November 26 (Renewables Now) - i-DE, the power distribution unit of Iberdrola SA (BME:IBE), has deployed a 3-MWh lithium-ion battery storage system for distribution networks in the rural municipality of Caravaca de la Cruz in Spain’s southeastern region of Murcia.
Iberdrola said the new storage system can operate in island mode and supply up to five hours of electricity to local townships in the event of power failures.
Caravaca de la Cruz was chosen for having several solar photovoltaic (PV) parks operating in the area, whose size can cause the voltage to rise in the distribution network during high sunshine periods. The battery is capable of adjusting the voltage to appropriate values and is equipped to act as a second source of power when failures occur, the Spanish company added.
The battery system also serves as an alternative solution to the area’s distribution failures caused by harsh weather events happening in recent years. The traditional solution would have had to involve the construction of new power lines through the protected environment in an area made up of small and dispersed communities. The company said it opted to serve this population with a single smart battery to improve the continuity of the power supply in emergency situations and make use of the local PV parks.
