A Milestone for German Grid-Scale Storage

ECO STOR has officially completed the construction of Germany's largest built and financed battery energy storage facility in Förderstedt, Saxony-Anhalt. The massive facility features a capacity of 300 MW and over 700 MWh of storage. The infrastructure comprises 192 lithium-ion battery containers, 96 inverter and transformer containers, and a dedicated 110 kV substation. The project is scheduled to be connected to the grid in 2027, marking a significant milestone for the country's energy transition and its ability to manage high shares of renewable generation.

Comprehensive Insurance Backing

Highlighting the growing financial maturity of the sector, HDI Global acted as the sole underwriter for the ECO STOR project. The comprehensive insurance package covers erection and business interruption (BI) during the construction phase, seamlessly transitioning to electronic equipment insurance with BI cover during the operational phase. This risk mitigation is crucial for large-scale infrastructure deployments and provides confidence to project financiers.

With 300 MW and over 700 MWh of capacity, the Förderstedt facility sets a new benchmark for grid-scale battery storage in Germany.

Expanding Pipelines and Market Demand

ECO STOR is not stopping at this single project. The company currently has 3 GW of additional battery storage projects in its development pipeline, aiming to deliver a total output of 10 GW across 30 sites by 2030. This ambition reflects the broader market dynamics in Germany. Following the Federal Network Agency's confirmation that grid fee exemptions for new BESS projects will continue until August 2029, over 15GWh of large-scale BESS capacity has advanced across the country. Investor demand remains robust, as evidenced by developer Hansa Battery recently selling a 99 MW ready-to-build standalone BESS project in Lower Saxony to an undisclosed renewable independent power producer, highlighting the strong appetite for German grid-scale storage assets.
