Default 20MW Lithium-Ion Battery Storage System For New York

20MW Lithium-Ion Battery Storage System For New York

by Energy Matters

U.S. Energy Secretary Steven Chu last week announced the finalising of a USD $17.1 million loan guarantee to support the construction of a 20 megawatt (MW) energy storage system using advanced lithium-ion batteries.

Located in Johnson City, New York, the AES project will improve stability for the associated mains power grid and reduce carbon emissions by allowing for more renewable energy sources like wind and solar power.

"Bringing more efficiency and reliability to the grid will help cut costs for consumers and power a cleaner energy future", said Secretary Chu.

Grid frequency regulation is needed to balance power generation and consumption and is usually maintained by burning additional fossil fuels such as coal at power plants. Power plants become very inefficient when power output rapidly ramps in response to short-term variation in power demand. Up to 7% of the USA's electricity generating capacity is set aside to provide grid stability.

The AES project instead uses battery technology and new software that will provide the same regulation at a lower price.

The AES project will include advanced lithium-ion battery cells from A123 Systems, Inc. The company says its Smart Grid Stabilization System (SGSS) can respond in milliseconds compared to power plants which can take minutes to respond to a call to vary their power output. The system frees up plant capacity to enable a power company to focus on the primary function of baseload electricity generation.

A123 Systems says independent third party studies have found high-efficiency energy storage systems, such as the SGSS, for frequency regulation can reduce the associated emissions of carbon dioxide, sulphur dioxide and nitrous oxide by as much as 80% over traditional power plant ancillary services.

(20MW -enough for 20,000 homes)

Default 8 Megawatts already installed

The image below shows 8 megawatts Lithium battery plant already smoothing New York states power..


Lithium ion batteries aren't just for your laptop anymore. A group of truck-size battery banks are delivering quick bursts of power to the electricity grid in upstate New York.



AES Energy Storage, a subsidiary of power generation company AES, today said that the first 8 megawatts of a planned 20-megawatt battery grid storage system are now online in Johnson City, N.Y. The full project is expected to be completed later this year.



The network of batteries is designed to keep an even balance between energy supply and demand in that portion of the New York grid. The batteries will store energy and, based on a signal from grid operators, supply power for a few seconds as needed.

Default Vanadium based large storage battery for mass storage?

I wonder if the VRB (Vandium Redox Batteries) will be the answer to mass electricity storage derived from green energy?

I have started to explore this topic at http://www.australian-shares.com/vanadium-australia under the heading "Vanadium has recently described as being central to the "Holy Grail of Renewable Energy" -Grid Scale Power Storage"


This could be a useful topic to get our heads around........

Hi.. I gather some information regarding geothermal I am here to share with you. Geothermal is another great , cheap, and renewable energy source. It is capable of high capacity factors. It provides electricity at low cost. These projects provide growth and jobs in rural areas. The cost of geothermal plant is low it depends on how we are using this free renewable energy sources.


Sparty: Hi Tom I agree with you.... have a look at HotRockEnergy.com another of our energy related websites....
