Spanish energy company Naturgy has started construction of its first battery energy storage projects in Spain, advancing its strategy to increase grid flexibility and support renewable energy integration.
The lithium-ion storage systems will be installed at four existing renewable sites — the Tabernas I and II solar parks in Almería, and the Piletas I wind farm and El Escobar solar plant in Las Palmas, Canary Islands.
These developments mark the first phase of a wider programme that will see Naturgy commission 10 battery projects by 2026. Nine of the systems will be hybridised with solar or wind facilities, while one standalone installation will be directly connected to the grid in Vigo, Pontevedra.
The total 160MW/342MWh portfolio represents an investment exceeding €80 million. Once operational, the systems are expected to provide around 125,000MWh of storage capacity annually, equivalent to the electricity consumption of more than 38,000 homes.
Naturgy said battery storage is “key to the security and quality of supply,” adding that it allows renewable energy to be stored and dispatched during periods of low generation to help stabilise the grid and ensure a reliable power supply.
Internationally, Naturgy’s Global Power Generation subsidiary is also expanding its storage portfolio with projects including the ACT Battery in Australia and the hybrid Cunderdin facility, which combines 128MW of solar capacity with a 55MW/220MWh battery system.
