It targets large-scale energy storage projects in Spain. It focuses on technologies like standalone battery energy storage systems (BESS), pumped hydro energy storage (PHES), and thermal energy storage. The program supports hybrid projects, which combine storage with renewable energy, such as solar or wind farms.

Spanish giant Iberdrola is set to build the €1.5bn Conso II project at Vilariño de Conso near Ourense, Galicia. Is there a dark side to Spain’s green energy revolution?
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.
This allows renewable energy to be used when it is needed. Gravitricity is developing a novel storage technology which offers some of the best characteristics of lithium batteries and pumped storage. Its patented technology is based on a simple principle: raising and lowering a heavy weight to store energy.
Green Gravity uses disused mines to store energy. This allows renewable energy to be used when it is needed. Gravitricity is developing a novel storage technology which offers some of the best characteristics of lithium batteries and pumped storage.
Investing in energy storage helps Spain meet its climate goals. This includes achieving carbon neutrality by 2050. Storing renewable energy instead of wasting it helps the country rely less on fossil fuels. This also cuts down greenhouse gas emissions. Pumped hydro, thermal storage, and battery systems are effective technologies.
