Hybrid Renewable Deals Gain Ground in Europe as Solar-Only Contracts Retreat

Contracts pairing renewable generation with battery storage have moved from the margins to the mainstream of Europe’s clean-energy market. According to data analytics platform LevelTen Energy, hybrid project proposals now represent close to 30% of all offers tracked in its marketplace — up sharply from a period when such structures were a rarity.

The shift coincides with LevelTen’s first-ever publication of benchmark pricing for hybrid power purchase agreements. In the second quarter, the average European hybrid PPA settled at €71.58 per megawatt-hour — higher than comparable solar-only contracts but lower than wind deals.

Meanwhile, the share of purely solar agreements has dropped from a peak of 75% to below 60%, a decline that reflects a structural problem in sun-heavy markets. Aurora Energy Research projects that curtailment volumes will increase by 55% in Spain and 115% in the United Kingdom between 2024 and 2030 as solar capacity outpaces grid flexibility.

Placido Ostos, LevelTen Energy’s director of European analytics, attributed the trend to two converging forces: “Price cannibalisation is hitting solar assets hard. This, together with falling battery costs, makes combining a solar plant with storage a way to recover some of the lost value.”

From a commercial standpoint, the battery element transforms the underlying product. A storage-coupled plant can shape its output profile to match buyer demand — making it considerably easier to price and trade than a standalone generator subject to weather-driven swings. LevelTen regards this flexibility as a key factor behind hybrid deals’ growing appeal to corporate and utility offtakers alike.
