Iberdrola advances battery storage at the Alcochete and Algeruz solar plants in Portugal

Iberdrola Portugal, a subsidiary of the Iberdrola Group in Portugal, has begun installing battery energy storage systems (BESS) at the Alcochete I and Algeruz II solar plants, located in the district of Setúbal.

The batteries for both projects will provide a combined storage capacity of 180 MWh—100 MWh at Alcochete I and 80 MWh at Algeruz II—and a total output capacity of 45 MW (25 MW and 20 MW, respectively). Together, they will be able to supply electricity for up to four hours to more than 10,000 homes.

This initiative strengthens the electricity system’s ability to integrate greater volumes of renewable energy by storing surplus solar generation and delivering it when demand requires. In addition, the project marks further progress in Iberdrola’s storage strategy as a key enabler of electrification, combining short-duration solutions such as batteries with long-duration technologies like pumped-storage hydropower.
