Overview

• BSW-Solar used the Energy Storage 2025 forum to call for a legally backed target of 100 GWh of operational battery storage in Germany by 2030.
• Germany has about 22.5 GWh in operation as of mid-2025, with residential systems accounting for 18.4 GWh of the 22.7 GWh reported in September.
• An industry survey cited by BSW-Solar found 64% of companies view accelerated and simplified grid connections as the most urgent need.
• The trade body seeks publication of non-binding grid connection information and mandated digitalisation of grid applications, and 45% of surveyed firms support extending grid-fee exemptions for storage beyond current relief running to 2029.
• Across Europe, BESS capacity has climbed from roughly 2 GWh to nearly 22 GWh in five years, yet even projected annual installations of 118 GWh by 2029 would meet only about half of estimated 2030 needs.
