Twin Groves Energy Storage I & II

Installed capacity of 100 MW / 400 MWh

Project overview

Twin Groves Energy Storage I & II represents an expansion of EDPR NA’s energy infrastructure in McLean County, Illinois. The energy storage sites will be located in the Arrowsmith and Ellsworth Townships, alongside EDP NA’s existing Twin Groves Wind I & II.

Once online, these projects will share some of the existing electrical infrastructure from Twin Groves Wind I & II. The low-impact batteries will provide additional storage capacity for the utility and system operators by storing electricity from any energy source and delivering it to surrounding communities when needed.
