Kinnier of
Khosla Ventures. I tried to contact Kinnier, who wouldnt
talk but said to come back in 12 months.

My blog dated April 19 focused on PG&E activities that
seemed to be designed to kill the spirit and the objectives
of the Smart Grid. Since then, PG&E has admitted that
mistakes were made in some meter installs (although my
PG&E smart meter functions perfectly, thank you very
much), the tariff change is wending its way through the
regulatory process, and California voters decided the fate
of Proposition 16. This proposition was sponsored and
funded by PG&E. According to the latest news reports, PG&E
spent $46 million on TV, newspaper, and print media adsextolling the virtuesin PG&Es viewof voter-protected
monopoly power. The vote breakdowns make it clear that
PG&E lost in its own territory of Northern and Central
California. It scored more votes per dollar in territories
served by Southern California Edison and San Diego Gas
and Electric than in its own backyard. Rumor has it that
even PG&E employees hated the measure.
Was this evidence of a smart meter backlash or a simple
demonstration of that adage that familiarity breedscontempt? Only detailed surveys will determine that, but it
is clear that PG&E needs different advisors in the executive
suite and a fresh approach to interacting with customers.
So, community choice is safe in California, and this is
excellent Smart Grid news for two reasonsbut theres a
real warning in the poll results too. (Community choice lets
cities, counties, or neighborhood entities purchase and/or
generate electricity for residential and business use within
their boundaries. Community choice means local control
over energy resources, more renewable sources of energy,
plus a lower overall cost of electricity.)
First the good news. Community choice should accelerate
the integration of sources of renewable energy into the
grid. As the environmental devastation grows from oil spills
(even on landsee the Red Butte Creek spill in Utah), it
is becoming apparent to even the most oblivious that thisis one fossil fuel that we would be well-served to render
obsolete. For instance, communities can band together to
create solar gardens and aggressively convert rooftops to
solar power to generate local clean and renewable power
for their electric vehicles.
A second benet is that distributed generation improves
our grid security. Complete reliance on centralized energy
generation puts all eggs in one basket. If you believe the
reports about hackers inltrating the computer networksthat control the electrical grid, or even if you only believe
a fraction of them, theres serious reason to be alarmed and
deploy solutions that improve the stability and reliability
of the electrical grid. A grid studded with microgrids and
CCA-controlled energy sources is a smarter grid, less likely
to be completely disabled and able to recover faster from
natural disasters or acts of criminality and terrorism.

However, there is a real worry in the Proposition 16 results.
It is clear that PG&E customers dont trust PG&E. Thisdoes not bode well for future PG&E efforts to educate
their customers about TOU (Time of Use) rates and other
measures to reduce electricity needs at peak time periods
to save money and reduce carbon emissions. Enlightening
consumers about their energy use and encouraging
participation in smart energy programs is a process of
complex messaging, and it requires a relationship of trust.
PG&E doesnt have that now, and the big question iscan
they earn consumer trust to be effective in their future
Smart Grid solution rollouts? If they fail in that endeavor,we all lose.

Proxy Demand Response (DR) is a creative program that can
be used to offset the need to build expensive peaker plants
and help with the management of renewable sources of
energy that are intermittent in nature, like wind and solar.
While the wholesale market has been operating in other
states and later this year in California, the retail market
has barely been accessed, due to several factors. First, it
represents a smaller chunk of electricity consumption than
Commercial and Industrial (C&I), and naturally utilities
and third party aggregators focused on the low-hangingfruit. Second, the recent arrival of Smart Grid technologies
only now offers opportunities for uti lities to consider mass
residential deployment and participation.
Smart Grid technologies such as robust Home Area Networks
(HANs) and Home Energy Management Systems (HEMS)
come into play here to communicate information about DR
events as well as dynamic pricing programs for residential
responses. Third, the vast majority of residential consumers
or ratepayers are completely unaware of these programs,their processes, or their benets. And its difcult to
communicate anything about DR in a sound bite, much less
a Proxy DR program.
There have been some limited residential DR programs here
in California aimed at air conditioning (AC) cycling, but
these involved targeted groups of ratepayers and required
special equipment to remotely control residential AC units.
Utilities are now looking at much more ambitious programs
that impact most ratepayersin the form of new pricing
programs that more accurately reect the time component
of electricity generation. The average Joe or Jane Ratepayer
would be surprised to learn that generation of electricity
has different costs at different times since this is not
typically reected in their current bills.
Education is one of the three big challenges to implementing
wide spread DR programs for residential use. It will take
time to communicate carefully developed messagesthat build the foundation of knowledge for residential
ratepayers to appreciate the price variations in generation
and the benets of DR and dynamic pricing. They will need
exposure to messages like this one offered by CAISO in
their December 2007 eGrid Technologies Help Achieve
Environmental Goals report, Demand reduction is just as
effective, and often less expensive, than adding megawatts
onto the grid and it doesnt add a single pollutant.
The second challenge focuses on the business model.Proxy DR for residential participation requires new business
entities called Demand Response Providers (DRPs)
enterprises that can aggregate enough consumers to
represent the amount of electricity that can be bid into the
retail market. There are a few businesses operating in this
market, but they are relatively new to the space, and there
is much to learn about how to set up the most efcient and
protable model.

The third challenge is technological. Consumers will need
robust and reliable HANS and easy-to-use HEMS applicationsto participate in DRP programs. Their HANs must reliably
communicate price signals and/or DR alerts to enrolled
devices that can either automatically shut off or reduce
their electricity use. The HEMS applications must be simple
to use to achieve the widest possible consumer adoption.
One of the most interesting HAN technologies that promises
that robustness and reliability is the Open Source Home
Area Network or OSHAN. Stay tuned next week for some
more information about it.

Jon Wellinghoff is the Chairman of the United States
Federal Energy Regulatory Commission (FERC)the FERC
is the agency that regulates the interstate transmission
of electricity, natural gas, and oil. As such, the FERC was
the agency which Google Energy applied to for its licence
to buy and sell electricity on the wholesale market,
for example.
Shortly after his appointment as Chair of the FERC in 2009
by Barack Obama, Chairman Wellinghoff made headlines
when he said
No new nuclear or coal plants may ever be needed in
the United States renewables like wind, solar and
biomass will provide enough energy to meet baseload
capacity and future energy demands.
A chance came up recently to have him on this show, so I
obviously jumped at it!
We had a great chatso good, in fact that I turned it into
two shows rather than edit any of it out.
