Solar Photovoltaic Plant Castaño Solar

The Castaño Solar photovoltaic plant has been developed by IB Vogt in the province of Segovia, as part of an ambitious project that also includes the plants Serbal Solar, Pato Solar and Baobab Solar, reaching a total power of over 500 MWp combined. Specifically, Castaño Solar has an installed capacity of over 130 MWp of peak power, occupying an area of more than 250 hectares in the municipality of Abades (Segovia).

The main access to the plant is from the CL-605 road, continuing along conditioned rural roads that connect with the town of Valverde del Majano, where some of the project’s auxiliary infrastructure is located. The design and construction were carried out by IB Vogt. The energy generated by the plant is evacuated through a 30/220 kV step-up substation, connected to the transmission network via an underground and overhead evacuation line of approximately 12 km.

A notable aspect of the project is the PPA (Power Purchase Agreement) signed with Apple, whereby the technology company purchases 80% of the energy produced over a 15-year period.

It entered commercial operation in 2024. Castaño Solar is expected to generate around 242,500 MWh annually, enough energy to supply the electricity consumption of more than 73,000 Spanish households, avoiding the emission of approximately 90,000 tons of CO₂ each year.
