Major BESS Milestones in Germany: GIGA Storage and Vattenfall Advance Gigawatt-Scale Projects

Germany remains the undisputed leader in Europe's battery storage market, having added 6.6 GWh of capacity in 2025 alone. Driven by rapid renewable expansion and price volatility, the country is witnessing a surge in gigawatt-scale battery energy storage system (BESS) developments.

GIGA Storage Secures Grid Connection for Albatross

In a major milestone, GIGA Storage and German transmission system operator Amprion have signed a grid connection agreement for the 350 MW/1.4 GWh Albatross BESS project in Lower Saxony. This marks Amprion's first grid connection for a large-scale battery project. The system will connect to the 380 kV transmission grid via the Merzen substation, offering four hours of storage at full power. Having reached Ready to Build status in early October 2026, commissioning is planned for 2028.

Vattenfall Awards 1 GWh Contract to Fluence

Meanwhile, Vattenfall has awarded Fluence Energy a contract to deliver a massive 254 MW / 1,000+ MWh (1 GWh) BESS in Brunsbüttel. The four-hour facility will be constructed on the site of the decommissioning Brunsbüttel nuclear power plant. Scheduled for commissioning by the end of 2028, it will connect to the 50Hertz 380 kV network and nearly double Vattenfall's operational battery capacity.

Additional Utility-Scale Developments

The momentum continues with Enlight and ENERTRAG starting construction on an 840 MWh BESS in Bertikow, and N-ERGIE alongside MaxSolar breaking ground on a 20 MW/100 MWh grid-operated facility in Bavaria. These projects underscore Germany's robust pipeline and its pivotal role in the EU's energy transition.

As the German grid integrates more wind and solar power, these utility-scale assets will be essential for providing flexibility, balancing supply and demand, and ensuring the overall stability of the European interconnected power system.
