Naturgy has begun construction of its first battery energy storage projects in Spain as part of its strategy to strengthen grid flexibility and support renewable integration.
The lithium-ion systems will hybridise the company’s Tabernas I and II solar parks in Almería, and the Piletas I wind farm and El Escobar solar plant in Las Palmas, Canary Islands.
The company said these four sites mark the first phase of a broader programme that will deliver 10 battery projects by 2026 – nine hybridised with wind or solar plants and one standalone system directly connected to the grid in Vigo, Pontevedra.
The combined 160MW/342MWh portfolio represents an investment of more than €80m and will provide around 125,000MWh of storage annually, equivalent to the power needs of more than 38,000 homes.
Naturgy said battery energy storage systems are “key to the security and quality of supply”, enabling stored renewable energy to be dispatched during low production periods to stabilise the grid and ensure reliable supply.
Internationally, the company’s Global Power Generation subsidiary is expanding its battery portfolio with projects such as the ACT Battery in Australia and the hybrid Cunderdin facility, which combines 128MW of solar capacity with a 55MW/220MWh battery system.
