Iberdrola is building the world’s first wind storage battery in Biscay, Spain, which is expected to be operational in January 2022. The project is coming up at the Abadino TS, where the power from the 6MW Oiz wind farm is evacuated. It will have a guaranteed storage capacity of 3.5 MWh, and installation will be handled by Ingeteam. This project complements the country’s first battery storage system, which is located in Elgea-Urkilla in Araba-Euskadi- and has a 5 MW installed power and 5 MWh of storage capacity.

Furthermore, at Spain, the company has built the first battery in Arauelo III, which it is building in the municipality of Romangordo (Cáceres, Extremadura). The project includes a battery with a power output of 3 MW and a storage capacity of 9 MWh, and Ingeteam is in charge of its development. It is also building the Puertollano (Ciudad Real) project, which will contain a lithium-ion battery system with a storage capacity of 20 MWh and will be the first and largest green hydrogen plant in Europe at the moment, powered by a 100 MW photovoltaic plant.

Iberdrola will install batteries with a storage capacity of 12 MW in the Ifara and El Vallito wind farms near Granadilla de Abona, Tenerife, in the Canary Islands. The company has 200 MW of battery capacity under construction or secured, with some already installed, with the goal of increasing to 300 MW by 2025, mostly in the UK and Australian markets. The company’s current battery storage system portfolio totals 900 MW.

REGlobal’s Views: Large energy companies like Iberdrola that have massive clean energy capacities installed or under deployment are now focusing on building energy storage facilities as well to support the grid and balance the intermittent generation from renewables.
