Vilecha comprises four 50MWp installations spread across 310 hectares. It is expected to generate more than 377GW-hours (GWh) of renewable electricity each year, enough to meet the average annual consumption of around 100,000 people.

Axpo deputy CEO Andy Heiz said: “The Vilecha project reflects our ambition to expand renewable energy across Europe. Large-scale renewable energy can make an important contribution to secure and low-emission energy supply.

“With a capacity of 200MWp, this is the largest PV [photovoltaic] installation in the Axpo portfolio and reaffirms our ability to deliver energy solutions across diverse European markets.”

As Axpo’s largest solar facility, Vilecha provides 83GWh of electricity annually to McDonald’s Spain under a ten-year power purchase agreement.

An additional agreement with Rockwool, starting in 2027, will supply 450GWh over ten years.

The project’s inauguration was attended by Axpo executives, local officials, partner companies, and the Swiss Embassy to Spain and Andorra.

Axpo solar division managing director Antoine Millioud said: “Our sincere thanks to all the teams and partners who helped make this project happen. Vilecha is testament to Axpo’s commitment to expand solar energy and advance the energy transition.

“It also demonstrates that high technical standards and environmental requirements can combine to make a positive impact on the region. In Spain and throughout Europe, we continue to work on providing sustainable energy solutions.”

Vilecha incorporates 365,000 modules on tracking systems, contributing to CO₂ savings of around 75,000t per year.

Construction engaged numerous local professionals, with significant portions of land being publicly owned, directing rental income to municipalities.

Axpo employed sustainability throughout the project, selecting sites with minimal agricultural value, monitoring local ecosystems, supporting pollination, rewilding with native plants and applying circular economy practices.

In April 2025, the company agreed to acquire electricity from two solar power plants in Greece with a combined installed capacity of 102MW.
