Eco Stor Plans 103 MW/238 MWh Battery Storage Project in Germany

German-Norwegian power storage systems provider Eco Stor GmbH is planning to build a 103.5 MW/238 MWh battery energy storage system (BESS) in northern Germany.

The new battery will be located in the municipality of Schuby, in the federal state of Schleswig-Holstein, near the Schuby West substation and 5 km from the 103 MW/238 MWh Bollingstedt storage facility already under construction by Eco Stor.

The site was selected in cooperation with EPW GmbH as a partner for regional project development. Construction work is planned to begin in November 2024.

The battery in Schuby is Eco Stor's fourth major project in Germany alongside Bollingstedt, the 300 MW/660 MWh-Wengerohr and the 300 MW/660 MWh Foerderstedt projects.

The storage facility is designed to charge excess wind and solar power twice daily when solar and wind power plants operate at full capacity and electricity prices are low. The power from the battery is fed back into the public grid during the morning and evening peaks in power demand when there is little renewable energy in the grid and prices are high. This means that around half a million multi-person households can be supplied with renewable power for two hours each in the morning and evening. Thus the share of renewables in the electricity mix can be increased while at the same time ensuring security of supply.
