Pending approval, a total of €167.6 million ($187.1 million) has been allocated toward 46 standalone thermal and electrical energy storage projects, with a cost range from €170/kWh to €409/kWh. From ESS News Spain's Ministry for Ecological Transition and the Demographic Challenge (MITECO) has.
Spain has launched an ambitious €700 million (around $796 million) program to increase its energy storage capacity. This plan will add 2.5 to 3.5 gigawatts (GW) of storage. It includes pumped hydro, thermal energy storage, and battery systems. The goal is to improve how Spain uses renewable energy.
On August 6, 2025, Spain’s Ministry for the Ecological Transition and the Demographic Challenge (MITECO) approved €148.5 million in funding for 199 pioneering solar-plus-storage projects, firmly establishing battery energy storage systems (BESS) as a mandatory component of next-generation renewable.
In December 2022, the government announced a grant-based funding scheme for 600MW worth of storage capacity, which must be combined with renewable power generation (PV Magazine, 2022). The scheme allocated €15 million for each project by a developer and will be valid till December 2025. In late.
The 2023 NECP proposes a 173% increase (or 85 GW) in renewable capacity by 2030 from current capacities1; storage2 is expected to increase by 487%, or 15 GW from installed capacity. Long Duration Energy Storage (LDES) can ensure renewable energy is utilised in the system while decreasing reliance.
First solar plus battery energy storage PPA signed in the Spanish market will allow Zelestra to build a 170 MWdc solar and 400 MWh battery storage hybrid project to supply EDP. The construction of the hybrid project in Trujillo, Extremadura, Spain, will begin in the second half of 2025. This.
