Pioneers in storage systems
At Endesa, we are pioneers in the research and development of large-scale energy storage projects, within our commitment to developing a no-emissions energy model. Our strategy focuses on growth in renewable energy, electrification of demand, energy efficiency, and the phasing out of traditional generation systems and energy storage systems.
Along these lines, in the area of coal plants that are closing we are promoting future plans that include the development of new renewable energy plants and, in the case of the Andorra (Teruel) project, a large-scale energy storage system of up to 159.3 MW.
Among our storage projects, the Carboneras (Almería) thermal power plant system stands out. It is currently the largest in Spain and is based on 20 MW lithium-ion batteries with a production capacity of 11.7 MWh. Another similar one is planned at the thermal power plant that the company owns in As Pontes (A Coruña) and which is currently in the processing phase.
To these initiatives must be added the Store project, the first we developed, based on batteries located on different Canary Islands, which has successfully demonstrated the operation and the possibility of strengthening the grid in isolated electrical systems.
Beyond battery-powered energy storage systems, we also have pump-based storage systems in several hydroelectric plants and we participate in the Gorona del Viento wind-pumped hydro power plant, on the Canary Island of Hierro.
