Iberdrola will install six battery energy storage systems (SAEB) in Spain with a combined power of 150 megawatts (MW), as reported this Tuesday by the company, which specified that each battery will have 25 MW of power and a capacity of 50 megawatts per hour (MWh) and will have 37.5 million euros of financing.

The projects will be built in Castilla y León, Extremadura, Castilla-La Mancha and Andalusia and have been recognized as Strategic Projects for Economic Recovery and Transformation (Perte), in its renewable energy, green hydrogen and storage division (ERHA).

Each project will generate more than 100 green jobs, including the construction and operation phases, as highlighted by the company chaired by Ignacio Sánchez Galán.

For Iberdrola, storage batteries are an innovative solution for the integration of renewable energies into the system and allow the use of clean energy to be maximized, regulating the grid frequency in a millisecond and providing backup capacity in periods of highest consumption. .

The batteries will have Lithium-Ion technology, the most widespread today due to its relationship between performance, technological maturity and cost. These systems will be installed as hybrid technology together with renewable energy sources, in this case solar, so the photovoltaic plant and the battery will share the same connection point.

As explained by Iberdrola in a statement, in Castilla y León a battery will be installed in Revilla Vallejera (Burgos), where the company completed its first hybrid wind and solar plant in Spain in 2023.

Extremadura, for its part, will have two new batteries, specifically in the province of Cáceres, where the Campo Arañuelo I and II photovoltaic plants are located.

In Castilla-La Mancha, in the municipalities of Valverdejo, Alarcón and Olmedilla de Alarcón (Cuenca), where Iberdrola has solar parks, two batteries will be installed.

The sixth battery will be built in Huelva, in the municipality of Puebla de Guzmán, where Iberdrola has the Andévalo photovoltaic plant.

“Storage systems are key to addressing the challenge of the energy transition and are destined to become an essential element in the electrical system by allowing the quality of the electrical supply to be improved, ensuring the stability and reliability of the network and integrating and taking advantage of the energy generated by renewable sources”, emphasizes Iberdrola.

The company maintains its commitment to storage through pumped hydroelectric technology, where it has a power of more than 4,000 MW installed in projects such as Cortes-La Muela (Valencia) or Tâmega (Portugal), which with an installed capacity of 1,158 MW is the largest installation of its kind in Europe.
