Masdar and Endesa have started construction on three battery projects in Spain, with 120.34 MWh of planned storage and €9 million in public financing calculated from Endesa’s project figures.
The systems are planned to provide 60.16 megawatts (MW) of power capacity. Ardila, in Fregenal de la Sierra in Badajoz province, is designed for 36.10 MW and 72.20 MWh, alongside an existing 44 MWp solar plant. La Vega I and La Vega II, in Teba in Málaga province, are each planned for 12.03 MW and 24.07 MWh.
Endesa values Ardila at €14.3 million, including €4.6 million in public financing. The La Vega projects account for €10.9 million, including €4.4 million in public financing. Those two amounts add up to €9 million across the portfolio; total project investment is €25.2 million.
The systems will use lithium iron phosphate batteries and grid-forming inverters. Masdar says the technology can provide synthetic inertia and respond quickly to sudden grid changes. “These projects will help integrate more clean power into the grid,” said Dr. Ibraheem Almansouri, Masdar’s acting chief operating officer.
Masdar estimates construction will involve 50 jobs. Endesa expects peak workforces of 25 at Ardila and 25 across the two La Vega projects. Endesa said the projects were selected through a grant call for storage paired with renewable generation.
The developments are the first storage projects under the Masdar-Endesa partnership. Endesa said Masdar completed its acquisition of a 49.99% stake in the company holding a 2-gigawatt portfolio of Endesa’s operating Spanish solar assets in December 2024. Endesa retained control and asset management.
Spain’s updated National Integrated Energy and Climate Plan targets renewable sources for 81% of electricity generation by 2030 and sets a 22.5-gigawatt storage target. The companies expect all three systems to be operating by the end of 2027.
