Europe’s Battery Storage Market Crosses 100 GWh as Ukraine Posts Fivefold Growth

Europe installed 36 GWh of new battery storage capacity over the past year, a 48% increase that pushed the continent’s cumulative total above 100 GWh for the first time, according to a SolarPower Europe report. Utility-scale projects were the primary engine of that growth.

Germany held its lead with 6.6 GWh of new capacity, despite growing only 2%. The United Kingdom climbed 64% to 5.2 GWh, while Italy added 5.0 GWh. Ukraine and Bulgaria rounded out the top five at 2.9 GWh and 2.7 GWh respectively.

Ukraine’s result is striking not just for its size — a roughly fivefold jump year-on-year — but for the reason behind it. Across most of Europe, home batteries are bought to trim electricity bills or store surplus solar power. In Ukraine, the calculus is different: households install them to survive grid blackouts. “Ukraine proves that batteries are not just an energy technology, but a resilience technology,” said Vladyslav Sokolovsky, head of the Solar Energy Association of Ukraine.

The market is also spreading geographically. The five largest markets captured around 62% of annual deployments, down from nearly 80% in 2024, suggesting that storage is gaining traction well beyond the traditional leaders. SolarPower Europe projects Europe’s total installed storage fleet could reach between 437 and 735 GWh by 2030.
