                                      Project Scope and Status
GVEA is a rural electric cooperative serving more than 90,000 residents across 5,000+ square
miles centered on Fairbanks, Alaska. The extreme climate of the region, with an average winter
temperature of
-50ºC (-58°F), makes reliable power an essential requirement for the local population.
Traditional means of providing reserve power, including constructing and maintaining additional
transmission and generation capacity, are costly under these operating conditions. Moreover,
the relatively small capacity (800 MW) of the Railbelt power network—which snakes through a
narrow corridor running from the Kenai Peninsula on the southern coast of the state to
Fairbanks in the center (an area that is home to the majority of Alaska’s population)—coupled
with its large geographical expanse, makes the region sensitive to changes in available
generation or shifts in load. The loss of a single 300-MW generator can, for example, have a
significant impact on grid stability.

Fairbanks, in particular, has suffered from power stability issues because the town draws half of
its power from a single long transmission line running from Anchorage in the far south. The
relatively remote location made extensive spinning reserve resources prohibitively expensive,
leading GVEA to adopt a shed-in-lieu-of-spin (SILOS) approach, which entails shedding loads in
response to rapid changes in frequency caused by loss of generation, until backup diesel
generation can be started and brought online. Because this approach produced substantial
inconvenience to its customers, GVEA sought alternative ways of providing spinning reserve
and emergency frequency support to the transmission system, including energy storage
systems.

Studies performed in the early and mid 1990s showed significant dynamic benefits to placing an
energy storage facility in the Alaska Railbelt region. Following these studies, GVEA opted to
build a BESS to provide spinning reserve and frequency stabilization for the Fairbanks area.
The BESS was intended to operate in a full power circle, allowing it to inject or absorb real

1st commercial CAES plant, operational since 1978. The 290-MW plant utilizes nuclear-sourced
night-time power for compression and produces peak power during the day via a natural gas
turbine. The facility stores the compressed air in two "solution-mined" salt caverns which
comprise a total of 310,000 cubic meters. (Water was pumped into and out of a salt deposit to
dissolve the salt and form the cavern.) The depth of the caverns is more than 600 m which
ensures the stability of the air for several months' storage, and guarantees the specified
maximum pressure of 100 bar. One cavern is cycled on a diurnal basis. The second cavern
serves as a black start asset if the nearby nuclear power plant unexpectedly goes down.
The 2nd commercial CAES plant, in operation since 1991. Like the Huntorf plant, the McIntosh
Unit 1 facility stores compressed air in a solution-mined salt cavern. The cavern is 220 ft in
diameter and 1,000 ft tall, for a total volume of 10 million cubic feet. At full charge, the cavern is
pressurized to 1,100 psi, and it is discharged down to 650 psi. During discharge, 340 pounds of
air flow out of the cavern each second. The cavern can discharge for 26 hours. The plant also
utilizes nuclear-sourced night-time power for compression and then produces peak power
during the day by releasing the compressed air into a 100-MW gas-fired combustion turbine
built by Dresser Rand. The turbine unit also makes use of an air-to-air heat exchanger to
preheat air from the cavern with waste heat from the turbine. The waste heat recovery system
reduces fuel usage by roughly 25%.

Installed for UPS at STMicroelectronics Wafer Fabrication Plant in Phoenix, Arizona in 2000.

The two-year test program was designed to assess the plant capabilities, to learn more about
battery system operation in a utility network, and to examine methods of optmizing system
efficiencies.
Metlakatla is a remote Alaskan community on Annette Island accessible only by boat or float
airplane. Its small, stand-alone utility, Metlakatla Power & Light (MP&L), has historically been
able to reliably serve approximately 800 residential customers and a handful of commercial
customers via four rainfed hydroelectric generation units totaling 4.9 MW. In 1986, however, the
island’s largest industrial customer, Annette Hemlock Mill, began to cause power disturbances
for MP&L with the purchase and operation of a commercial wood chipper. MP&L’s hydro-
powered system could not sufficiently address the ~500 kW in load swings caused by the
chipper. Despite adequate generation capacity to cover the increased load, hydro response
time of 10 seconds proved too slow to follow the load swings, which occurred in about 0.05
seconds. Insufficient generation output caused brownouts and blackouts, and excess hydro
generation caused overvoltage.

In an attempt to solve the problem, MP&L purchased and installed a 3.3 MW diesel generator in
1987 for $2 million. But even with the diesel generator system instability continued. Moreover,
the operating costs of the diesel genset were expensive: roughly 475,000 gallons of diesel fuel
were consumed each year, all of which had to be transported by barge to the island and
pumped from the shoreline to on-site storage tanks.

To help mitigate the network’s instability in a more financially viable way, MP&L invested in one
of the first MW-scale lead-acid battery energy storage systems (BESS) in the United States.
The BESS unit was purchased and sited at MP&L in 1996 and commissioned in February 1997.

CEMC continues to use the battery facility for the coincident peak shaving. The batteries have
pass the 8-year mark (as of 1993) and are expected to last more than 10 years. Project update
required.

The BEST facility test was the first major utility-scale battery project in the U.S. since the early
days of utility systems. The project represents a milesone in U.S. battery development and led
to such projects as the Chino facility with 20 times the power output.

The battery plant runs basically unmanned, with remote control and monitoring. The only
maintenance requirement is periodic watering of the batteries. In addition, battery capacity tests
are performed annually. The plant ran in this mode for the first three years. In the fourth year,
battery cell failures increased consierably. Over the four years, 126 battery modules (5 cells
each), about 1.8% of the battery cells, failed. Failure was defined for an operating battery
module when the temperature of one cell exceeds 55 degrees C while other cells remain below
40 degrees C. Most failures were traced to the automatic watering system. Some battery cells
were drying out and losing capacity because they were not being filled properly. The solution
was to add additional electrolyte level indicators to use with the watering system. The new
indicators are checked manually to verify that the watering system is working correctly.

The Hawaiian Electric Company (HECO) is using ESA ultracapacitors to mitigate fluctuations
arising from intermittent generation at a 4-MW wind farm. These fluctuations present a
particular problem on the small grid on the Big Island of Hawaii, where wind power generation is
relatively large compared to the total installed generation capacity, and is particularly large with
respect to the available regulating reserve.

Ultracapacitors are high-power energy storage devices that make up for their relatively low
energy storage density with very high cycle life and power capabilities. A small ultracapacitor
installation can deliver a large amount of power, albeit for a small period of time. It can also
absorb power quickly. These characteristics make this technology attractive for buffering short-
duration fluctuations in wind turbine power output as they can produce a smoother, more
regular power output. This application is analogous to that of a shock absorber that buffers
mechanical vibrations -- hence the name of the product, the Electronic Shock Absorber (ESA).

HECO has commissioned an ESA unit for a 4-MW wind farm on the Big Island. The prototype
unit, designed and constructed by S&C Electric Company, is sized to deliver up to about 500
kW for up to 7 seconds. The power injection significantly reduces the ramp rate of the wind




The result of the assessment was the decision to install battery storage plants in the PREPA
system. PREPA accepted bids for the battery and converter from C&D Batteries and General
Electric, respectively, in mid-1991. Field construction began in August 1992. Start-up in
October 1993. It is no longer in commission after ~5 years of operation.


Commissioned in Jan 2005 and operated thru Jan 2008, the VRB system was attached to the

AEP has pioneered the use of NaS batteries in the United States. Following testing at its Dolan
Technology Center near Columbus, OH, the utility became the first U.S. electric company to
deploy NaS batteries in 2002 when it installed and operated a 100kW/500kVA demonstration
unit in Gahanna, OH. In 2006, AEP installed a 1.2-MW stationary NaS battery near Charleston,
WV. And in 2008, the utility installed three, 2-MW NaS batteries: one in Churubusco, IN.; one in
Milton, WV; and one in Bluffton, OH. The 7.2 MW in NaS deployments are part of AEP’s
electricity storage strategy that will also include transportable stationary batteries and distributed
small scale energy storage systems.

AEP deployed all of its NaS installations as a means to provide load leveling and alleviate
transformer loading during summer peaks, defer capital upgrades, and offer emergency backup
power to several hundred customers during electrical system outages. Ultimately, the NaS units
offer AEP a degree of flexibility in determining the optimal approach for handling reliability
problems. The units buy the utility time to decide whether to redesign a substation, build
generation, or keep the storage units in place permanently. (All of the NaS systems are capable
of being relocated for an estimated $85,000 to $115,000 if and when the company’s needs for
storage change.)

One 2-MW unit was originally intended to improve wind energy integration in the utility’s Texas
service territory and to generate revenue as a wind-gas price arbitrage tool. However, these
plans were postponed because of additional costs associated with directly linking the battery
unit with a wind plant. The batteries can also be used for grid frequency regulation, though AEP
has not yet pursued this application.

AEP’s initial 1.2MW/7.2MWh NaS battery project was commissioned at a Charleston, WV,
Anaheim PUD’s two-year pilot project is testing a 50-kW Li-ion energy storage system. It has
been operating since June 2009. Two solar PV systems totaling 75 kW feed power into the
energy storage system, and during peak electricity usage periods the storage system
discharges the power into the grid. The utility would like to offer incentives to customers who
install solar systems to also install energy storage systems. Customers would be encouraged to
dispatch stored energy when called upon by the utility.

During the pilot phase, the utility will be evaluating the dollar value of the $100,000 energy
storage system in terms of the savings it brings to the utility. iCel’s 50-kW energy storage pack
is installed at Anaheim PUD’s pilot project. Operating since June, it contains a pack of 50
lithium ion batteries with a parallel architecture and physically integrated circuitry. It can
simultaneously charge and discharge energy and provides 50 kWh of energy storage. Ryan
Wartena, iCel’s chief technology officer and designer of the system, says the prototype three-
phase system operates at 24 volts DC and 480 volts alternating current (AC), and is fully
After the first year-and-a-half of operation, about 340 cycles, tests were performed on randomly
sampled batteries. The tests indicated that the batteries maintained at least 80% of their
original storage capacity. Tear-down of these batteries revealed evidence of some sponge lead
on the negative plates, some plate expansion, and evidence of electrolyte stratification. After
the first two years of operation, about 400 cycles, the total maintenance of the system consisted
of the replacement of nine batteries (0.8%) for internal shorts, and an equalization charge to
reduce the stratification of the electrolyte by gassing.

The following is typical of the average month's operation, based on two years' experience:
· Number of discharges: 17
· Depth of discharge: 25%
· Peak reduction: 210 kW
· Rate of discharge: 230 kW
· Discharge energy: 307 kWh
· Charging period: 1.27 h
· AC-AC turn-around efficiency: 74 - 86%

This project tested the application of a Premium Power 'PowerBlock 150' zinc-flow battery
installed and operated in an electric distribution system. Project update needed.
The goal of investigations of battery energy storage (BES) systems was to provide lower electric
costs to the customer, as well as utility benefits from peak-load shaving and relief from
minimum load conditions on the system.

The demonstration project had the following objectives:
· Demonstrate the key features of BES systems
· Assess BES benefits for both customer and utility
· Evaluate VRLA battery technology for customer peak-shaving applications
· Evaluate the insulated gate bi-polar transistor (IGBT) power conversion technology for small
customer-owned BES plants
· Evaluate the feasibility of commercially available, off-the-shelf control systems
· Assess reliability, safety, environmental acceptability, and flexibility of BES plants




80 kW x 15 minutes
All buses in the LI Bus company system are powered by compressed natural gas (CNG) and
fueled at a centrally-located fueling station that utilizes four compressors to compress natural
gas. Three of the four compressors are powered by electricity supplied by LIPA, while a fourth is
natural gas-powered via a local gas line. To reduce its steep, on-peak electric charge, LI Bus
historically operated a third shift during nighttime, off-peak hours when utility demand charges
were nil. This approach produced electricity cost savings but also incurred additional labor
costs. Consequently, LI Bus has pursued a battery energy storage project—funded by a broad
consortium of stakeholders, including EPRI and its members, NYPA, NYSERDA, US DOE,
LIPA, and LI Bus—with the following four goals:

1. Achieve cost savings via the elimination of the third shift required to perform fueling without
incurring peak demand charges (accomplished via off-peak battery charging and daytime
fueling);
2. Increase back up power for the bus fueling to meet a regional emergency response plan;
3. Reduce peak demand on the heavily loaded utility grid through managed time-of-use and
peak shifting; and
4. Demonstrate long term, commercial operation of a high efficiency peak shift energy storage
system.

The battery project effectively began in mid-2004 with the awarding of a $1 million grant by
NYSERDA to NYPA and LI Bus; stakeholder meetings ensued through the end of 2004. During
this time, NYPA, working with EPRI, determined that a battery energy storage system (BESS)
would be best suited for the project’s proposed managed time-of-use application. (Microturbines
and reciprocating gas engines were initially considered, but were not pursued due to long-term
natural gas price uncertainties, generation-related emissions, and the explicit preference by
LIPA for an energy storage solution to on-site electric generation.) To this end, a number of
battery technologies were reviewed, including those composed of zinc-bromine, vanadium
redox, sodium sulfur, and polysulfide bromide chemistries. Of these, only NaS batteries had a

After four years of operation, the lead-acid batteries cycled approximately 900 times and have
met or exceeded expectations. Scheduled system tests have measured basic system
performance, controllability of operation, reliability, and environmental effects. Following are
some test results:

Battery capacity has dropped to about 82% of the original capacity but is still within acceptable
limits
AC-AC efficiency, including auxiliary losses for the 1 MW, 4 hour discharge and charge is 68%
and the battery efficiency is 81%, slightly loqwer than the original AC-AC efficiency of 73% and
battery efficiency of 85%.
Auxiliary power (building, etc) is only 0.3 to 0.5 percent.
System efficiency improves at lower discharge and recharge rates.
It is more efficient to start the battery at 90% charge and use electrolyte agitators than to charge
the battery to 100% in order to mix the electrolyte by hydrogen bubbling.
Battery self-discharge is ~0.2% per day adusted to 25 degrees C.

Tests at Tatsumi have revealed other important characteristics of the system. For wexample,
the battery system can be used for grid voltage regulation and frequency regulation for spinning


A VRLA (valve-regulated lead-acid) battery system was installed at the GNB Battery Recycling
Facility in Vernon, CA in 1995. The BESS at the Vernon smelter consists of two strings of 378
modules each of 4800-Ah Absolyte batteries (9600-Ah on site). As of the late-1990s, it was
being used to peak-shave at 3150 kW on weekdays during peak demand times.
As of FY03, the BESS's batteries had reached an age where it was desirable to do more
extensive monitoring of their condition and operation to determine whether life expectations
were being met. A contract was placed to continue monitoring battery performance. In addition,
periodic postmortems of modules returned to GNB from the Vernon location were resumed to
assess how much degradation had occurred and estimate the remaining battery life.

The Vernon batteries have passed the end of their warranty period.
Xcel Energy is the number one wind power provider (predominately through PPA) in the United
States. With a large penetration of wind already in the utility’s balancing footprint and plans to
add more in the near future—a partial result of Minnesota’s 30% by 2020 RPS mandate—Xcel
has embarked on a Wind-to-Battery (W2B) Project to test and evaluate the effectiveness of
utilizing a large-scale NaS battery to facilitate grid integration of wind energy and, in turn,
mitigate system impacts of variable generation. Xcel initiated a pilot project in October 2008
with the siting of a 1-MW sodium-sulfur battery next to an 11.5 MW wind plant in Luverne, MN.

Project participants selected the NaS technology reasoning that it has a high energy storage
capacity, can handle a large number of charge/discharge cycles, is capable of dynamic
operation, has demonstrated commercial performance and availability, and is capable of near-
term large scale deployment. Meanwhile, deployment of the battery near the 11.5 MW wind
plant was pursued to allow the utility to avoid potential latency issues when trying to relay output
data from the wind turbines to the battery. This arrangement also allowed project stakeholders
to minimize land purchase and usage fees because Xcel Energy already owned a switching
station at the site. Finally, Minwind Energy, the wind plant owner, offered the use of its
interconnection transformer to the transmission system, which enabled Xcel to avoid the need
to purchase and register an additional transformer.

Research objectives of the utility pilot, the first attempt in the U.S. to utilize a NaS battery as a
direct wind energy storage device, included:

• Evaluating the battery’s ability to firm wind energy and effectively shift it from off-peak to on-
peak availability;
• Evaluating the distributed energy storage system’s (DESS) ability to reduce Xcel Energy’s
need to compensate for the variability and uncertainty impacts of wind against other grid
balancing procedures;
• Evaluating the optimal ratio between energy storage and total wind capacity that would allow
the wind energy storage system to be a more attractive peak-load resource;
• Evaluating the potential for battery technology to provide ancillary service support (e.g.,
reactive load support, spinning reserve, frequency regulation, contingency reserve);
• Assessing the obtainable value of storage in the Midwest ISO (MISO) market for several wind
penetration scenarios; and

                                        Results & Findings
The GVEA BESS was commissioned on June 19, 2003 and formally inaugurated in August
2003. It saw its first real discharges beginning in November of that year. During commissioning
tests the ABB power conversion system and the Saft battery set an unofficial world record by
achieving a peak discharge of 26.7 MW, while providing -37 MVAR (inductive), with two strings
operational. Data indicates that the power performance of the BESS has exceeded
specifications with 27 MW supplied for 24 minutes with two of four strings. Two more strings
came online on December 10, 2003, providing 46 MW of power.

GVEA has installed substation hardware and the necessary SCADA programming to use the
BESS Auto Scheduling mode. In this mode, GVEA monitors the status and megawatt flow
through remote generator and transmission breakers and, in turn, provides the information to
the spinning reserve and contingency applications running on GVEA’s SCADA master station.
Those applications determine what the output of the BESS should be on a moment-by-moment
basis if one of the monitored breakers goes open. Information is sent every second to a breaker
status table running in the BESS HMI. GVEA monitors the trip coil circuit at each breaker and
the BESS uses the status table to ramp up its output to the required megawatt value. Because
of the speed of the communication system and the fact that GVEA is not waiting for the contact
at the breaker to change state, operators are able to inject power into the system as the breaker
is opening. As a result, rather than waiting for system frequency to decline and then having the
BESS respond in a spinning reserve fashion, GVEA proactively reacts to a coming breaker trip.

The BESS is very quiet from a broadband interference standpoint. EMI measurements from 500
kHz to 2.0 GHz revealed very little additional noise being added to the background noise level.
Harmonic measurements taken to determine the background levels and then again at various
output levels, have shown that the BESS meets the IEEE 519 recommendations for voltage and
current harmonics. This is good endorsement for the IGCT converter technology employed by
ABB.




The turbine unit can provide up to 890 MWh of continuous power. It is utilized primarily as a
capacity reserve unit.
Compared to conventional combustion turbines, the CAES-fed system can start up in 15
minutes rather than 30 minutes, uses only 30% to 40% of the natural gas, and operates
efficiently down to low loads (about 25% of full load). The key function of the facility is for peak
shaving.
During the two-year test program, the Chino facility successfully operatied under the following
utility applications:

Load-leveling
The plant proivded up to 43 MWh over a constant-pwoer, four-hour discharge.

Load-following and T&D deferral
The battery system was used to reduce the actual peak load on the 12-kV bus. During peak
summer loads, the 12-kV bus exceeded transformer ratings. Upon operator-entered set-points,
the battery system was programmed to help reduce the load on the 12-kV bus as needed.

Frequency Regulation
Tests demonstrated the battery plant's capabilities to compensate for rapidly changing power
flows on the grid and limit the requncy excursions.

Voltage/Regulation power control
The battery plant demonstrated the capability of supplying real and reactive power to the grid.

Black-start operation
The Chino facility successfully completed a black start operation test, which included supplying
pwoer to a de-energized utility line.




After six months of operation, the system still required occasional adjustments to the controller.
The early results of its performance indicate that this system can be matched to a specific utility
demand schedule and used to effectively shave peak-power demand. The foundry's on-peak
energy demands are significantly reduced. The system automatically follows the energy
demand by supplying or delivering energy to the foundry operation, including the use of on-peak
or opportunity charging. This type of charging is done during periods of low power demand and
effectively extends the capability and life of the battery.

Total harmonic distortions (THD) proved to be better than initially anticipated. During discharge
at 280 kW, the THD for the voltage was measured at 1.4%. In charge mode, the measured
value was 1.3%. Two unplanned local power outages have successfully tested the abilities of
the fault protection system. The accuracy of the battery sizing program has been verified with
most cycles running the battery to a 70-75% DOD as compared to an 80% target level.

The JCI turn-key energy management system can provide automatic peak shaving
performance that can lower monthly electrical demand charges by as much as 50%. The
system can be built to the customer's needs and adjusted as their utility demands change.
During the first two years of its operation, the BESS was primarily used to help offset grid
fluctuations created by the Annette Hemlock Sawmill (which closed in 1999). During this period,
the BESS was able to mitigate load swings and the diesel generator was nearly taken out of
service altogether (it is now available as an emergency backup generator and for charging the
BESS). Consequently, the BESS was able to offset the cost of 475,000 gallons of diesel per
year and also lower transportation costs and costs associated with periodic maintenance of the
diesel generator.

In addition, by controlling the BESS to charge and discharge in response to load swings, system
frequency was able to be maintained at much tighter tolerances while giving adequate time for
the hydro units to react. The battery was kept at about 90% state-of-charge to provide capacity
to either absorb or generate real power to the grid. From this state-of-charge, roughly 1.1 MWh
was able to be utilized as reserve power in the event that one of the hydro units were to trip
offline unexpectedly.

With the federal ban on logging in the Tongass National Forest, effective January 2000, the mill
discontinued operation two years after the installation of the BESS. As a result, the original
problems associated with the mill’s load swings are no longer an issue for MP&L. Still in
operation today, the BESS continues, however, to run charge/discharge cycles on an everyday
basis. The battery has not been offline since its commissioning except for scheduled
maintenance and repair.
The availability of the battery plant has exceeded 85%. The main unavailability periods are
during intermediate and equalizing charging. For the first three years of operation, BEWAG
calculated an annual savings of $7,400,000 (US equivalent). In the fourth year, the calculated
savings was about $7,100,000 due to increased maintenance and battery replacements. These
savings can be favorably compared to an initial plant cost of $14,000,000. BEWAG was
surprised to find that spinning-reserve savings were greater than savings from load-frequency
control.
• The installation of the VRB inproves the line voltage on the 25 kV by 2.2% (Combination of
250 kVar and 250 kW)
• Reduced capacitor charging during losses and Line losses will amount to about 40 kW in
reduced power demand. This more than offsets the parisitic losses of the VRB-ESS
• Worst case voltage variation tha twill occur when the VRB-ESS trips off line during maximum
load and when the VRB-ESS was providing maximum power support, will be 4.6% (this has not
been measured during peak season).
PREPA found that battery storage was the most economic alternative for rapid spinning reserve
to eliminate automatic load shedding. CTs would also serve this function, but cost considerably
more. In addition, battery storage was the only technology that could improve spinning reserve
and voltage stability. PREPA estimated an additional savings of $10 million by using batteries
to reduce transmission losses and substitute SVCs for voltage future stability.
1.2 MW unit
The 1.2 MW NaS DESS at Charleston has performed successfully for three summer peak
seasons. During its first year of operation, the unit was available 90% of the time for its
scheduled daily discharges. It experienced a total of 38 days of unscheduled down time, due
mainly to PCS failures and a change in metering of pulse-like battery heater load.

Over its first three years of operation, the unit improved the feeder load factor by 5% (from 75%
to 80%). It also reduced the oil temperature of the transformer by ~4C.

2 MW units
The three 2-MW installations put into service in 2008 have been successfully performing peak
shaving on an ongoing basis.

In addition, the unit sited at the Balls Gap substation in Milton, WV successfully islanded
approximately 700 customers for roughly 30 minutes during a simulated outage staged on July
8, 2009. A live islanding event, meanwhile, took place in December 2009, during a snowstorm
that islanded 25 customers for two days. Over that period, the Milton installation was able to
minimize disruptions; customers experienced less than three minutes of continuous disruption
during the two-day outage period.

Finally, on October 20, 2009, the Milton, WV battery was successfully operated to alleviate load
and voltage concerns during a load transfer event between substations. While the transformer
at one station was taken out of service for maintenance, load was transferred to a different
station which caused voltage and loading concerns. The Milton battery was deployed and
mitigated these concerns.
According to 1993 data, the project has not yet provided definitive results on whether or not the
automotive battery is suitable for use in peak-shaving systems. The project continues to show
great promise and has had positive results in shaving the plant's peak utility use, but the life
expectancy of the batteries is not yet known. The experimental system has met all of its early
expectations, and has required very little maintenance.
Technical specifications for the battery and PCS were developed using experiences from earlier
BES projects as well as vendor interviews. These specifications include:

Battery - A VRLA battery was selected because the VRLA cells require less space and less
maintenance than conventional "flooded electrolyte" cells. Also, the cells have very low
emissions of hazardous gases. An important design feature of VRLA cells is that they do not
require the addition of water throughout their lives. The battery was specified to provide a 210-
kW DC constant power output for a two-hour discharge. A cycle life of 1,500 cycles and eight
years was required.

PCS - The PCS power rating was specified to be 200 kW AC continuous. A life of 30 years,
with nominal maintenance, was stipulated. The maximum reactive power consumption was
specified to be 97 kVAr under all operating conditions. The PCS was required to have a
maximum response time of 20 milliseconds to a 10% power level step charge, and 200
milliseconds for zero to full power.

Control and Data Acquisition System (CDAS) - A commercial process control system, based on




The NaS BESS and ancillary equipment was successfully installed in late 2006, but
interconnection problems and battery failure delayed the facility’s commissioning until
November 2008. Following the resolution of continued nuisance trips and DAS problems during
December 2008, the BESS installation was put into commercial operation at the LI Bus site on
January 1, 2009. Until recently the BESS has operated as intended, silently powering three 600
hp CNG compressors used to fuel 220 CNG busses while providing load shifting capability for
the LI Bus refueling facility. Through September 23, 2009, it had completed approximately 351
cycles and could successfully eliminate the third shift. (For their own reasons, the LI Bus
Operations group has decided to run fueling from 6pm-2am—times that intersect with the third
shift—and, in turn, only realize partial returns from the BESS.)

A data acquisition system (DAS) supplied by US DOE (Enernex developed the software) was
designed to collect a data point roughly once per second, with aggregate data being uploaded
daily to a central server. Information gathered by the DAS includes AC and DC voltage, current,
energy, and power into and out of the system; battery state of charge, cycle count and
internal/ambient temperatures and conversion efficiencies; auxiliary loads and standby losses;
and operating state durations and response times to changes in operating conditions. A single
day of data can represent roughly 13 MB. Problems concerning DAS communication with the
PCS and NaS systems, however, prevented the BESS’s operation in 2008, and, following
additional issues, new DAS equipment is being installed by NYPA.

Several customer issues, largely external to the battery and PCS, have affected the
demonstration. Two of the more notable include:

• Higher than expected energy consumption and cost increases by the customer. Project
participants expected an increase in energy consumption and associated cost due to battery
inefficiency, but the increase has been greater than predicted. NYPA analyzed the potential
causes and found that measured DC-DC battery system cycle efficiency met or exceeded
The following benefits have been identified by investigations on the lead-acid battery system at
the Tatsumi Energy Stoarge Test Facility:

peak shaving
frequency regulation
voltage regulation
real and reactive pweor ocntrol (1 MW and 1 MV Ar)
fast power ramp-up (0 to 100% in <2 seconds)
spinning reserve
environmentally safe
unmanned, remote operation
high reliability
Following are preliminary results derived from 21 months of data gather and analysis.

The battery was able to effectively time shift wind energy from off-peak to on-peak availability.
Overall, the DESS performed as expected for the majority of scenarios tested. Project analysts
did find that a modification to the PCS software was required for one of the discharge profiles.
During the testing period, the 1 MW wind farm scenario was incapable of fully charging the
battery during the allowed charging window of 8.5 hours, while the 10 MW wind farm scenario
generated more wind energy than needed. Project analysts recommend additional testing,
especially at and around a 5-MW scenario, to better understand the optimal ratio of wind farm
capacity to DESS capacity for time shifting applications.

The DESS adequately responded to economic dispatch signals. The DESS followed set-points
based on an algorithm that uses forward and spot energy prices in the MISO market along with
settings from the user. (The battery was never offered into the MISO market; project analysts
instead estimated settlements results.) Although arbitrage potential was limited due to market
conditions, stakeholders aver that results can potentially be improved by optimizing the control
algorithms. Performing additional testing using different market nodes and pricing information
from previous years could better estimate potential financial returns over an extended period of
time at various physical locations.

Despite frequent temporary system alarms, the DESS performed well when following a
frequency regulation signal. The DESS followed a frequency regulation signal derived from
changes in the Area Control Error (ACE) for the MISO market. On a continuous basis, the
device followed the rapidly changing set-points issued by the NSP Energy Management System
(EMS) in a timely and accurate manner and displayed excellent ramping capabilities. Additional
testing is recommended to determine if any long-term battery damage is incurred as a result of
rapid and frequent battery charge/discharge.

Though test results measuring the effectiveness of the DESS to smooth wind output via ramp
rate control were mixed, the battery was successful in limiting the rate of change in a 1 MW
wind energy output scenario. Ramp rate control was tested by using a first order lag function to
vary the charge/discharge rates of the battery based on the output of the wind plant. However,
test results were mixed due to range limits in the PCS source code. The DESS was able to limit
                                       Lessons Learned

The BESS has, to date, experienced only minor problems related to materials and
maintenance—both of which have largely been resolved. Problems have, for example,
developed concerning the water injector strings. Each cell has one water injector string, which is
sealed to the cell with a gasket. Although the internal components of the injector are resistant to
the KOH electrolyte, they are not completely resistant to the cell oil that floats on top of the
electrolyte to prevent water evaporation. As a result, during heavy discharges or vigorous
recharges, cell oil sometimes makes it way into an injector, which eventually causes the injector
to either stick open or close prematurely. GVEA revised its module refilling procedure to check
each cell and manually verify that the injector is working correctly, and is working with
Philadelphia Scientific to correct the problem. GVEA expects to eventually replace all of the
water injector strings.

Separately, GVEA has learned to coax more megawatt-hours (20MW+) out of the BESS during
large spinning reserve events. The battery voltage declines during any event until either the
event is over or the battery hits the 1 VDC/cell limit (3,440 VDC). If the battery hits the 1
VDC/cell limit, the BESS automatically starts ramping down at 4 MW/minute. If the BESS is still
needed the dispatcher can arrest the decline at, say, 15 MW and sustain that level until the
battery once again reaches the 1 VDC/cell limit. This can be done 3-5 times during an event.
GVEA has been able to coax over 12 MWh out of the battery during some events.

In addition, GVEA dispatchers have been using the BESS in the AGC mode more than
previously anticipated and have been able to cover some morning and evening peaks.
Moreover, GVEA is triggering the BESS AGC mode to a preset level whenever the Alaska
Intertie between the Anchorage and Fairbanks grid goes over its operational MW import limits.
This happens automatically and allows GVEA to stay below grid stability limits without operator
intervention.
Overall, the Chino facility completed the two-year demonstration period meeting all of the
project goals. Project responsibility was then transferred within SCE from their research and
development to operations staff. Over the span of the project, a few problems were
encountered and handled. Druing a heavy rainstorm in December 1988, water leaked through
the roof, causing a short circuit in a DC-ebntrance cabinet to the PCS for one battery string.
The partial range fuses on the postiive battery leg failed and provided a ground fault. A flash
fire resulted, causing minor damage. The facility was shut down for three months to improve its
electrical safety and weather resistance.

In addition, over 300 cells developed leaking joints between the battery case and cover. In
December 1990, the battery manufacturer repaired the cell leaks on-site at no cost to SCE.
The battery watering system has been adjusted and upgraded several times to reduce the
associated manpower requrements and improve reliability. the PCS and battery controllers also
had numerous failures until it was determined that overheating on hot summer days was the
cause. Adding air conditioning units solved the problem. Finally, the PCS has shut down on
several occasions for GTO thyrister failure. This fauilure mode hadn't been well understood,
but the SCE miantenance organization had reduced down time for changing-out the parts to a
few hours.

Through 1993, SCE has been operating the Chino battery storage facility as a system resource.
The plant continued to meet all design and operation requirements.
Securing project funding was a major challenge. MP&L exhausted state funding assistance in
1987 when it purchased a 1 MW hydro unit with a $500,000 grant through the Alaskan
Department of Community and Regional Affairs’ Rural Utility Service. As a result, subsidized
rural utility rates provided via state programs were unavailable to the community to support the
project and its commissioning.

MP&L’s decision to use a different discharge testing plan than suggested by the BESS’s
operating specifications has not been problematic. As part of scheduled maintenance, the utility
runs annual equalizing tests on the BESS that entail a full discharge and full charge of the
battery system.

Though MP&L has been satisfied with the performance and reliability of its large-scale lead acid
BESS, technology advances have made it difficult to maintain the system. In particular, parts for
the 14-year-old inverter have become obsolete and are becoming increasingly difficult to
replace.
The battery plant has a much higher power gradient that a turbogenerator and BEWAG found
that the battery plant was used much more than anticipated for load-frequency control. The
daily capacity turnover was designed for 2.0 to 2.3 times the rated capacity. On hot summer
days, the turnover reached 3.5 times rated capacity. In order to avoid cell temperatures abouve
40 degrees C, the power output was reduced. To avoid this problem, BEWAG ran additional
tests on heat exchangers. Specifically, BEWAG found the inner cells of the 5-cell modules
were running up to 5 degrees C hotter than end cells. The heat exchangers were redesigned
for lower overall temperature operation and 1 degree C cell-to-cell temperature differences.
This is expected to eliminate the need for power reductions.

An earth fault in the grid system generated an overvoltage that harmed the thyristors in the
converters. The solution was to add voltage-limiting varistors to the converter damping
networks. A second earth fault occurred recently and the overvoltage protection functioned
properly.

• Though the collaboration between AEP, NGK and S&C resulted in the successful installation
of the DESS, AEP had to manage five different entities in multiple contracts and coordinate a
variety of tasks and schedules in order to complete the task. A single company should assume
the complete task of DESS delivery and system integration; and, in turn, this should be reduced
to a single contractual relationship between the utility and the DESS supplier.
• Battery module shipping should take into account that some cost components of shipping
charges are based on a ―per container‖ basis. Because initial plans for the Charleston unit
involved testing the PCS with NaS batteries in advance of completion of all 20 of the DESS
batteries, AEP ordered six modules to be shipped prior to completion of the entire system. As a
result, one container was partially empty, resulting in unnecessary shipping charges.
• On-site modifications of the battery enclosures was required to rectify differences between
Japanese and US manufacturing practices and standards, causing considerable delays. NAS
batteries cannot be stored outdoors while awaiting completion of the battery enclosures. And
storing them indoors might require permits. Unless the NaS batteries are delivered pre-installed
in integrated, relocate-able enclosures, it is necessary to closely coordinate battery delivery
schedules with the delivery schedules of the battery enclosures.
• The NaS battery offers the potential for greater energy savings. AEP utilized its battery at 83%
to 90% of its capacity to extend battery life. Applying PJM’s Locational Marginal Price (LMP)
data for AEP revealed that the DESS, with its existing daily charge/discharge schedule, could
have saved AEP approximately $57,000 during the first 11 months of operation, if it had been
utilized at 100% of its capacity. This saving could have been further increased if the daily charge-
discharge pattern were to be adjusted for optimum energy arbitrage, as opposed to actual
system capacity need.
• Insure NaS battery modules receive a proper number of burn-in cycles prior to leaving the
The following benefits can be associated with the use of automative batteries in utility load
leveling systems:
· Peak shaving
· Lower cost batteries
· System virtually maintenance free
· Minimal gassing during recharge
· Efficient battery recycling operations in place
A BES plant installed at the San Diego Trolley Grossmont substation would provide potential
benefits for both SDG&E and its customer, San Diego Metropolitan Transit Board (MTDB). In
simple terms, the benefits of BES from SDG&E's perspective would be to reduce capital and
operating costs of the electric system, while MTDB's benefit would be a reduction of its electric
bill, and provision of emergency power.




• Adequate specification of functional requirements is a must. Functional requirements for the
NaS system were not adequately determined by NYPA at project inception. Among the most
critical of these were the need for a wye grounded delta connection and the power requirements
for compressor start. In addition, NGK did not specify that its batteries must not be allowed to
stand for more than 10 hours in a discharged condition without appropriate heaters to keep
them hot.

• The NaS battery is suitable for its intended application, but the modules need initial ―burn in.‖
New NaS battery modules require nominal initial cycling (roughly six cycles) before shipment if
they are expected to be kept in hot standby for an extended period of time. This can help
mitigate potential issues that may occur as a result of delayed grid interconnection. The
project’s interconnection difficulties were a direct contributor to the failure of many of the battery
modules before the facility was even commissioned.

• Normal project delays can ―cascade‖ to major issues. For example, a grounding event
occurred during the summer of 2007 because of a miscommunication about the short-circuit
capability of the local feeder. As a result, NYPA had to re-perform the grounding study, adding
to project costs and causing a two-month delay, which further postponed cycling of the battery
(which had been kept in hot standby for six months in anticipation of connection to the grid and
commercial operation), and led to module failures. Replacement modules consequently needed
to be shipped and installed.

• The PCS units presented interconnection and operational problems, which can be resolved.
These problems were the result of a failure to properly specify system requirements and
understand site characteristics; equipment design and manufacturing inadequacies; extended
outage time during problems with the battery; and inadequate project team member
coordination. ABB’s PCS was a modified unit originally designed and UL approved for use with
a fuel cell. It needed to be re-designed for the battery and also obtain a new UL 1741
There have not been any major problems with the lead-acid battery system. The researchers
have made several recommendation to improve flodded lead-acid batteries over the design they
used in 1986. The recommendations focus on battery design, battery operation, and battery
room layout for better space utilization. The recommendations would increase battery energy
density, lower battery costs and improve battery life. The researchers determined that the
battery could be cycled from 100 to 20% charge, an increase over the originally conservative 90
to 35% cycling. This reduces the effective cost of the batteries.
• A DESS control system covering multiple modes of operation spans a wide array of skill sets
and requires an extensive amount of development time. An extensive amount of time was
required by project participants to define in detail various modes of operation. As a result,
multiple iterations to the PCS specification and control set-points list were required, and S&C
was delayed in beginning their programming tasks.

• Once designed, a PCS requires an extensive amount of programming time and a thorough
commissioning process. After the design specifications and control set-points list was finalized,
S&C started to program the PCS—a task originally scheduled to be completed within one
month. To minimize the number of errors encountered in the field, S&C constructed a control
test-bed and S&C and GridPoint performed lab-to-lab testing over several weeks to ensure data
connectivity between the two systems. S&C also performed in-house testing of the software to
minimize errors in the control logic. To verify the PCS operated according to the specification,
Xcel Energy generated a field commissioning document. During field testing procedures, project
analysts encountered multiple errors that were not originally identified during the lab testing
without the PCS.

• When defining a project test plan, it is best to identify only the most appropriate and/or
effective analytics approach for each value proposition in order to establish a plan that is
reasonable in scope and extensive enough to cover important research areas. Xcel Energy
worked with a number of analysts to identify multiple value propositions warranting investigation.
As a result, it was difficult for stakeholders to identify the most appropriate and effective
analytics approach for each value proposition. Furthermore, once project researchers identified
a method of analysis and began collecting data, additional time was required for data gathering
and analysis to adequately cover each value proposition. In addition to the multiple modes of
operation, project researchers encountered multiple errors in the datasets due to variety of
reasons ranging from user input error, communication outages, and unexpected PCS operation.
Each invalid dataset required project researchers to retest the battery, resulting in greater time
requirements.

• It would have been better to establish a central on-site data repository to collect data from all
the appropriate sources with uniform time stamps. For the project, GridPoint used the DNP3
protocol to collect and archive data, which project researchers then used in their analysis.

                                    Project Scope and Status


145-MW A-CAES Demo Plant; underground storage container: Solution Mined Salt Cavern

300 MW A-CAES demo plant will use an underground storage container (depleted gas/porous
rock reservoir), and next-generation turbomachinery. Still in RFP stage; vendors, utility
sponsors, and site locations not yet determined; Groundbreaking slated for 2011
ISEP is likely to become the world’s third CAES facility and the nation’s first to use an aquifer.
The project will use surplus electricity generated by a nearby wind farm to power a large air
compressor, which will compress air into a 3,000-ft deep well (the site will hold air at around
500 psi). Stakeholders hope that the ISEP facility will primarily convert variable wind resources
in the Iowa plains into a dispatchable resource. In addition to offering RE firming and energy
arbitrage opportunities, project participants also hope the plant will improve efficiencies of fossil-
fueled generation by allowing baseload units to operate for more hours near their cleanest and
most efficiently operating loads.

Construction delayed (originally scheduled for min-2009, with 2012 debut).
SustainX has committed to three project phases. Phase I is construction of a Pilot system
capable of 50 kilowatts (kW) of electric output, Phase II is construction of a 250 kW Demo
system, and Phase III is construction of a one-megawatt, four megawatt-hour (1 MW, 4 MWh)
energy-storage system to be demonstrated at an AES Energy Storage, LLC affiliated site. The
latter will be capable of storing enough energy to power 1,000 typical U.S. homes for
approximately 4 hours.


15-MW plant will use steel piping to hold pressurized air instead of geologic containers. Still in
RFP stage; vendors, utility sponsors, and site locations not yet determined; Groundbreaking
slated for 2011

The Norton Energy plant is being planned at a 340 million cubic foot abandoned limestone mine
in Norton, OH. The first round of the multistage project will produce a 200-MW unit that will
serve the bulk load shifting storage needs of two Midwestern utilities: American Electric Power
and First Energy. The mine is also located near the intersection of a 138kV First Energy
transmission line and a 765kV AEP transmission line. Additionally, the plant is intended to
provide ancillary services, including frequency regulation and spinning reserve, to the MISO
ancillary services market. Ground breaking is scheduled to occur before end-2010.
The nation's first grid-scale 20-MW flywheel frequency regulation plant is being constructed in
Stephentown, NY, when fully operational in 2011 it will operate in the NYISO market.

As of July 2010 Beacon has delivered and put in place the initial flywheel power electronics and
associated support equipment. The systems, consisting of power electronics, cooling and other
support equipment housed in specially equipped containers, were lowered onto permanent
foundations. After the containerized systems are wired in place, they will be interconnected with
Beacon flywheels. Support equipment for a total of 4 MW of energy storage capacity was also
delivered to the site. 80 flywheel foundations have been installed at the site, and Beacon
expects to deliver and begin installing 40 flywheels (4 MW) during 3Q10. The 4 MW are
planned to be connected and earning revenue from frequency regulation services by the end of
2010. The balance of the 20 MW plant is expected to be completed and operational by the end
of the first quarter of 2011.
New York regulators in April 2010 approved construction of a 20-MW energy storage system at
an operating coal-fired power station. The $22.3 million project, owned by AES ES Westover
LLC—an AES Corp. subsidiary—will participate in New York’s growing day-ahead market for
ancillary services and regulation. AES will build the project in two phases at Westover
Generation Plant, 175 miles northwest of New York City, starting in the second quarter of 2010.
That plant includes the 84-MW Unit 8, which entered service in 1951, and a non-operating 44-
MW Unit 7, completed in 1943. AES will connect the battery project to the power grid using Unit
7’s facilities.

Based on the pilot and demonstration projects, the project will comprise 10 containers, each 53
feet tall and capable of housing inverters and 2-MW DC battery subsystems. The units will then
be connected through standard electrical industry transformers, switchgear, and protective
relays to the high-voltage system. According to developers and the New York Public Service
Commission (PSC), the project will be able to provide or absorb some 5 MWh to and from the
system.

The site will reportedly require minor modifications to install foundations to support the energy
storage units, but no new interconnection facilities will be required to interconnect the project to
the New York State Electric & Gas Corp.’s transmission system. The PSC said in a statement
that an interconnection request has already been filed for the project with the New York
Independent System Operator (NYISO) as part of NYISO’s Small Generator Interconnection
Smart Energy 25 (Gen 4) flywheel energy storage system installed at Tehachapi in march 2010.
The system is part of a wind power/flywheel demonstration project being carried out for the
California Energy Commission. The primary goal of the project is to demonstrate that advanced
control technology with energy storage can help expand the delivery of wind energy by
effectively increasing the capacity of constrained transmission facilities in the area.

BYD intends to build a megawatt-class (~2-MW)/ 2-4 hour demonstration energy storage
system in a 40-foot mobile container. PacificCorp is still in discussions with BYD, however, and
no real project committment has been made as of yet. PacificCorp is having a hard time making
the economics work, given the Pacific Northwest market economy, etc.
Ultralife's advanced 2 MWh Li-ion battery will be integrated with a single wind turbine being
planned for installation and operation in 2011. (500 kW x 4 hrs)

This demo will result in data to confirm the technical performance and economic benefits of
Ultralife’s energy storage system, specifically targeting renewable integration, peak shifting,
peak shaving, and frequency regulation. With excess power generated by the wind turbine to be
controlled in a ―dispatchable‖ manner, SUNY Canton will be able to reduce campus peak
demands and target specific utility rate structures to lower electricity costs. SUNY Canton is
supporting the siting of both the wind turbine and energy storage projects, and will also benefit
from the projects for educational purposes.

Project encompasses demonstrating a new environmentally-friendly prototype home utilizing
BYD’s solar and battery system. BYD will provide all solar panels, batteries, LED lights,
inverters, EV charging pedestal and other necessary energy-related materials; KB Home will
provide the home site, as well as oversee the construction of the home and the installation of
the BYD system. Lancaster has committed to waive all local municipal development fees for the
project.
As part of DTE's 5-year effort to install and own 15 MW of solar (initiated to meet the State of
Michigan's 10% by 2015 RPS), the utility is working with select battery manufacturers to install a
batteries on some sites with PV. A123 is, for example, affixing a battery unit to a 500-kW PV
array on top of the company's manufacutirng facility. The deployment has been contracted and
is moving forward. Stakeholders have decided to keep the integration on the AC side by
implementing separate inverters for the battery system and the PV system. Integration
happening at 480VAC. DTE may containerize the A123 battery and move it to another site.
The McAlpine Creek project, partially involves the deployment of a 50-kW PV array at a
substation that feeds the grid or can charge up a 500-kW ZnBr system.

TBD - EPRI Li-ion Scoping initiative

Project comprises 500kW solar PV system, 2MWh (750kW) fully integrated Xtreme Power
battery/control storage system (can do KVAR or KWh power flow control), and has a vehicle
element with 10 charging stations associated. The Xtreme system optimizes the solar array
loading with the batteries and uses what appear to be DC-DC connections within the system.
This project is being conducted with DTE and has a $2M funding element from the State of
Michigan.




This 1-year project will evaluate consumer reactions when a utility provides advanced metering
and price signals for electric power without PV, with PV, and with both PV and energy storage.
The impact will be a utility-based understanding of market response for photovoltaics.




This 1-year project will evaluate the value of advanced metering infrastructure, PV, and storage
for homes with advanced metering infrastructure and PV along with the variables of no storage,
home-based storage, or community-based storage. Actual utility-collected data will be available
to assess the performance and market impacts of these options.




5-6MW to be potentially installed in 2010
Project status: uncertain
Presidio, Texas, a border town located in the southwestern portion of the state, suffers chronic
power outages and voltage fluctuations as a result of its dependence on a single aging,
transmission line. Built in 1948, the transmission line stretches 60 miles from Marfa in the high
desert to the banks of the Rio Grande along the Mexican border. Electrical storms frequently
erupt in the rugged expanse between Marfa and Presidio, disrupting power service.

To remedy the situation, Electric Transmission Texas (ETT), a joint venture between
subsidiaries of American Electric Power (AEP) and MidAmerican Energy Holdings, has invested
in a 4 MW/32 MWh NaS BESS. (AEP has itself already installed four smaller NaS systems
totaling approximately 7.2 MW.) With the purchase, ETT, which acquires, constructs, owns and
operates transmission facilities within ERCOT, became the owner of the largest NaS
deployment in the United States to date.

Part of a larger modernization project that includes plans for a new 60-mi, 69-kv transmission
line from Marfa to Presidio, the NaS BESS is intended to provide real and reactive power to
maintain reliable service to Presidio, and to supply uninterrupted emergency backup power in
the event of an outage on the radial transmission line providing power to Presidio. During such
outages, the BESS will provide interim support while Presidio switches over to temporarily
receive power from Mexican electric utility, Comisiόn Federal de Electricidad. (The switchover
process can take several hours).

10 Li-ion batteries to be installed throughout Southern service territory and integrate into
communication infrastructure; one unit in lab for testing/monitoring.
Southern California Edison has ordered two 1-MW Smart Grid Stabilization Systems (SGSS) for
pilot testing.

A123 says its first SGSS — a 2MW system housed in a 53-foot-long trailer — has been
installed at an AES facility in California, and another 16MW-worth of units have been installed at
AES Gener’s substation in Chile’s Atacama Desert, and California utility Southern California
Edison has ordered two units for pilot testing.

SCE has not yet connected its two 1-MW Smart Grid Stabilization Systems (SGSS) from A123
and so has not begun to pilot test them. These Li -ion (advanced nanophosphate) units are the
same productions units as those used by AES at its natural gas plant in Huntington Beach, CA
(2 MW / 0.5 MWh). The utility hopes to connect the units at its test facility for large transportable
devices by the end of 2010.


SCE plans to design and build an 8 MW / 32 MWh lithium ion battery system and inverter, and
connect it to a substation near the 66 kv Tehachapi Wind Resource Area. The battery will be
housed not on a trailer, as is conventional, but in a building. The demonstrations are slated to
be implemented in two years with a two-year evaluation period and a one-year wind-up
following. The project will test 13 of the 24 possible uses for energy storage urged by EPRI.

A123's batteries include nano-scale materials developed by -- and exclusively licensed from --
the Massachusetts Institute of Technology. Quanta Technology will provide measurement and
verification. California State Polytechnic University at Pomona will assist in those tasks.

Project status: the project was awarded in 2009, but A123 is still waiting on an upstream
contract from DOE/SCE.
CES deployment scheduled to commence at end-2010/beginning-2011

A123 will provide 20 CES units to demonstrate individual battery capabilities and aggregated
dispatch. This project has been awarded, but is not yet contracted. A123 is building its units to
meet specs devised by AEP (25 kW/50 kWh per unit); unit characteristics will be compliant with
AEP specs. A123 is having a hard time meeting the physical dimensioning embedded in the
spec and may deviate somewhat. The biggest challenge is space constraints.

3-year project that incorporates the fleet control engineering, manufacturing and installation of 7
500-kW/6-hour energy storage systems. Installations scheduled for 3Q10

The project will validate Premium Power’s Zinc-Flow technology, particularly in PV and micro-
grid applications, by demonstrating multiple use cases. Goal: extend peak load management,
demonstrate multiple approaches to storage integration with intermittent RE, develop / verify
control algorithms to manage fleet operation of energy storage systems that are not co-located,
and improve the performance of a micro-grid by deploying advanced energy storage with
sophisticated control systems.


EnerDel to supply Li-ions for five 1-MW power systems to be used by Portland General Electric
(PGE); Equipment will be installed at 15 sites over the next two years, after which developers
will spend 2-3 years testing system performance under wide variety of geographic and
meteorological conditions. It is one of 16 projects announced by DOE.
The project will use technology from start-up EnerVault of Sunnyvale, Calif, that has been
benchtop-tested but not manufactured. The plan is to build two batteries: a 40 kw capacity alpha-
test model and then the 250 kw version to be installed at Montpelier Nut of Modesto, CA. The
privately owned nut firm has a 180 kW PV array used to power a large irrigation pump. The
farm will be able to choose whether to run the pump off the array, off the grid or from the
battery, whichever is cheapest. Project stakeholders plan to time-shift the PV energy. The farm
is served by PG&E.

EnerVault's patent-pending technology was developed years ago at NASA but then languished
until the need for energy storage grew larger. The 250-kW test battery will consist of four 20-
foot units, stacked two by two. Each twosome will consist of an electrolyte tank on the bottom
that pumps electrolytes through an array of cells directly above it.

Ktech will do the engineering and integration, developing controls and monitoring apparatus and
integrating inverters, transducers and sensors. That will be done in Albuquerque before the unit
is moved to California. There, Ktech will collect data to measure the project's success. Startup
in ABQ occurred in January 2010, and development is expected to last one year. Relocation to




5-year effort

Will include 13 different technologies from the substation to the customer, including distribution
automation and control, smart meters and appliances, home area networks, plug-in hybrid
electric vehicles, energy and battery storage, and renewable generation sources. These
technologies are estimated to improve the reliability and efficiency of the distribution system 30-
40%.

Planning to deploy distributed energy storage (CES) systems totaling 2 MW in Columbus, OH
by mid-2011. 25 kW – 25 kVA Li-Ion battery supplied by International Battery using S&C as the
system integrator.

Demonstrate an integrated, scalable Smart Grid system that includes all of the interlocking
pieces of an end-to-end Smart Grid system - from the transmission and distribution systems to
consumer applications like smart appliances and electric vehicles. The project will focus on the
interoperability and interactions between technologies and systems working at the same time -
such as communications networks, cyber-security requirements, and interoperability standards.
Will demo end-to-end Smart Grid that will include advanced renewable generation, storage
resources, distribution system automation, in-home customer systems and digital technologies,
and innovative rate structures.

networks to improve grid reliability and safety. Will provide visibility for operators, which will
increase the system's capacity to integrate on-site energy technologies, such as solar
photovoltaic energy systems, plug-in hybrid electric vehicles or battery storage.

community battery storage, smart meters and appliances, plug-in hybrid electric vehicles and
homes equipped with 1-3 kW solar photovoltaics.
Startup Seeo will develop and deploy a 25 kWh prototype battery system based on Seeo’s
proprietary nanostructured polymer electrolytes. This new class of advanced lithium-ion
rechargeable battery is intended to demonstrate the substantial improvements offered by solid
state lithium-ion technologies for energy density, battery life, safety, and cost. These batteries
would be targeted for utility-scale operations, particularly Community Energy Storage and grid-
connected electric-vehicle projects. Seeo has an exclusive license to advanced technology from
the Lawrence Berkeley National Laboratory and was established with initial funding from Silicon
Valley VC firm Khosla Ventures.




UCSD’s microgrid operates on 26 MW of cogeneration, 1 MW of solar PV, and 60 gen-sets
totaling 32 MW, all in parallel with SDG&E's distribution network. Its 3.8-million-gallon chilled
water storage system for cooling shifts about 14% of its load off-peak. The university will add a
2.8-MW fuel cell (from FCE) paired with a 2.8-MW advanced energy storage system.

A solicitation for proposals to supply the energy storage system was released in September
2009, with responses due in 60 days. The system should have at least 12 MWh of energy
discharge capacity. Sanyo reportedly selected


ABB will lead a team developing an advanced superconducting magnetic energy storage
(SMES) device. SMES is a novel technology that stores electricity from the grid in the magnetic
field of a coiled wire with near-zero loss of energy. The proposed device will have
instantaneous response and nearly infinite cycle life. If the high-risk breakthrough technologies
in this project are successfully developed, the result will advance SMES from a high-cost
solution for delivering short bursts of energy to a technology that is cost competitive for
delivering megawatt hours of stored electricity.
Low-cost, ultra-high energy lithium-ion batteries will be developed using an innovative
manufacturing process. High energy cathodes will be integrated with new anodes and prototype
manufacturing will be demonstrated that could achieve an extremely low cost. If successful, this
project will establish U.S. leadership in the manufacturing of high energy, low cost advanced
lithium-ion batteries.

Beacon Power will lead a team in developing a next generation flywheel energy-storage
technology. In a flywheel system, electricity is stored as kinetic energy in a spinning wheel. The
proposed flywheel could store four times more energy than current flywheels at 1/8th the cost.
It employs a radically new ―flying ring‖ design that is capable of accepting and delivering energy
over 40000 times during its 20-year lifetime. The proposed technology is ideal for
simultaneously addressing both the renewable ramping challenge and other grid-storage
applications.
In this project, Boeing will develop a high-risk material technology for low-cost, high energy-
density flywheel energy-storage. In a flywheel, electricity is stored as kinetic energy in a
spinning wheel. While flywheels are currently used for short-duration energy storage, this
project will make possible a dramatic increase in the energy density of flywheels for longer-
duration applications including renewable energy ramping. To increase energy density, Boeing
will develop a new fiber material that allows the flywheel to spin at higher speeds without
breaking. The resulting high energy density material will enable subsequent scaling to utility-
size and amenable to factory production at low cost.
The project will develop a novel energy storage device – a high energy density capacitor –
based on a 3D nanocomposite structure. The approach combines the benefits of high cycling
ability, high power density, and low cost.
In this project, the CUNY Energy Institute, in partnership with Rechargeable Battery Corporation
(RBC) and the Ultralife Corporation, will develop a novel battery that radically transforms the
chemistry and low-cost materials found in disposable consumer-grade alkaline batteries into a
long-lasting, fully-rechargeable energy storage system. While CUNY has already demonstrated
some of the basic scientific principles, work in this high-risk project will achieve a rechargeable
battery system that lasts for over ten years, costs under $100/kWh, demonstrating potential for
use on the electric grid.




Fluidic Energy will develop an advanced multi-functional energy storage (AMES) battery
prototype. This is a high-risk technology which, if successful, will enable a highly scalable
energy storage system well suited for supporting intermittent renewable resources (solar, wind)
on the electric grid. The novel battery chemistry will overcome traditional electricity storage
challenges of limited re-chargeability, low power density and poor efficiency. This low-cost
battery technology will be based exclusively on domestically-available, earth abundant active
materials. A partnership with Satcon and Chevron Energy Solutions will ensure this project
translates rapidly to products supporting renewable generation on the grid.

General Atomics and the University of California San Diego will develop a novel flow battery
technology, which pumps chemicals through the battery cell when electricity is needed. The
proposed flow battery revolutionizes a century-old lead-acid battery technology to achieve low
cost, high efficiency and reliability needed for use on the electric power grid. This high-risk
technology development program will use novel materials that greatly increase power while
resisting the corrosion that limits the cycle life of conventional lead acid batteries. These
innovations will result in a battery that can be scaled for grid-scale energy storage, but which
costs less and performs far longer than today’s’ technologies.

General Compression will lead a team investigating a novel compressed air energy storage
process (GCAES™) that is highly efficient and requires no fossil fuel. In this project, a team of
industry and academic researchers will show the potential for a near-isothermal CAES unit,
which could result in an energy storage technology with high round-trip electrical efficiency and
fast response times. Unlike conventional CAES installations, no fuel will be burned in the
expansion stage of the process, dramatically reducing emissions and operating costs. Once
successfully developed, the GCAES™ can accelerate the integration of renewable electricity
generation, particularly wind, into the grid.
Lawrence Berkeley National Laboratory, DuPont, Bosch, 3M, and Proton Energy will develop a
novel flow-battery system for grid applications. Flow batteries pump reactive chemicals through
the battery cell when electricity is needed; this project’s battery will use hydrogen and bromine
as its active materials. While this type of flow battery has existed for decades, it has been
plagued by high costs, short lifetimes, and safety concerns. The storage technology would be
developed to allow solar-generated electricity to be tapped after dark or on days when the wind
does not blow. It is aimed at improving the operation of the electric grid through the temporary
storage of electrical energy with a new battery system. The project hopes to contribute to
innovation sin technology that allow for better energy efficiency while reducing greenhouse gas
emissions.
Rechargeable Li-Air batteries for electric vehicle applications will be developed using protected
Lithium metal cathodes. This approach has a clear path to scaling commercially, and the
batteries may rival the energy density of gasoline.


A new high energy air cathode will be created to enable the successful development of ultra-
high energy Lithium-Air batteries. The project will seek to dramatically improve cathode
performance through the development of a new electrode structure and improved catalysts.



The project seeks to develop an ultra-high energy Li-S battery that can power electric vehicles
for more than 300 miles between charges. The approach uses new manufacturing processes
and six physical barrier layers to address cycle life and safety.




The project will develop an inexpensive, rechargeable magnesium-ion battery for electric and
hybrid-electric vehicle applications. Computational methods and accelerated chemical synthesis
will be used to develop new materials and chemistries. If successful, this project will develop the
first commercial magnesium-ion battery and establish U.S. technology leadership in a new field.

Researchers will seek to develop an "All-Electron Battery", a completely new class of electrical
energy storage devices for electric vehicles. The new battery stores energy by moving electrons
rather than ions and uses a novel architecture that has potential for very high energy density.

This is a new battery concept that combines the best aspects of rechargeable batteries and fuel
cells. It could enable batteries for electric vehicles that are much lighter and smaller - and
cheaper - than today's batteries. This flow battery potentially could cost less than one-eighth of
today's batteries, which could lead to widespread adoption of affordable electric vehicles.


Primus Power will develop new durable, inexpensive metal electrodes for flow batteries for
energy storage on the electric grid. Electrodes are a key component of flow batteries, which
pump reactive chemicals through the battery cell when electricity is needed. Flow batteries are
potentially ideal for electric grid storage applications, but are often limited by the high cost and
poor durability of the electrodes. In this project, Primus Power will leverage processes
developed for other chemical industries to develop novel, low-cost metallic flow battery
electrodes. If successful, the result will be a 5X decrease in costs while simultaneously
doubling the power density of the energy storage system.
Proton Energy and Penn State University will develop an advanced energy storage device that
incorporates a regenerative fuel cell. Like batteries, fuel cells use chemical reactions to
produce electricity. Many fuel cells require expensive precious metals such as platinum to
operate. In this novel design, a unique component will be developed that allows the fuel cell to
operate without significant use of precious metals. This innovation will dramatically reduce cost,
and enable the economical use of this fuel cell system for electricity storage on the grid.


Princeton Power to develop complete design for a 100-kW ―Demand Response Inverter." The
design will be optimized for low-cost, high-quality manufacture, and will integrate control
capabilities including dynamic energy storage and demand response through load control.


The FSEC/UCF to develop a ―shared‖ inverter serving multiple residential or commercial PV
arrays located at a distribution transformer. Work includes battery storage, utility control,
communication, monitoring, or building energy management systems (BEMS). An ―anti-
islanding‖ strategy that allows PV to remain on line during grid disturbances will improve grid
stability. New inverter architectures will bring more stability.
EMTEC to develop, 3-phase, highly efficient, small footprint, innovative power conversion,
energy storage and energy management components for commercial-and utility-scale PV
systems. The new products will include an integrated grid controller that works in conjunction
with customer smart meters to respond to time of day pricing signals. The total system provides
improved economics for distribution and will minimize fluctuations in supply and demand of
electricity.
GE to advance residential PV generation coordination with energy storage, responsive loads,
and demand side management programs. New and enhanced three-phase inverter and
distribution system control concepts to be developed to meet anticipated new requirements for
grid connectivity.
Apollo Solar will develop advanced modular components for power conversion, energy storage,
energy management and a portal for communications for residential solar electric systems. The
inverters, charge controllers, and energy management systems will have provisions to
communicate with utility energy portals for implementation of the seamless two-way power flows
of the future.




This project seeks to develop an ultra high energy, long cycle life all solid-state lithium battery
that can manufactured using low cost techniques. Pilot-scale manufacturing of the batteries will
be demonstrated using all inorganic materials and solid state electrolytes whose properties are
similar to existing liquid electrolytes.
United Technologies Research Center (UTRC), in partnership with the University of Texas and
Sandia National Laboratory, will develop a novel flow battery, a type of battery system that
pumps reactive chemicals through the battery cell when electricity is needed. The proposed
flow battery uses a unique design to deliver 10X more power than conventional flow batteries.
The breakthrough will enable a dramatic reduction in the size and cost of the flow battery. The
advanced prototype flow battery developed in this program will provide energy storage at 1/3 the
cost of current flow battery systems, and will lay the technical foundation for commercially-
available grid-scale energy storage solution.

Researchers at the University of Southern California and NASA’s Jet Propulsion Laboratory will
team to develop a high-performance rechargeable battery for large-scale energy storage on the
electricity grid. Iron air batteries have the potential to store large amounts of energy
inexpensively since they rely on extremely low-cost materials: iron, which costs less than
$.20/pound, and oxygen which is free in ambient air. Existing iron-air batteries have suffered
from low energy efficiency and poor cycle life. So, in this high-risk technology development
project, new materials and structures will be tested with the goal of increasing battery efficiency
and cycle-life. This project will develop an iron-air proof of concept battery, the first step in the
commercialization of this promising, low-cost battery chemistry.
A large, high-energy zinc-air flow battery will be developed to enable long range plug-in hybrid
and all-electric vehicles. Zinc, suspended as a slurry, is stored in a tank and transported
through tubes to charge and discharge the battery.

and cell phone heavyweight LG, power companies KEPCO and GS Caltex, and Hyundai Heavy
Industries.
Sanyo installed two ―Solar Parking Lots,‖ incorporating solar panels and lithium-ion battery
systems for 100 electric hybrid "eneloop" bicycles. Parking lots operated by the city of Setagaya
at Keio Line Sakurajosui Station and Tokyu Den-en Toshi Line Sakurashinmachi Station.
―eneloop bike‖ is SANYO’s energy recycling electric hybrid bicycle featuring a regenerative
charging function that enables electricity generation and battery charging during riding. The 100
―eneloop bike‖ units provided at the three locations, including Odakyu Line Kyodo Station, in
addition to Sakurajosui Station and Sakurashinmachi Station will be used as ―community
bicycles‖ by a wide range of people residing in and outside Setagaya. Storage component: 6

53 MW of distributed thermal storage Intended to permanently reduce CA's peak demand by
annually shifting up to 64 GWh of peak to off-peak. Installation to begin during first half of 2010,
over two years.
Ice Energy is collaborating with SunPower on a pilot project funded by the California Public
Utilities Commission that will combine its Ice Bear energy storage technology with SunPower's
PV solar systems. The project, part of the California Solar Initiative's Research, Development,
Deployment and Demonstration Program, seeks to demonstrate the economic and operational
benefits of integrating advanced energy storage systems with existing PV systems for peak
demand reduction directly on commercial buildings. Ice Energy is one of three energy storage
companies selected to participate in the program, which will be implemented by SunPower in
conjunction with PG&E, KEMA, Sandia National Laboratories and a major national retailer. The
project is supposed to demonstrate that the combination of solar and ice storage will
significantly reduce a building's peak demand charge.

This is the first collaboration between Ice and SunPower.

The timeline for the project is that contracts will be finalized during the fall of 2010, with design,
planning and permitting completed in the first quarter of 2011 The demonstration phase is
planned for Summer 2011.

The goal of the CPUC California Solar Initiative (CSI) is to create 1,940 megawatts of new,
