Solaria Energía y Medio Ambiente recorded an annual revenue growth of 27% in 2025, driven by 70% growth in the Spanish renewable energy company’s infrastructure business and new capacity coming online. The company is also executing well on its data center strategy as it announced a 213 MW hybrid solar-and-BESS deal in Spain.
Last year, its revenue totaled €303.4 million, while EBITDA of €266.1 million was 32% more on a year-on-year (YoY) basis, and 6% higher than its guidance. Net profit rose by 55% to €137.4 million, it shared.
The Spanish company’s sales from electricity production improved by 12% YoY last year to €197.4 million, despite production falling 4% to 2,434 GWh due to lower solar radiation and prices. It was offset partially by the commissioning of new assets.
Solaria also beat its own guidance of 3 GW operational installed capacity at the end of 2025, finally exiting the year with 3.1 GW, along with an additional 1.3 GW under construction. During the year, it also connected a 72 MWh hybrid battery in Spain.
Its battery energy storage system (BESS) capacity in operation and under construction in Spain reached 1,360 MWh, with a storage development portfolio of 5.1 GW in Europe.
Solaria has also secured environmental clearance to add close to 1 GWh of battery storage at 16 PV plants located in Castilla-La Mancha and Castilla y Leon in Spain, expanding its Spanish BESS with environmental approval to almost 3 GWh.
Solaria previously announced a €2.5 billion renewable energy and BESS investment plan over 2026-2028, with the bulk of it reserved for solar PV, and Spain (see Spain’s Solaria Energía Posts Record Growth In 9M 2025).
Alongside its annual financial results, Solaria announced the signing of a new data center deal with Merlin Properties for the supply of grid access and infrastructure for 213 MW of capacity. The agreement also includes building the necessary electrical infrastructure.
Solaria also entered a 40-year power purchase agreement (PPA) for 426 MW of solar PV capacity and an additional 10-year contract for 600 MWh of BESS with Merlin. These agreements, it explained, give it high visibility of cash flow.
This is its 2nd deal, following a 225 MW deal. However, it is the 1st hybrid solar and battery PPA signed in Spain, it claimed.
Out of its total data center portfolio of 3.4 GW of power secured, the largest of the lot is in Italy with 1.4 GW, followed by 1.2 GW in Germany, 600 MW in the UK, and 200 MW in Germany.
The company expects its data centers to contribute significantly to its revenue going forward. Over the next 5 years, DC-powered services are projected to generate €0.7 billion in revenues for the company, while Spanish DC revenues cover 80% of its infrastructure services targets.
Going forward, Solaria says it has high visibility on the 2026 EBITDA target of €331 million.
