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.
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.
Sustained growth is forecasted in the market for new PV capacity for years to come. Concurrently, battery systems are expected to reach a capacity of at least 100 GWh by 2030, reflecting a transformative shift within the German energy system towards renewable energy integration.
In March 2025, Germany’s largest battery storage system – located in Bollingstedt, Schleswig-Holstein – was connected to the grid. It delivers 103.5 megawatts of power and has an energy capacity of 238 megawatt-hours. The expansion of electricity storage is a key component of Germany’s energy transition.
