German-Norwegian power storage systems provider Eco Stor GmbH is set to embark on the development of a substantial 103.5 MW/238 MWh battery energy storage system (BESS) in northern Germany.
Located in the municipality of Schuby, within the federal state of Schleswig-Holstein, the new battery facility will be situated near the Schuby West substation and approximately 5 km away from the 103 MW/238 MWh Bollingstedt storage facility, also being constructed by Eco Stor.
The selection of the site was a collaborative effort with EPW GmbH, a partner specializing in regional project development. Construction is slated to commence in November 2024.
This endeavor marks Eco Stor's fourth major project in Germany, joining the ranks of Bollingstedt, the 300 MW/660 MWh-Wengerohr, and the 300 MW/660 MWh Foerderstedt projects.
The storage facility's primary function is to capitalize on excess wind and solar power by charging twice daily during periods of peak renewable energy generation and low electricity prices. Subsequently, the stored energy is injected back into the public grid during morning and evening peaks in power demand when renewable energy sources are less abundant and electricity prices are higher.
In practical terms, this approach facilitates the provision of renewable power to approximately half a million multi-person households for two hours each during morning and evening peaks.
