FRV Launches 1200 MW Battery Storage Portfolio to Lead Spain's Renewable Energy Flexibility
Fotowatio Renewable Ventures (FRV), a subsidiary of Jameel Energy, is developing a substantial portfolio of more than 1200 megawatts (MW) of battery energy storage systems (BESS) in Spain. These projects, with an expected readiness to build by 2026-2027, aim to reinforce the countries energy flexibility and renewable energy dispatchability. The portfolio, primarily focused on areas such as Extremadura, Andalucia, Catalonia, and Cantabria, includes hybrid solutions combining photovoltaic (PV) solar and batteries as well as standalone storage facilities.
Currently, Spains installed battery capacity is around 124.5 MW, but forecasts indicate a significant uptick, with more than 740 MW of new projects in planning stages as published in the BOE for 2026. Extremadura emerges as the central hub for this expansion, featuring projects linked to large PV complexes and a major storage cluster. Key projects include San Servan 220 (56 MW / 225 MWh) and Solanilla (18 MW / 72 MWh), both scheduled for construction in early 2026. The primary focus, however, lies in the Carmonita cluster, which encompasses several projects: Carmonita Ministerio (320 MW / 1360 MWh), Carmonita Sur (80 MW / 400 MWh), Carmonita Norte (91 MW / 455 MWh), and Carmonita IV (40 MW / 200 MWh). In addition, plans include 111 MW / 495 MWh for hybridisation of San Servan 400, bringing the total hybrid capacity in this region to approximately 652 MW / 3492 MWh.
The timing aligns with the regulatory framework established under Royal Decree 997/2025, which streamlines permissions and administrative processes for hybrid storage projects. This regulation aims to facilitate project development, allowing for smoother integration into the electrical grid and prioritising hybrid solutions that optimise existing PV infrastructure. In Andalucia, FRV intends to hybridise projects in Alcores (Seville), with 57 MW / 285 MWh of battery capacity. Catalonia will host six standalone storage installations across Barcelona, Girona, and Tarragona, totalling 334 MW / 1336 MWh. Furthermore, the Santander BESS Camarreal project in Cantabria is scheduled to commence construction in the second quarter of 2026, involving a 50 MW / 200 MWh facility.
What unites these projects is a strategic emphasis on hybridisation, particularly leveraging existing PV plants. This approach allows for the optimal use of infrastructure, improving energy dispatch profiles and supporting the integration of higher shares of intermittent renewables. As Spain aims to accelerate its energy transition, such developments are crucial for creating a flexible, resilient, and renewable-dominant system that can meet future demand and decarbonise the grid effectively.
