StorSystems
StorSystems is driving the Portuguese energy transition by developing, building, and operating advanced battery storage systems.
As storage proliferates, the probability of demand curtailment events drops sharply, easing concerns for remote workers who rely on uninterrupted connectivity. If everything on the books is built, Portugal will operate roughly 750 MW of batteries by early 2026, rising toward 2 GW by 2030.
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.
For foreigners used to stable northern-European grids, the proliferation of Battery Energy Storage Systems (BESS) promises familiarity: fewer brownouts, fewer dramatic tariff swings, and a growing menu of smart-home contracts that reward households for charging electric cars when surplus solar floods the lines.
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.
