Energy Storage | ACCIONA | Business as unusual

Back

Energy storage technologies are essential to achieving a system based entirely on renewable energies, allowing us to halt global warming and implement a fully sustainable energy model.

ACCIONA has led pioneering initiatives, including the first wind power storage plant in Spain using batteries, located in Barásoain (Navarre), and, in 2021, it connected the first renewable storage facility using recycled batteries at its Tudela photovoltaic experimental park (Navarra).

In 2023, the company consolidated its international leadership with Cunningham, a 190MW energy storage battery with a capacity of 380MWh per cycle, making it the largest of its kind on the Texas grid.

In 2025, the company installed a battery energy storage system (BESS) using recycled batteries from electric vehicles at its Extremadura I-II-III photovoltaic plant in Almendralejo (Badajoz, Spain). The facility features two containers with a combined capacity of 2MW/5MWh, which will store part of the energy generated by the solar plant and optimize its injection into the electricity grid.
