Otero photovoltaic plant
Iberdrola develops Europe's second-largest photovoltaic plant
Iberdrola projects Photovoltaic energy
Iberdrola has begun proceedings to develop the Otero photovoltaic plant, which, with installed capacity of 505 MW, will be the largest in Castilla y León (Spain) and the second largest in Europe. The plant will be built in the municipalities of Marazuela, Marazoleja and Anaya, in the province of Segovia, and represents an investment of nearly €220 million.
Photovoltaic plant Otero
Iberdrola group continues to lead the promotion of high-capacity renewable projects. After the commissioning of Núñez de Balboa (500 MW), the largest photovoltaic plant currently operating in Europe, and the start of the implementation of the Francisco Pizarro project (590 MW), the company is now starting the procedures for developing the Otero plant, with 505 MW of power.
The project, which will involve an investment of almost 220 million euros, will have a significant local component, which will contribute to boosting the economy and employment in Castilla y León, particularly in the municipalities of Marazuela, Marazoleja and Anaya (Segovia), where the plant will be located. Industrial suppliers will be involved in its development and up to 1,100 people will work in peak periods. The company has also grouped land from 150 local owners, who will also benefit.
Once in operation, the Otero photovoltaic plant will generate enough clean energy to supply 290,000 homes and will prevent the emission of 182,000 tonnes of CO2 per year into the atmosphere.

Iberdrola, world leader in renewable energies
At Iberdrola, we dare committed to renewable energy more than two decades ago as a fundamental pillar on which to build our safe, clean and competitive business model. Thanks to this vision, we are today world leaders in renewables, reaching 44,675 MW of clean energy in operation at the end of the first quarter of 2025.
This commitment is reflected in our Strategic Plan, in which we will allocate €15.5bn gross to renewables. More than half of this amount is focused on offshore wind in the US, UK, France and Germany; 28% on onshore wind and 18% on solar.
