On the standalone side, the Casal da Cortiça facility in Leiria, developed by Infraventus Energy Storage is Portugal's first fully merchant large-scale battery using lithium technology with a power output of 12 MVA and a charging capacity of 24 MWh. Commissioned in June 2025, it trades energy on the spot and ancillary system services.
Additional hybrid capacity is being deployed, namely by Iberdrola, Greenvolt, Akuo, EDP and GALP, supported by Portugal's Recovery and Resilience Plan (PRR) programme under the “Flexibility and Storage” incentive call. Under this PRR scheme, 41 projects were approved, totalling around 500 MW of new storage capacity and € 99.75 million in grants.
