Iberdrola has switched on a multi-megawatt battery energy storage system (BESS) in rural Spain that will enable up to five hours of backup power to local networks in the event of an outage.

Clean energy firm Holaluz has completed Spain’s first shared self-consumption solar PV and battery storage facility on a house near Barcelona.

In less than a week, more than 180,000 Spanish citizens have signed a petition against plans for a new ‘sun tax’ on use of batteries for residential self-consumption of solar energy in Spain.
