Technical FAQs 4

How many battery storage systems are there in Germany?

The latest figures for this year are 362,537 systems with a power output of around 2.6 GW and a cumulative storage capacity of 4.59 GWh. From ESS News The market data register of Germany’s Federal Network Agency (Bundesnetzagentur) lists 2,093,855 battery storage systems with a gross output of 15.24 GW and a usable storage capacity of 23.16 GWh.

How many battery storage systems were installed in Germany in 2024?

Almost 600,000 new stationary battery storage systems were installed across Germany in 2024, increasing the country’s storage capacity by 50 percent year-on-year, according to preliminary data from the German Solar Industry Association (BSW Solar).

What if a battery storage project was approved in Germany?

If only half of these projects were approved, they would store enough energy to power 30 million German households for one day. Battery storage is needed to supplement the country’s rapid rollout of renewable energy installations, which reached a new record share in electricity production of 55 percent in 2024.

How do large battery storage systems support the energy transition in Germany?

Large battery storage systems support the energy transition in Germany, as they store electricity from renewable energy sources and make it more efficiently usable. This increases the share of green electricity in gross consumption and reduces the likelihood of having to resort to emergency power from fossil fuels during peak demand periods.
