FRV is developing a 1.2GW/5GWh battery energy storage system portfolio in Spain, targeting 2026-2027 for 'shovel-ready' projects. The initiative focuses on hybridising existing PV plants and standalone BESS across Extremadura, Andalusia, Catalonia, and Cantabria.

Extremadura will see key projects like the San Serván 220 complex (56MW/225MWh) and the Carmonita cluster (totaling 652MW/3,492MWh). In Andalusia, 57MW/285MWh will be added to the Alcores projects, while Catalonia will feature 334MW/1,336MWh across six sites.

The Santander BESS Camarreal project in Cantabria will provide 50MW/200MWh, with construction starting in Q2 2026. The rollout is facilitated by Spain's Royal Decree 997/2025, promoting energy storage integration.
