Electricity consumption in Portugal continued to grow in 2025, recording a 2.5% increase in the first ten months of the year compared to the same period in 2024 (2% when adjusted for temperature and working days). In October alone, consumption rose by 1.1% (1.7% adjusted), reflecting sustained demand growth across the energy sector.

In the electricity segment, renewable energy sources supplied 68% of total consumption between January and October, slightly below the 72% recorded in the same period of the previous year. Hydropower led with a 26% share, followed by wind at 24%, solar photovoltaic at 13%, and biomass at 5%. Despite a modest drop in overall renewable share, solar generation continued to show strong growth — up 28% compared to the same period in 2024 — highlighting the technology’s increasing contribution to Portugal’s decarbonisation efforts.

In the natural gas market, the upward trend persisted, with an 18% year-on-year increase in October, driven mainly by the electricity production segment, which recorded a surge of more than 100% during the month. Conversely, the conventional segment, covering all other customers, saw a 5.8% annual decline.

Portugal’s national energy system continued to be supplied predominantly through the Sines LNG terminal in October, with Spain accounting for 8% of interconnections. Over the first ten months of 2025, supply came mainly from the Sines terminal, with Nigeria and the United States representing 48% and 43% of total imports, respectively.

In October, however, unfavourable weather conditions reduced renewable productivity, with hydropower, wind, and solar indices standing at 0.64, 0.82, and 0.93 respectively (historical average: 1). As a result, renewables covered 50.2% of monthly consumption — their lowest share since September 2023 — while non-renewable sources supplied 18% and imported electricity accounted for 32%.
