Acciona Energía has opened the wind power storage plant with batteries that the company has put into service in Barásoain (Navarra). It is the first facility of its type incorporated into a grid-connected wind farm in Spain.
The plant in Barásoain is equipped with a storage system that consists of two batteries located in separate containers: one fast-response battery of 1 MW/0.39 MWh (capable of maintaining 1 MW of power for 20 minutes) and other slower-response battery with greater autonomy (0.7 MW/0.7 MWh, maintaining 0.7 MW for 1 hour). Both have Samsung SDI Li-ion technology connected to a 3MW AW116/300 wind turbine of Acciona Windpower (Nordex Group) technology, from which they will capture the energy to be stored. The wind turbine is one of five that make up the Experimental Wind Farm at Barásoain, operated by the company since 2013. Storage solutions will be applied in the plant aimed at improving the quality of the energy sent to the grid. Acciona has developed its own control software for the plant, plus a simulation program that can dimension and optimise storage systems for integration into wind farms.
