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.
BESS stands to benefit from the current market dynamics, capitalizing on the opportunity to store energy during low-price periods and release it when prices peak. This arbitrage revenue could redefine the investment landscape for storage in Spain, turning a significant solar challenge into a catalyst for batteries.
Spain's pumped hydro energy storage competes directly against BESS, limiting the battery storage opportunity in wholesale markets. 3. Missing ancillary markets Unlike Great Britain or Texas, Spain never created ancillary service markets that net-zero systems need:
The market energy storage in Spain, particularly in relation to the BESS systems (Battery Energy Storage Systems), is undergoing a dynamic and accelerated evolution. This transformation is driven by the growing need to integrate renewable energy sources into the electricity grid, improve supply stability and optimize energy use.
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.
We expect the Spanish BESS market to take off soon. The expansion of renewable energy will require additional energy storage capacity, and BESS could play a key role. Developments in the regulatory pipeline, market conditions, and the introduction of a capacity market are also enhancing the potential of Spain’s BESS market.
