The plant, located in Barasoain (Navarra, northern Spain), is equipped with a storage system consisting of two batteries in separate containers. One is able to maintain 1 MW of power for 20 minutes. The other, a slower-response battery, can maintain 0.7 MW for one hour.
Both lithium-ion batteries feature Samsung SDI technology and are connected to a 3 MW rated wind turbine. They will store energy produced by the wind turbine when required. The turbine is one of five that make up the Barasoain Experimental Wind Farm.
A key element of the innovation work carried out by ACCIONA in this field is the simulation software developed in-house. It means that storage systems can be dimensioned and optimized in synchronization with wind farms, whether they are in the project phase or fully operational.
The installation also has three other units: one for medium voltage cells and analyzers, another for inverters/chargers and a transformer (installed by Ingeteam, a company participating in the project), and a third for the control and monitoring equipment.
The project has received funding from the European Regional Development Fund (ERDF) which manages the Spanish Centre for Industrial Development (CDTI).
