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.
