Germany’s battery opportunity - https://ember-energy.org/latest-insights/germanys-battery-op... - May 13th, 2026
- Germany hosts around a quarter of the EU’s total large-scale battery capacity, with over 2.5 GW operational by the end of 2025 – more than double the capacity of just two years earlier. A robust project pipeline and high social acceptance of the technology among German municipalities point to continued growth, with over 10 GW expected capacity, but policy barriers could hold it back.
- If Germany’s expected new large-scale battery projects had been operational in 2025, they could have avoided approximately one-third of wind and solar curtailment, cutting redispatch costs and gas purchases by about €0.8 billion. This exceeds the required investment in batteries.
- Germany’s residential battery market is Europe’s largest and shows prospects for continued growth – roughly one in six homeowners already has a battery installed, and 30% are considering purchasing one within the next five years. Smart charging of these batteries could relieve bottlenecks in the distribution grid and avoid significant system costs.
