Iberdrola will enhance Spain's energy storage capacity by installing six BESS units with a total capacity of 150MW. These projects will be located in Castile and Leon, Estremadura, Castile La Mancha, and Andalusia, and will help integrate renewable energy into the national grid.

Each of the six batteries will have a power output of 25 megawatts and a storage capacity of 50 megawatt hours. They will use lithium-ion technology known for its efficiency, maturity, and cost-effectiveness. The BESS device will operate as a hybrid system, paired with solar energy, allowing photovoltaic power plants and batteries to share the same connection point.

These projects have been identified as economic recovery and transformation strategies for the country's renewable energy, green hydrogen, and storage sectors. In Castile and Leon, the Revilla Vallejera factory in Burgos will install one of the batteries, and the company will launch its first hybrid wind solar power plant there in 2023.

Estremadura will receive two batteries, both located in the province of Caseres, adjacent to the existing C Ara ñ uelo I and II photovoltaic power stations. Castile Ramancha will also host two battery events in the cities of Balvedjo in Alarcon and Olmedira de Alarcon in Kunka, where Iberdrola has already operated a solar park. The final battery project will be built in Vilva, Puebla de Guzman, which is the location of the And é valo photovoltaic power plant.

In June 2023, Iberdrola obtained a loan of 1 billion euros from the European Investment Bank to support Europe's energy transition. The company plans to establish a network of 19 solar power plants and three onshore wind farms in Spain, Portugal, and Germany.Editor/XingWentao
