backup power battery project financing options in Spain 2025

Why do we need battery energy storage systems in Spain?

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.

How much energy storage will Spain have by ?

In its National Energy and Climate Plan (NECP), the Spanish government aims to have 22.5GW of energy storage by (see table 1). This amount of storage capacity will be needed to integrate the growing capacity of intermittent generation.

Can energy storage projects get 85% co-financing?

Standalone and renewables-plus-storage battery projects can apply for up to 85% co-financing, along with pumped hydro and thermal energy storage sites. Friday saw the publication of a call for applications for energy storage projects hoping to receive support from a €700 million ($794 million) EU-funded program in Spain.

What is Spain's regulatory framework for energy storage?

Spain’s regulatory framework for BESS is set in its Strategy for Energy Storage. The Strategy identifies the required regulatory measures – such as grid access, market structure, and addressing double tolling – that are currently needed to ensure the deployment of a solid energy storage market.

How much grid-scale storage will Spain have in ?

As of early , Spain has roughly 1 GWh of grid-scale storage under construction, according to industry sources. This new wave of funding could accelerate the build-out, enabling developers, integrators, and OEMs to expand their footprint in one of Europe’s most promising emerging markets.

How much energy storage capacity does Spain have?

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.
