The Marengo plant will be interconnected to the local Commonwealth Edison Company (ComEd) electric grid and will provide RegD real-time frequency regulation service to PJM Interconnection (PJM). The project will respond almost instantly to the continually changing needs of the grid, allowing PJM to deliver higher-quality reliable electrical service, at a lower cost, to end users in the 13 states and the District of Columbia.
The Marengo Project was developed by GlidePath, a leading developer of advanced energy solutions, which recently sold three similar projects to British independent power producer RES and French utility EDF. The Leclanché integrated BESS provides superior performance as defined by the RegD PJM Regulation Market. The project starts construction in November 2016 and will be placed into operation in 2017
