Europe’s electricity storage race: Which countries lead in battery capacity?

TL;DR from the article:

• EU battery fleet grew tenfold since 2021, now at 77 GWh
• Grid-scale costs dropped 45% in 2025 alone
• Germany leads at 2.8 GW, Italy second at 2 GW
• France near the bottom despite doubling capacity
• Bulgaria was the surprise breakout market

The 45% cost drop in a single year is striking. Germany and Italy leading makes sense, but France sitting near the bottom is the interesting part given how much flexibility their grid will need as solar keeps growing.
