AS A CONCEPT, ENERGY STORAGE HAS IMMEDIATE APPEAL. IT
transfers energy through time, from generation to consumption, just as energy
transmission transfers energy from one place to another. Indeed, in the early
days of electricity, the Leyden jar and Volta’s columnar apparatus were very
much cutting-edge technology. However, after the invention of the dynamo, ac
generation, and the spectacular spread of continental electric grids, the storage
of electricity became relatively unimportant—with one exception. The lead-acid
battery became an essential ingredient of the automobile. Due to large produc-
tion volume, this battery has become relatively inexpensive and fairly reliable.
More recently, energy storage has also become a critical component of electron-
ic equipment such as portable computers and mobile phones. In this market,
where cost is less important, the need for greater energy density, zero mainte-
nance, and long cycle life has allowed advanced batteries such as lithium-ion
(Li-ion) and nickel-metal-hydride batteries to find wide application.
By contrast, energy storage (other than pumped hydro) has found very little
application in utility or large-scale industrial applications. A large 20-MW/15-min
storage facility in Puerto Rico kept the entire island grid stable for several years.
Because the battery was designed primarily as an energy source for spinningreserve but was used as a rapidly fluctuating power source performing frequency
regulation, it reached end-of-life prematurely and did not meet predicted life
expectations. However, recognizing its vital importance to the island, the facility
has recently been repowered with 20 MW of tubular plate lead-acid batteries. An

even bigger 27-MW/15-min facility was commissioned in
Fairbanks, Alaska, in 2003. It utilizes nickel-cadmium batteries
and does an excellent job providing voltage support for the
long transmission line from Anchorage. Even when not dis-
charging, it can supply about 10 Mvar. Similarly successful is a
250-kW/8-h vanadium redox facility that was put into service
on a long distribution line in Utah. In Wisconsin, a system of six 1-MW/1-s superconducting magnetic energy storage
(SMES) devices was effectively used to inject power into a col-
lapse-prone transmission loop. A number of demonstrations in
the 100-kW to 1-MW range have been field-tested with the
U.S. Department of Energy’s support and in cooperation with
major utilities. Technologies include lead acid, zinc bromine
(ZnBr), Li ion, and sodium sulfur (NaS). In addition, a consid-
erable number of megawatt-sized lead-acid uninterrupted
power supply (UPS) systems are in operation throughout the
United States for financial institutions, server farms, airports,
and the like. Japan, on the other hand, boasts over 70-MW
installed capacity for NaS technology alone—the largest facil-
ities at 8 MW/8 h.
Meanwhile, analytical studies have shown the applicabili-
ty of energy storage for voltage support and frequency sta-
bility, for peak shaving, renewables firming, transmission
upgrade deferral, and a host of other uses. Many of these
applications are already cost-effective with current storage
technologies. This cost-effectiveness is enhanced if several
compatible applications, such as arbitrage and transmission
deferral, are combined.
Estimates of the potential market for energy storage in the
United States are quite large. A recent study on the California
market extrapolates to some 80 billion watts, or US$60 bil-
lion, for the maximum market potential (assuming a not unre-
alistic cost of US$600/kW for the storage system). The
cumulative potential market for energy storage systems in
California is shown in Figure 1 as a function of system cost.
While this study does not take into account market penetra-
tion or competing technologies, it does demonstrate the sheersize of the potential market.
Several drivers underscore the need for widespread appli-
cation of energy storage. Recent major outages have shown
the need for grid reliability, particularly in view of the grow-
ing digitization of industry and commerce. Terrorism has led
to security issues which are often similar to reliability con-
cerns. Mandates for renewable energy raise grid stability and
dispatchability issues. Grid unreliability is a problem of very
real economic impact. A recent study estimates outages cost
the United States some US$79 billion per year. Interestingly,

deterrent for further installations. Clearly, a new strategy is
needed if energy storage is to gain acceptance as a solution to
the many applications for which it is eminently suited.
In the United States there tends to be a distinct funding
discontinuity between the long-range and more basic technol-
ogy research of federal agencies and the short-term commer-
cial interest of industries and utilities. In countries such as
Sweden or Japan, national and local governments maintain
much closer relationships with industry, accelerating the path
from research to commercialization. In the United States, the
natural partner to bridge this gap would appear to be the
states themselves. The DOE’s Energy Storage Program has
formed collaborations with the California Energy Commis-
sion (CEC) and the New York State Energy Research and
Development Authority (NYSERDA). California and New
York are among the states most active in finding new energy
solutions. Both states contain large urban centers with trans-
mission constraints. Both states also have mandates for
renewable energy.
The goal of these partnerships with the states is to demon-
strate electric energy storage as a technically viable, cost-
effective, and broadly applicable option for increasing the
reliability of the electricity system and for electric energy
management. In their capabilities and perspectives regarding
energy storage, the federal and state governments each have
distinct strengths, which are summarized in Table 1.
The DOE is collaborating with California (through the
CEC) and with New York (through NYSERDA) through
two separate initiatives. The CEC collaboration started in
2001 with an initial agreement to work together to formu-
late a series of demonstration projects. It was decided that
these should be demonstration projects for near-commercial

products and should have an economic basis. Following the
announcement of the CEC program, the DOE reached an
agreement with NYSERDA for a similar program, which
utilizes each other’s strengths but with a somewhat different
emphasis. Both programs resulted in open solicitations,
have reached the stage of contract placement, and are pro-
gressing nicely.
DOE’s programmatic goal for the two state initiatives is
the collection, analysis, and dissemination of data relevant to
near-commercial electric energy storage applications, sys-
tems, and products carried out in close association with San-
dia National Laboratories. This analysis and new information
will help the storage community by increasing the collective
knowledge of currently available energy storage systems and
their operations, uses, benefits, and potential obstacles. The
new examples of carefully analyzed and evaluated storage
systems can be expected to help accelerate the growth and
maturation of the electric energy storage industry.
The CEC/DOE Electrical EnergyStorage CollaborationCalifornia’s economy is heavily dependent on having a reli-
able transmission and distribution system. The energy crisis
of 2001 underscored the need for avoiding extreme price
volatility of electricity prices. California’s effort to foster
energy efficiency requires reducing peak electricity demand
and increased use of base load generation resources. The
state’s well-diversified but underutilized renewable energy
portfolio, wind energy systems in particular, requires full uti-
lization. Electrical energy storage (EES) in its myriad mani-
festations, from a few milliseconds to several hours, holds the
promise of solving several of these issues. Concurrent devel-
opments in auxiliary technologies—such as controls, com-
munications, and power electronics—have made it possible
to successfully integrate emerging electric energy storage
technologies for a range of applications that can solve someof the problems facing California.
Since 1990 California has periodically funded develop-
ment of electrical energy storage technologies. Yet, it was only
in 2001 that the CEC’s Public Interest Energy Research
(PIER) initiated a comprehensive program for using EES
technologies to solve problems in the area of grid reliability,
renewable energy integration, and demand management. The
initiative involved leveraging DOE’s investment in research
and development of electric energy storage components and
systems and focusing more on the integration of these tech-
nologies in California’s electrical system. This approach was
based on the premise that there are certain inherent strengths
in federal and state government entities that are highly com-
plementary (Table 1). Not duplicating each other’s efforts is
bringing about expediency and efficiency in the deployment
of storage technologies.
Consequently CEC and DOE signed a memorandum of
understanding (MOU) regarding energy storage to promote
program coordination, information sharing, sharing of other
relevant expertise, and the program management of project
implementation elements as defined in the MOU.
In July 2003, the CEC issued a request for proposals
(RFP) on energy storage demonstration projects. Projects had
to involve emerging, innovative storage technology, develop a
detailed benefit analysis up front, provide for extensive data
collection, and be located in California. The DOE’s Energy
Storage Program, through Sandia National Laboratories, had
created a methodology for estimating the economic value of
proposed demonstrations. This methodology was published
with the RFP as Attachment 14.
Monitoring the technical and economic performance of the
systems, once they commence operation, will be supervised
by DOE through Sandia. This third-party validation is of criti-
cal importance in California if the potential users are to devel-
op confidence in the EES performance and economics.
To date the initiative has resulted in securing three projects
spanning applications in the transmission, distribution, and
customer use of storage technologies resulting in a US$9.6
million three-year program. This is a heavily leveraged
three-year program with the CEC providing US$3.8 million
in funding, the DOE providing US$1.2 million, and the
projects themselves contributing (in cost share) more than
US$4.6 million. The primary purpose of the demonstrations
is to showcase near-commercial electric energy storage
devices that can demonstrate a positive cost benefit for the
electric energy consumers of California. A turnkey ap-proach was specified that will result in the commissioning
of fully operational systems based on emerging technology
electric energy storage devices. There is a distinct possibili-
ty that through collaboration with the DOE, one or two
additional projects might be added to California’s EES port-
folio in the near future.
✔ ZBB Energy Corporation, Menomonee Falls,
Wisconsin. This project is designed to mitigate substa-
tion congestion by placing a 2-MW, 2-MWh zinc-
bromine flow battery at a Pacific Gas and Electric

(PG&E) substation. The project is currently in progress
with the assembly of the battery system at the ZBB
factory in Wisconsin. The battery consists of four 500-
kW, 500-kWh modules operating under a master con-
trol to dispatch energy from the battery to mitigate
overload conditions at a selected substation. Following
testing at the PG&E distributed utility integration test
facility, the battery will be installed at a substation that
experiences periodic overload conditions. The battery
will be operating in a standby mode to supply extra
power as required. Savings created by deferring the
capital investment in upgrading the marginal substation
make this an economically viable project. Another
expected benefit will be the ability to easily move the
storage system from a summer peaking substation to a
winter peaking substation, thereby avoiding multiple
upgrade costs using a single storage system. ZBB’szinc-bromine flow battery was developed over a num-
ber of years with DOE funding. A Detroit Edison
demonstration of the battery is shown in Figure 2.
✔ Beacon Power Corporation, Wilmington,
Massachusetts. This project, a 75-kW/15-min flywheel
energy storage system, is designed to provide frequen-
cy regulation on heavily congested power distribution
facilities. Existing BHE6 Beacon flywheels modified
with a larger motor will be used. Seven flywheels will
produce 50–100 KW for 15 min. Charge and discharge
will be initiated by an ISO generated signal. The sys-
tem will store energy when generation exceeds loads
and will discharge energy when load exceeds genera-
tion, thereby stabilizing the frequency. The current,
inefficient practice is to constantly adjust generator
output. The flywheels will be assembled in a trans-
portable container and installed at PG&E’s distributed
utility integration test site in San Ramon, California.
Control systems will be developed to validate the abili-
ty of the system to follow existing AGC signals as well
as faster changing signals. A low cost, Internet-based,
dispatch system will be tested to interface with the ISO
Energy Management System.
✔ Palmdale Water District, Palmdale, California. This
project aims to minimize the impact of variable winds
on a 950-kW wind turbine attached to the treatment
plant microgrid by using a 450-kW supercapacitordevice. During power outages, energy storage will also
provide ride-through for critical loads until emergency
generation can be brought online. While providing reli-
able energy for the microgrid, the project will in turn
help reduce transmission and distribution congestion in
the area. A view of the water district site is shown in
Figure 3.

(NYSERDA) programs are actively pursuing the demonstra-
tion of innovative technologies for enhancing the reliability
of the state’s electric grid. Although generating supplies are
adequate statewide, there are regional deficiencies as a result
of existing transmission-line limitations. This is particularly
acute in downstate metropolitan New York and Long Island.
Regional programs to add distributed generation capacity,
and to aggregate existing standby generation capacity in grid
emergencies, are in place. Concurrently, projects for develop-
ing renewable generating capacity with minimal environmen-
tal impact are also under evaluation.In the area of electric energy storage, NYSERDA’s inter-
est is directed toward new technologies that may provide eco-
nomic, environmentally sound alternatives for supporting the
grid. Electric storage applications in the state could include
applications for peak load shifting, resulting in reduced con-
sumer costs, transmission and distribution equipment upgrade
deferral, frequency regulation, grid voltage support, and
emergency power. It is anticipated that providers of energy
storage services eventually will be able to participate in the
state’s various competitive electric markets.
Electric storage technologies are expected to be effective
for coupling renewable energy generation to the grid. The
implementation of the state’s renewable portfolio standard
policy will result in producing sizable new generating capaci-
ty with fluctuating output. Energy storage can control the
peaks and valleys of renewable generation and assure grid
stability and reliability.In March 2004 NYSERDA entered into an MOU with the
DOE’s Energy Storage Program to encourage, support, and
facilitate planning, implementation, and information transfer
of electric energy storage-related demonstration activities.
Specifically, the purpose of this MOU was to launch a joint
solicitation on energy storage technology.
Subsequently, NYSERDA issued program opportunity
notice (PON) 846, as a joint NYSERDA/DOE energy storage
initiative to invite proposals to: 1) demonstrate emerging
electric energy storage technologies at New York State sites;
2) develop innovative electric storage technologies that can
lead to new commercial products manufactured or packaged
in New York State; and 3) perform market analysis/feasibility
studies for energy storage applications in New York.
NYSERDA’s role in the initiative is to provide contract
and administrative management and control, conduct the
evaluation and selection of proposals, and provide contract
and administrative management of the selected projects.
NYSERDA will coordinate technology transfer activities of
the electric energy storage projects with assistance from the
contractors, DOE, and other organizations interested in ener-
gy research.
DOE’s role in the initiative is to assist in the evaluation
and selection of proposals, provide technical management of
the selected projects, oversee the data collection and analysis
for selected demonstration projects, and oversee the perform-
ance of selected projects. These tasks will again be handled
through Sandia National Laboratories.
Eight submitted proposals were selected for NYSERDA
funding and contracts are in preparation. In round numbers,
DOE will contribute US$900,000, NYSERDA will provide
US$2.6 million in funding, and US$3.6 million will be the
cost share of the awardees. This is a very highly leveraged
program for all the participants.
Two major energy storage demonstration projects were
selected for the joint initiative. Unlike the CEC projects,
these will be technical demonstrations only.
✔ New York Power Authority (NYPA), White Plains,New York. This project will shift a compressor peak
load from on-peak to off-peak and provide emergency
backup power at a major Long Island bus depot facili-
ty. The proposed EES is a NaS battery system. Peak
load reduction is becoming an urgent need in urban
areas suffering from congested transmission lines, par-
ticularly during the summer peak. The primary appli-
cation will be to supply 1 MW of power to a natural
gas compressor for six to eight hours per day, seven
days a week. The compressor fuels new natural gas

buses that are replacing diesel-fueled buses. The com-
pressor system is shown in Figure 4. The turnkey sys-
tem will be provided by ABB, Inc. to include the
power conversion system and overall system integra-
tion plus the NaS battery by NGK Insulators, Ltd. of
Japan. This project builds on the success of a smaller
100-kW NaS project, cosponsored by DOE, at anAmerican Electric Power research site in Columbus,
Ohio. It will be the first full-scale installation of NaS
technology in the United States.
✔ Beacon Power Corporation, Wilmington, Massachu-
setts. This project’s aim is to provide grid frequency
regulation by utilizing a high-energy flywheel storage
system. Frequency regulation is necessary to balance
the constantly varying differences between electricity
generation and load. This demon-
stration will follow the CEC proj-
ect adapting successes
demonstrated in California. The
demonstration will consist of a
50- to 100-kW system of seven
Beacon flywheels adapted to
operate on Niagara Mohawk’s
distribution grid and physically
located on the customer side of
the meter at an existing industrial
site in Amsterdam, New York. A
15-kW flywheel is shown in Fig-
ure 5. The primary difference
between the two projects is that
the NYSERDA facility will be on
a customer site, taking care of
random problems at the site,
while the CEC device will be test-
ed in a laboratory environment
where controlled disturbances can
be injected and the performance
analyzed.
✔ Gaia Power Technologies, New
York, New York. This project will
demonstrate a demand-reduction
and load-leveling device for edge-
of-grid scenarios with economic
benefits to the local utility and the
rural electricity user. This studywill be comprised of two parts,
testing the application of electricity storage technology
in distinct scenarios using an 11-kW, 20-kWh Gaia
PowerTower installed at a residence in the Delaware
County Electric Cooperative (DCEC) territory. The
PowerTower will provide demand reduction as the load
at the user exceeds a preset threshold. The battery will
also supplement a 5-kW fuel cell as the primary elec-
tricity source, boosting power to the user as needed.
The project should be of particular benefit to rural
cooperative utilities with isolated customers on long
distribution lines.
These three energy storage demonstrations are scheduled
to be commissioned in New York during 2005. They will run
for a minimum 18-month period and will be fully monitored
and carefully analyzed during that time.
There is one product development project which wasselected for funding:
✔ AFS Trinity Power, Livermore, California. This proj-
ect is to qualify a new flywheel rotor supplier located
in New York State. AFS Trinity has selected Power
and Composite Technologies, Inc. (PCT) of Amster-
dam, New York, as a new rotor supplier for this proj-
ect. The flywheel power system currently under
development can operate at a maximum speed of
37,000 rpm and produce 250
kW of power. The system can
store and discharge 1 kWh of
energy. PCT will develop the
capability to supply and fabri-
cate all-carbon rotors with
press-fit rims. This new capabil-
ity will permit PCT to become a
supplier of composite rims to all
flywheel manufacturers. The
project builds on work previous-
ly funded by the DOE’s Energy
Storage Program.
Three analysis projects were also
selected. A market analysis by Distrib-
uted Utility Associates has the objective
to characterize a) the potential benefits
from use of grid interactive, modular
electric energy storage and b) the market
potential for storage for a range of plau-
sible applications in the state of New
York. This analysis will provide a frame-
work to evaluate demonstrations or tech-
nology developments that address a
viable value proposition for application
with significant amounts of storage. The
evaluation will also include a characteri-
zation of important implications for tar-
iffs in New York. This study builds on a
previous DOE-funded study, which did asimilar evaluation for California.
An analysis project, by EPRI-PEAC will develop a com-
plete regulatory and market analysis methodology and apply
it to conditions in the area controlled by the New York Inde-
pendent Systems Operator (NYISO); this will serve as the
backbone for a detailed technical siting analysis for energy
storage projects. Prospective locations in New York State
will be identified based on the regulatory and market analy-
sis, and appropriate energy storage technologies will be
selected.

Ridge Energy Storage & Grid Services will perform a
market analysis study to assess the feasibility of small com-
pressed air energy storage (CAES) for transmission conges-
tion management and wind firming/shaping applications in
New York. This study is the first phase of a larger effort to
create a practical, economic, bulk energy storage facility in
the 10–15 MW range. It builds on a previous study funded by
DOE to evaluate the potential of CAES to increase the capac-
ity factor for bringing wind energy from West Texas over bur-
dened transmission lines.
Implementation of Federal/StateCollaborationsBoth the CEC/DOE and NYSERDA/DOE collaborations
follow the same general pattern. The DOE’s Energy Storage
Program, through Sandia National Laboratories, has devel-
oped wide technical expertise in storage technologies,
power conversion systems, application studies, data collec-
tion and analysis, and system integration, while the states
have a clear idea of the issues facing their electrical systems
(Table 1). In both collaborations, DOE/Sandia participated
in RFP preparation and the formulation of procurement doc-
uments by matching the state’s identified potential needs
with applications that could be satisfied by the current state
of the art of storage industry.
Unique to the CEC program was the desire to demonstrate
the economic benefit/cost ratio for the proposed systems.
Since no generally accepted method of calculating energy
storage benefits existed, Sandia contracted with Distributed
Utility Associates to generate a uniform methodology for cal-
culating the benefit of energy storage systems. This method-
ology was published as an attachment to the CEC’s request
for proposals and each bidder was required to estimate the
benefits of their system. It was hoped, but not required, that
the benefit/cost ratio would be greater than one.
Each state was responsible for publishing the procure-ment package, managing the procurement process, and con-
tracting with the energy storage system manufacturers.
Sandia worked with each state to determine the instrumenta-
tion and data acquisition procedures that would demonstrate
successful completion of each state’s requirements. Conse-
quently, for respective collaborations, Sandia has contracted
with PEAC and EnerNex as data acquisition and analysis
managers through competitive procurements. Technical
guidance is provided to both the successful manufacturers
and to the data acquisition contractors.
Each energy storage system proposed for the CEC/DOE
and demonstrations projects of the NYSERDA/DOE initia-
tive includes a customized data acquisition system for the
purpose of providing system operational data. These data will
be used in the evaluation and generation of reports on the
overall performance of the energy storage system. Data
acquisition rates must be adequate to monitor the type of
operation the system is designed to perform. For example,
power quality operations require high-speed data acquisition
on the order of microseconds in order to adequately capture
power-quality or system-stability events. In contrast, energy
management operations, such as peak shaving or arbitrage
applications, require sampling on the order of milliseconds to
seconds with 15 min averages
The data management contractors will be responsible for
conducting an overall analysis of the system’s technical per-
formance for each of the energy-storage demonstrations. For
the CEC projects, the economic performance will also be
evaluated and compared to the original expectations.
Although the actual electricity storage device itself is of high
interest to the DOE’s Energy Storage Program, even more
important is the functioning of a fully integrated system
designed to meet the requirements of a particular application.
Consequently, the focus of the analysis is on the turnkey per-
formance of each system supplied by the various contractors
selected under the two programs.
The data management contractors are also responsible for
developing and maintaining a Web site for routine review by
the general public and other groups interested in the perform-
ance of the systems.
Conclusions and Outlook The collaboration between the states of California and New
York and the DOE’s Energy Storage Research Program is
proving to be an outstanding success. The administrative hur-
dles were smoothly resolved and technical management of the projects is well underway. The states’ contribution
amounts to some US$6.4 million, while the DOE share is
US$2.1 million. Most gratifyingly, the cost share from the
private sector is a sizable US$8.2 million.
The selected projects show a good portfolio of advanced
energy storage media: a ZnBr flow battery, the NaS battery,
supercapacitors, and flywheels. The applications are equally
varied: mitigation of substation congestion, grid frequency con-
trol, load management, and stabilization of a microgrid. The
demonstration projects are intended to last for a three-year peri-

od. After that, some may be dismantled, others may continue to
be monitored, and some may become permanent installations.
One direction for future projects immediately suggests
itself. Ambitious mandates for renewable energy are either
enacted or being considered by California and New York.
In California, the law requires 20% renewables by 2017.
More stringent goals are being sought by the CEC. In NewYork, a renewable share of 25% is under negotiation. Such
a large amount of intermittent energy is difficult to accom-
modate on a grid. Energy storage, however, can make
renewables a useful, dispatchable part of the system. Stor-
age for renewables offers itself as a natural topic for future
collaborative initiatives.
Another direction for potential collaborations is of
course the rest of the United States. Although the East Coast
and the West Coast have been involved, DOE would wel-
come similar initiatives throughout the country. Such col-
laborations need not be with individual states but could well
include several states; New England and the midwestern
states suggest themselves.
State/federal collaborations can become an important tool
for bridging the gap between research and the market place.
Energy storage intends to make full use of this opportunity. It
is to be hoped that the projects undertaken as part of these
collaborations will become the vanguard of many more stor-
age facilities in future.
