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.
Along with the lack of urgency around battery storage on the Spanish grids, key regulatory and market fundamentals have been lacking for the BESS business in Spain. The Spanish market has primarily relied on pumped hydro storage and thermal storage.
Spain is preparing for an unprecedented expansion in battery energy storage and now ranks as the world's second-largest market for project development, behind only the United States.
Battery Energy Storage Systems (BESS) play a pivotal role in supporting the wider adoption and integration of renewable energies (RE) around the world. As a result, the battery technology market is booming with c.$35B+ invested in 2023 – with 70% growth year on year. In Spain, the Energy Storage Strategy aims for 22 GW of energy storage by 2030.
