ENGIE strengthens its energy storage strategy with the development and acquisition of nearly 400 MW in battery systems in Europe. The energy company focuses on electrical system flexibility as a key pillar for integrating renewable energy and improving grid stability.
Energy Storage Projects in Spain
In Spain, ENGIE has acquired two battery energy storage projects with a combined capacity of 278 MW and 1.1 GWh. These facilities, located in Álora and Tarifa, will enable electricity storage for up to four hours, establishing themselves as the largest standalone developments in the country.
Additionally, the systems incorporate synchronous condensers, a technology that provides inertia to the electrical system and enables reactive power management. This technical approach improves grid stability and facilitates greater renewable energy penetration.
Construction of both projects will begin in 2027, while their commissioning will be carried out progressively starting in 2028.
France Advances with Its First BESS System
Furthermore, ENGIE has initiated construction of its first battery storage project in France, located in Castelnau-d’Aude. The facility will have a capacity of 110 MW and 220 MWh, with autonomy of up to two hours.
With these developments, ENGIE exceeds one gigawatt of battery energy storage capacity in Europe, combining operational and under-construction projects across eight countries.
Likewise, the company maintains its target of reaching 95 GW of renewable and storage capacity by 2030. As of the end of 2025, the group already had 57.2 GW installed, reflecting sustained progress in its energy strategy.
According to statements by Paulo Almirante, these projects address the challenge of balancing renewable energy growth with electrical system stability, ensuring reliable and decarbonized supply.
