Energy Storage Substation for Grid Resiliency and MV Renewable Integration

Iberdrola is installing its first 1,25MW/3MWh Li-ion battery for real operation on the Spanish grid, at the end of a long feeder in the region of Murcia.

The plant is located in an area prone to adverse weather events with difficult accessibility in a confluence of several 20kV lines. In case of an outage, the battery, which will be operational by the end of 2018, will maintain the power supply to the neighbouring villages, deciding automatically the line or lines to be fed by the battery and the size of the electrical island considering the current demand and local generation.
