European renewable projects with batteries set to grow more than 450% by 2030

Europe's co-located renewable power and battery capacity is expected to surge more than 450% by ​2030, with Germany the most attractive country ‌to build projects, a report by Aurora Energy Research showed on Monday.

• Renewable projects such as wind and solar in Europe ​are increasingly being developed with battery storage ​alongside them which allows generators to store power ⁠rather than sell it at a loss when ​there is excess on the system, and then discharge ​the power when prices recover.
• Europe's co-located renewable capacity reached 6.3 GW in 2025, led by solar-plus-storage which made up over ​60% of deployments, the report said.
• This is expected ​to grow to around 35 GW by 2030.
• Germany was ranked as ‌the ⁠most attractive region for these projects due to higher expected returns on investment, followed by Britain and Bulgaria.
• Spain, Hungary and France were flagged as markets to ​watch amid ​ongoing regulatory ⁠reform.
• Across Europe, negative price hours surged in 2025, with Spain, the Netherlands and ​Germany each exceeding 500.
• Curtailment- when output from ​renewable ⁠plants is curbed to protect the grid when supply exceeds demand - is forecast to rise from over 10 ⁠terawatt ​hours in 2024 to around 33 ​TWh by 2030, the report said.
• The report covered Europe's 20 main ​power markets.
