Because grid frequency regulation – which is needed to balance power generation and consumption on the grid – is traditionally maintained by burning fossil fuels, grid stabilization often comes with the associated financial and environmental costs.
By developing a 20 megawatt (MW) energy storage system using advanced lithium-ion batteries, the AES project will eliminate the need to burn fossil fuels and provide the same regulation at a lower price.
Having this advanced frequency regulation capability could potentially help reduce carbon emissions from today’s methods by 70 percent and will allow renewable electricity generation to play a larger role in New York’s transmission network – a huge step toward meeting the President’s goal of doubling renewable energy generating capacity by 2012.
