IPP Zelestra has agreed a long-term toll for a 99MW/297MWh BESS project in Germany with the trading arm of UK-based power group Centrica.
The tolling agreement covers the 99MW/297MWh standalone Hilgermissen battery energy storage system (BESS) and enables Zelestra to proceed to construction. It is located in Lower Saxony, northwest Germany.
Zelestra will build, own and operate the system while Centrica Energy will trade and optimise the contracted capacity, in return for paying Zelestra a fixed fee. It effectively sees Centrica Energy rent the capacity from Zelestra.
