Imperial Irrigation District (IID) is installing a large-scale battery system that will help integrate around 50 MW of solar generation capacity to the local grid. The project will involve the installation of a 30 MW / 20 MWh battery-based energy storage system with 92 kV interconnection. The IID battery will help the grid accommodate power from two large-scale solar projects, Midway III and SunPeak 2.

The facility, sited near the El Centro Power Plant Unit 3 Repower Project, will aid grid flexibility and increase reliability on the IID network by providing solar ramping, frequency regulation, power balancing and black start capability for an adjacent gas turbine.
