LONDON, May 11 (Reuters) - 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.
