Additional information

The storage plant will provide frequency regulation services to Germany’s Primary Control Reserve (PCR) market to rapidly stabilise the grid, and will later be integrated with ENERTRAG wind farms. The first 2 MW section of the Cremzow plant is expected to be operational in April 2018, while the launch of the entire plant is planned for the end of this year. The facility will be owned by a special purpose vehicle (SPV) in which EGP Germany has a 90% majority stake and ENERTRAG the remaining 10% stake.
