McHenry Battery Storage LLC on July 8 filed with the Federal Energy Regulatory Commission a notice of self-certification that it is an exempt wholesale generator based on its ownership and operation of a 20 MW (nameplate) battery storage facility located in McHenry, Illinois.
McHenry is indirectly wholly-owned by EDF Renewable Energy (EDF-RE). McHenry owns and operates a 20 MW (nameplate) battery storage facility that is connected to the distribution system of Commonwealth Edison (ComEd).
The battery is charged from the ComEd distribution system and McHenry has entered into a Wholesale Market Participant Agreement with PJM Interconnection in order to engage in wholesale transactions within the PJM market. All the electric energy and capacity from the facility will be sold into the PJM market.
EDF RE had announced Feb. 24 that the McHenry Storage Project, parent EDF Group’s first battery storage project in North America, reached commercial operation on Dec. 20, 2015. The energy storage system, located in McHenry County, Illinois, added 40 MW of flexible capacity (20 MW nameplate) to the PJM system and will participate in both the regulation and capacity markets.
