Spanish energy firm Zelestra and Portuguese utility EDP have signed what they call the “first” solar-plus-storage power purchase agreement (PPA) in the Spanish renewables market.
Zelestra will build the 170MWp/400MWh solar-plus-storage project in Trujillo, in Extremadura, with construction expected to begin in the “second half” of 2025.
EDP will buy the power produced at the site, though the companies did not clarify the length of the deal.
Zelestra said the hybrid PPA “is designed to ensure that the battery can always be fully charged daily by the solar plant in all weather conditions, allowing EDP the flexibility to have clean energy outside of “normal solar hours” and at traditionally high-demand, high-price periods of time.”

The company has signed solar-plus-storage PPAs in other markets, with a notable 220MW/1GWh deal in Chile earlier this year.
The Spanish deal comes at a significant moment for the country’s energy sector. The blackout in April, which saw much of Spain and Portugal go without power for hours, triggered an investigation and led to headlines blaming solar and other renewables.
This was proven untrue, and the government put the blackout down to oscillation in the system.
