In April 2018 we commissioned a behind-the-meter energy storage system (ESS) that run within an 8MW solar plant for French energy supplier Engie in Salles-sous-Bois in southeastern France.

Connected to the national grid, the Autarsys ESS is at the center of a research and development project for Engie Green.

The project will test a variety of renewable system capabilities like PV ramp rates, smoothing, and peak shaving, as well as on-gird features like frequency and voltage regulation and reactive power compensation.
