Battery Energy Storage System (BESS): In-Depth
What Is BESS? BESS represents a cutting-edge technology that enables the storage of electrical energy, typically harvested from renewable
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.
In March 2025, UK companies Renewco and Atlantica announced the development of up to 2.2GW of BESS projects across Spain. Other projects in the pipeline primarily involve storage co-located with solar or wind generation. According to BloombergNEF, the total capacity currently in the BESS pipeline is around 3GW.
24 June 2025, MADRID — Global energy storage owner-operator BW ESS and Getxo-based energy storage developer Ibersun have signed a joint venture to develop, in its first phase, 2.2GW of utility-scale battery energy storage system (BESS) projects across Spain.
A medium to large utility-scale BESS can provide energy to over 100,000 homes! BESS are installed in a fenced-in, separate area, near a substation or power transmission line, in either 20′ or 40′ shipping containers that are easily removable at end-of-life. During low-demand periods, excess energy is stored in advanced battery systems.
BESS are becoming a key component of the European electricity system, providing much-needed flexibility by storing surplus renewable energy and supplying it during peak demand. However, market conditions for BESS projects vary across countries and continuously change with the progression of the energy transition.
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.
