- Zelestra and EDP signed a long-term PPA to develop a 170 MWdc solar and 400 MWh battery storage project in Trujillo, Spain.
- The hybrid plant will produce 300 GWh annually, cutting over 40,000 tonnes of CO₂ and supplying clean energy during peak demand hours.
Zelestra has signed a long-term power purchase agreement (PPA) with Portuguese utility EDP to deliver solar and battery storage power in Spain. The agreement details were disclosed in a statement released on Monday, July 28, 2025.
The deal marks the first PPA in Spain combining large-scale solar generation with battery storage. It will support the development of a hybrid project in Trujillo, Extremadura, comprising 170 megawatts (MWdc) of solar capacity and 400 megawatt-hours (MWh) of battery storage.
Zelestra said the battery system is designed to be fully charged by the solar plant each day, regardless of weather conditions. This will allow EDP to access clean energy during periods of high demand and high market prices, typically outside regular solar hours.
The project is expected to produce around 300 gigawatt-hours (GWh) of electricity annually and avoid more than 40,000 tonnes of carbon dioxide emissions each year by reducing reliance on fossil-fuel power plants during peak demand.
“This agreement enables flexible, clean energy delivery and supports decarbonisation of peak power demand,” Zelestra said in a statement.
