Proportion of other investments in Spanish energy storage projects

Due to the large capacity of installed hydroelectric and thermal storage systems and the resilience of the Spanish power grid, the need for Battery Energy Storage Systems (BESS) in Spain has been relatively low. The lack of a clear regulatory framework for BESS has also hindered its development in Spain so far.

EU approved Spain's €700 million energy storage subsidy plan, enabling Spain to deploy large-scale battery storage with co-financing up to 85%.

When it comes to installed energy storage capacity in general, Spain is one of the leading countries within Europe (see figure 2). Currently, Spain has 6.3GW of hydroelectric and 1GW of thermal storage capacity installed. In fact, the non-BESS storage capacity in Spain is higher than in any other European country.

While Spain focuses on large-scale energy storage projects, commercial and industrial (C&I) energy storage remains underserved – a €2.1 billion untapped market (Wood Mackenzie 2024). Our modular commercial battery storage systems offer: ⭐ EU-Compliant Safety Certifications (UN38.3, CE-EMC, IEC62619) ensuring subsidy eligibility.

The projected storage needs of Spain in 2030 are similar to those of the UK and Italy. In its National Energy and Climate Plan (NECP), the Spanish government aims to have 22.5GW of energy storage by 2030 (see table 1). This amount of storage capacity will be needed to integrate the growing capacity of intermittent generation.

Currently, Spain has 6.3GW of hydroelectric and 1GW of thermal storage capacity installed. In fact, the non-BESS storage capacity in Spain is higher than in any other European country. As a result, the need for BESS to integrate renewable energy sources into the electricity system is less immediate than in the UK, for example.
