Fotowatio Renewable Ventures (FRV), a leading developer of sustainable energy solutions and part of Jameel Energy, plans to deliver more than 1,200 MW / 5,000 MWh of battery energy storage systems (BESS) in Spain by 2027.
All projects are currently at an advanced development stage and are scheduled to reach Ready-to-Build (RTB) status between 2026 and 2027, strengthening Spain’s position as a strategic market for renewable energy and grid integration solutions.
The portfolio is concentrated in four key regions: Extremadura, Andalusia, Catalonia and Cantabria. It combines hybrid installations — integrating solar PV generation with battery storage — and standalone BESS projects, reinforcing FRV’s role as a pioneer in utility-scale energy storage in Spain.
Extremadura will anchor FRV’s expansion strategy. The region offers high solar irradiation, grid capacity and favourable regulatory conditions for large-scale renewable energy deployment.
Key projects include:
-
San Serván 220 – 56 MW / 225 MWh
-
Solanilla – 18 MW / 72 MWh
Both hybridisation projects are expected to be RTB in Q1 2026, following the approval of Royal Decree 997/2025, which streamlines permitting for storage and hybrid renewable installations.
In addition, the Carmonita cluster will significantly expand hybrid capacity:
| Project | Power (MW) | Storage (MWh) |
|---|---|---|
| Carmonita Ministerio | 320 | 1,360 |
| Carmonita Sur | 80 | 400 |
| Carmonita Norte | 91 | 455 |
| Carmonita IV | 40 | 200 |
| San Serván 400 (hybrid) | 111 | 495 |
| Total hybrid capacity | 652 MW | 3,492 MWh |
This portfolio underscores FRV’s long-term commitment to a region considered one of Spain’s most attractive hubs for large-scale clean energy investment.
In Andalusia, FRV plans to hybridise its Alcores solar PV project (Seville), incorporating 57 MW / 285 MWh of battery storage to enhance operational flexibility and improve participation in Spain’s wholesale power market.
Catalonia will host 334 MW / 1,336 MWh across six standalone BESS facilities located in the provinces of Barcelona, Girona and Tarragona. These projects aim to support grid stability and facilitate renewable energy integration in one of Spain’s most industrialised regions.
Meanwhile, in Cantabria, the Santander BESS Camarreal project will deliver 50 MW / 200 MWh in the municipality of Camargo. Construction is expected to begin in Q2 2026.
Hybridisation strategy to maximise asset performance
A defining feature of FRV’s Spanish pipeline is its focus on hybridising existing and new solar PV plants with battery storage systems. This model enables:
-
Improved renewable energy dispatchability
-
Enhanced grid flexibility and frequency regulation
-
Greater resilience and security of supply
-
Optimised infrastructure utilisation
By combining hybrid renewable projects with standalone BESS installations, FRV aims to maximise asset performance while supporting Spain’s broader energy transition and decarbonisation targets.
The company’s strategy aligns with growing demand for energy storage solutions across Europe, as grid operators seek greater flexibility to integrate increasing shares of renewable energy, manage price volatility and reduce curtailment.
With over 5 GWh of battery storage capacity in development, FRV is positioning itself as a key player in Spain’s utility-scale energy storage market and a contributor to a more resilient and sustainable power system.
