316 MW solar facility will supply clean energy to 155,000 households and cut 75,000 tons of CO₂ annually
€200 million investment created 800 jobs, with extensive use of local suppliers
Project integrates biodiversity conservation, cultural heritage support, and rural development initiatives
Iberdrola España has begun commissioning its Ciudad Rodrigo photovoltaic plant, its second solar facility in Salamanca and one of the largest in Castilla y León. The 316 MW project, developed in partnership with Norges Bank, is set to provide renewable power for more than 155,000 households — more than the population of Valladolid — while avoiding 75,000 tons of CO₂ emissions each year.
The solar farm covers 439 hectares across Valdecarros and Sierra de Torralba, with more than 460,000 panels installed. Iberdrola invested €200 million ($217 million) in the project, creating 800 jobs during construction. Local companies played a central role in the build, from engineering and crane supply to concrete, gravel, and sand.
Through this investment, Iberdrola aims to combine clean energy generation with rural revitalization. The company has committed to restoring Habitats of Community Interest, creating a new pond to strengthen the hydrological network for amphibians, and installing insect hotels, nest boxes for kestrels, and rabbit refuges.
Cultural commitments are also part of the project. Iberdrola has agreed with the City Council of Ciudad Rodrigo to refurbish the main access areas to the Cathedral and has supported the Astróbriga Solar System, a scaled reproduction of the solar system designed to boost tourism and educational outreach.
“With projects like Ciudad Rodrigo, Iberdrola España is not only contributing to the environment and the future but also fostering coexistence by promoting biodiversity conservation, protecting flora and fauna, and supporting cultural heritage and the development of rural Spain,” the company said.
Castilla y León remains Iberdrola’s largest renewable hub in Spain, with 6,297 MW of capacity across solar, hydro, and wind. In solar alone, the company now operates six plants in Palencia, Burgos, and Salamanca, totaling 890 MW. The region also hosts Spain’s first wind-solar hybrid facility, further cementing its role in the country’s clean energy transition.
