Iberdrola Inaugurates The First Battery Storage Plant Connected To The Distribution Network In Spain

Iberdrola has launched a multi-megawatt battery energy storage system (BESS) in rural Spain that will allow up to five hours of backup power to local networks in the event of a blackout.

i-DE, the electricity distribution arm of the electricity company Iberdrola, has deployed a 3MWh battery energy storage system (BESS) in the municipality of Caravaca de la Cruz, in the Murcia region.

They claim that it is the first grid-connected lithium-ion battery distribution project in Spain. In addition to improving the quality and reliability of power in the local area, it will also help the integration of solar photovoltaic (PV) resources .

In addition to improving the quality and productivity of local energy, Iberdrola affirms that the system can also operate in isolation. In the event of a natural disaster or other cause of power outage, the facility can provide up to five hours of electricity to Caravaca de la Cruz, as well as four other nearby municipalities, according to Iberdrola.

Iberdrola said that the Caravaca de la Cruz project includes an intelligent controller for the interaction of the battery with several nearby photovoltaic plants and adjusts the voltage of its output. In addition to intervening in the event of a power outage, it can also determine day by day “which part of the grid” can run on the battery, taking into account the state of charge, photovoltaic production and the characteristics of local electricity consumption in a Given moment.
