Renewable Energy Systems Americas Inc. (RES Americas) is building two 19.8 MW, 7.8 MWh grid-scale energy storage projects outside of Chicago.
The Elwood Energy Storage Center will be located in West Chicago, and the Jake Energy Storage Center will be located in Joliet, Ill.
Both projects will provide real-time frequency regulation service to the PJM ancillary services market and are interconnected to the local Commonwealth Edison (ComEd) electric grid.
The lithium iron phosphate battery storage modules for the projects will be supplied by BYD America. The projects consist of 22 identical energy storage modular units – 11 per site – each of which will be a self-contained energy storage system containing thousands of individual battery cells, power conditioning equipment, and safety and monitoring systems. The energy storage control and dispatch systems will be developed and provided by RES Americas.
RES Americas acquired the projects during the development phase from Glidepath Power in September. Construction is expected to begin on both projects this winter, with completion by August 2015. The projects are expected to operate for at least 10 years.
‘These projects will increase the reliability and quality of ComEd's grid in these communities, which, in turn, may help attract new business that demands a high-quality and reliable electricity supply,’ says Victor Babbitt, vice president of energy storage for RES Americas.
