German energy storage solar power station

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).

Why do people store solar power in Germany?

To date, most battery storage systems in the German electricity system have been used exclusively to optimize self-consumption. Consequently, an exponentially growing number of homeowners and companies store solar power for times when solar generation is low.

How many battery storage systems are there in Germany?

According to preliminary numbers from the German Solar Industry Association (BSW Solar), there were 1.8 billion installed battery storage systems in Germany at the end of last year. They had a capacity 19 gigawatt hours (GWh), enough to cover the daily electricity consumption of two million two-person households.

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.
