German battery energy storage: a key technology for grid integration? While Germany's new coalition government has made the right noises about energy storage in its written agreement, the lack of concrete reform and legal certainty in the terms used is not enough for investors to bank on.
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).
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.
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.
