Zelestra and EDP have signed a long-term solar and battery storage power purchase agreement in Spain.
The agreement, the first of its kind in the Spanish market, will allow Zelestra to build a project consisting of 170MWdc of solar capacity and 400MWh of battery storage in Trujillo, Extremadura.
The hybrid product is designed to ensure that the battery can always be fully charged daily by the solar plant in all weather conditions.
Zelestra said this will allow EDP the flexibility to have clean energy outside of “normal solar hours” and at traditionally high-demand, high-price periods of time.
The project will also contribute to reducing the intensity of carbon dioxide emissions during periods of peak power demand, helping to displace gas plants that typically operate during this time.
Zelestra said the total anticipated annual production in Trujillo will be in the region of 300GWh, preventing over 40,000 tonnes of carbon dioxide emissions each year.
