Their simulations show that combining solar, wind and at least four hours of battery storage can meet Portuguese demand in 94 % of hours across an average year; add pumped hydro and that rises above 99 %. The remaining gap could be filled by green hydrogen or demand-response contracts that pay factories to pause production when clouds linger.
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.
In the period from January to August 2025, Portugal generated 33,107 GWh of electricity, with renewables accounting for 76.9% of total generation—the fourth-highest share in Europe, following Norway, Denmark, and Austria.
Battery Energy Storage Systems (BESS) are emerging as a foundational technology for modernizing the electric grid, offering fast, flexible, and scalable solutions to support renewable integration and ensure grid reliability. As costs decline and policy support grows, BESS is poised to play a. . It's a common misconception that the electricity grid operates like a vast reservoir of power, storing energy and delivering it on demand. The reality is a far more precarious balancing act.
