Germany’s battery storage boom: The largest projects

The German market for stationary battery energy storage systems (BESS) is entering a new phase of rapid expansion. This article presents the largest projects that have already reached a final investment decision (FiD).

A ranking of the five largest BESS projects in Germany by capacity can be compiled from publicly confirmed projects. These projects represent not only different approaches to technology, but also different types of investors.

The five largest German BESS projects (with FiD):

1) Gigabattery Jänschwalde 1000 – 1 000 MW / 4 000 MWh

Europe’s largest battery storage facility is being built by the LEAG Group in Jänschwalde as part of the broader transformation of the former coal-mining region of Lusatia. With an installed capacity of 1 000 MW and energy storage capacity of 4 000 MWh, the project pushes the boundaries of what is considered standard in the European context. Commissioning is expected in 2027/2028.

2) Förderstedt – 300 MW / 714 MWh
