Masdar and Endesa have started construction on a €25.2 million battery energy storage portfolio in Spain the two companies announced through a joint statement reported by the Emirates News Agency. The portfolio consists of three separate battery energy storage systems that together provide 49 MW of power capacity and 98 MWh of energy capacity. The projects are located in the municipalities of Alcázar de San Juan Quintanar de la Orden and Talarrubia within the Castilla-La Mancha region and are expected to enter commercial operation by the end of 2026.
The initiative forms part of a joint venture between Abu Dhabi’s Masdar and the Spanish utility Endesa which is majority owned by the Enel Group. Masdar operates one of the world’s largest renewable energy portfolios with more than 20 GW of projects in operation or development according to company figures. Endesa has deployed multiple energy storage solutions across Spain in recent years as part of its strategy to manage increasing shares of renewable generation on the national grid.
Spain’s government has identified energy storage as a priority within its National Energy and Climate Plan with targets for substantial new capacity by 2030 according to documents from the Ministry for the Ecological Transition. The European Union has similarly emphasised battery systems in its REPowerEU strategy to enhance grid flexibility and reduce dependence on imported fuels a framework the International Energy Agency has tracked in its annual renewable market reports. Global battery storage additions reached a record level last year with Europe accounting for a growing share of deployments according to BloombergNEF data.
The new facilities will deliver grid stabilisation services including frequency regulation and energy arbitrage once operational according to details in the joint venture statement. Such capabilities are increasingly important in markets where solar and wind supply can fluctuate rapidly throughout the day. The projects add to Masdar’s existing investments in Spanish renewables which include solar photovoltaic installations that have contributed more than 200 MW of clean capacity to date according to the company’s project listings.
Construction activities are now underway at all three sites with civil works and equipment installation proceeding in parallel the partners reported. Procurement for the battery systems has already been completed under contracts that prioritise proven technology for long-duration storage. Both companies have committed engineering teams to oversee the build phase and ensure compliance with Spanish grid codes.
Masdar has identified energy storage as a strategic growth area within its international expansion plans which span more than 40 countries. The collaboration with Endesa marks one of several European battery projects the Abu Dhabi firm has advanced in the past two years. Upon completion the portfolio will support Spain’s goal of raising the share of renewables in its electricity mix while maintaining system reliability.
