McHenry Storage


The McHenry Storage Project, EDF Group’s first battery storage project in North America, reached commercial operation on December 20, 2015. The 20 MW energy storage system is located in McHenry County, Illinois.

The success of the project was due to EDF Renewables’ broad experience in renewables and the expertise of EDF Store and Forecast, who provided the command and control to optimize the triumvirate between cost, longevity and performance of the battery system. EDF Store and Forecast will continue to monitor the facility.
