A123 Systems will supply advanced lithium-ion battery cells for a 20 MW energy storage system in NY State.
The Dept of Energy (DOE) announced it finalized a $17.1 million loan guarantee for the AES Westover energy storage facility, which will contribute to a more stable, efficient electrical grid for the state’s high-voltage transmission network.
"The AES project helps reduce carbon emissions and strengthens our energy infrastructure by allowing for more renewable energy sources like solar and wind to contribute to the electrical grid," said Secretary Chu.
Traditionally, grid frequency regulation, which is needed to balance power generation and consumption on the grid, is maintained by burning additional fossil fuels at power plants. The AES project eliminates the need to burn fossil fuels and instead uses battery technology and new software that will provide the same regulation at a lower price, while reducing carbon emissions 70%.

This would be a major turning point for future revenue growth. Efficient load balancing in electrical grid has always been a challenge. Use of high capacity storage facility as provided by A123 Systems would be a highly cost effective way of tackling the problem.
The story didn’t say how man MWH would be stored. I assume the system can supply 20MW but for what length of time?
