6 FAQs about [Expected ROI of utility scale ESS project in Spain 2025]
How much energy storage will Spain have by 2030?
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.
Why should Spain invest in a Bess fleet?
In addition to stabilising the energy grid, the expansion of Spain’s BESS fleet will also prevent energy from being wasted, when supply exceeds demand. The joint venture, targeting greenfield, four-hour duration assets, will progress an initial 2.2 GW pipeline of eight projects across Spain.
Does Spain need a Bess energy system?
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.
How many Bess projects are there in Spain?
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.
Why did BW ESS move to Spain?
For BW ESS, a firm with a growing global portfolio across the UK, Australia, and other parts of Europe, the move into Spain is a calculated one. “We have a common objective to improve Spain’s grid resilience and support the market’s ambitious energy storage growth targets,” said Isaac Garcia Moreno, Executive Director of BW ESS.
How many greenfield projects will bw ESS have?
