European solar power purchase agreement (PPA) prices broke four consecutive quarters of decline in the second quarter, with central European countries posting the largest increases as gas prices climbed. Wind PPA prices fell for a fifth consecutive quarter, while hybrid deals gained ground across the continent as storage added measurable value. The figures come from LevelTen Energy's European PPA Price Index for Q2 2026, released on 23 July, which includes hybrid PPA data for the first time.
Opinion: Battery storage is becoming growth infrastructure
Wind PPA prices fell by 1.6 percent in the second quarter, according to LevelTen Energy, which describes itself as the world's largest clean energy marketplace. The market-averaged solar PPA price rose by 2.8 percent, ending a year-long decline. The shift was driven by sharp increases in Germany and Poland, where tighter global gas supply pushed wholesale power prices higher.
Markets tell different stories
"Although the European average price for solar rose this quarter, individual market trends diverge significantly," says Placido Ostos, Director of European Analytics at LevelTen Energy. "German and Polish price rises were substantial enough to lift the European average, even as other markets declined."
Falling solar PPA prices in recent years have reflected strong supply alongside growing negative-price risk, most pronounced in high-penetration markets such as Spain and Germany, where simultaneous solar generation can push wholesale prices to low or negative levels and erode project revenues. The trend is accelerating: France, Germany, Spain and Poland all recorded more negative-price hours in the first half of 2026 than during the whole of 2025.
Negative pricing surges as EU solar outpaces grids
"In markets with severe solar price cannibalisation, two things are occurring simultaneously," comments Ostos. "The first is immense competition between projects amid oversupply. This leads to a second issue: solar PPAs face limited captured prices on the market, forcing developers to offer very low strike prices to appeal to buyers. Both contribute to the downward price slide occurring in several markets."
Why buyers are choosing hybrid
Developers are responding by pairing solar projects with battery storage, unlocking new flexibility in power delivery and additional revenue streams. LevelTen's new hybrid index shows hybrid PPAs priced 24 percent above solar and 15 percent below wind. Settlement values, however, can be significantly higher: in markets such as Germany, adding storage to a solar project can lift captured values by up to 80 percent. That value gap is drawing corporate energy buyers away from standalone contracts. Germany and Spain lead the trend, together accounting for 29 percent of all European PPA offers in the Q2 index, with both countries hosting more hybrid offers than any other deal type, a pattern also seen in Bulgaria, Poland, Latvia, Greece, Lithuania and Portugal.
Storage and co-location seen as remedy for fragile PPAs
"As a country experiencing severe levels of cannibalisation and negative pricing, the market for hybrid PPAs in Germany is substantial," says Pieter van der Meulen, Country Manager for Germany at LevelTen Energy Europe. "We have seen particular traction for so-called Green BESS deals, in which the battery asset can charge only from a co-located renewable generation asset. These structures face far fewer regulatory hurdles compared to batteries with bi-directional grid access, while still providing significant added value for buyers."
"Storage provides many new product types which can alleviate market pressures, enhancing the value of a PPA for both buyers and sellers," adds Ostos. "At LevelTen, we have seen fast-growing market traction for hybrid offers, with the number of new hybrid offers in Q2 more than doubling year over year." (hcn)
