Electricity consumption increases by 2.5% compared to 2024

Electricity consumption in Portugal continues to grow in 2025, having increased by 2.5% in the first ten months of the year compared to the same period in 2024 (2% when adjusted for temperature and working days). Consumption in October rose by 1.1% (1.7% adjusted for temperature and working days) compared to the same period last year.

In the natural gas market, the growth trend continued, with a year-on-year monthly increase of 18% in October, sustained by the electricity production segment, which recorded a year-on-year increase of over 100% this month. In contrast, the conventional segment, which covers the remaining customers, recorded a year-on-year decrease of 5.8%. In October alone, natural gas consumption recorded a year-on-year increase of 13%, resulting from 131% growth in the electricity production segment, which offset the 7.7% decline in the conventional segment.

The national system continued to be supplied predominantly through the Sines LNG terminal in October, with the interconnection with Spain accounting for 8%. In the first 10 months of the year, supply came mainly from the Sines terminal, with Nigeria and the US accounting for 48% and 43% of the national system's supply, respectively.

In the electricity segment, between January and October, the hydroelectric productivity index stood at 1.33, wind productivity at 1.00 and solar productivity at 0.89 (historical average of 1). During this period, renewable energy supplied 68% of consumption, slightly below the 72% recorded in the same period last year, broken down into hydroelectric (26%), wind (24%), photovoltaic (13%) and biomass (5%). Photovoltaic energy continues to show high growth, with production 28% higher than in the same period last year. Production from natural gas supplied 15% of consumption, while the remaining 17% corresponded to imported energy.

In October, conditions were particularly unfavourable for renewable production. The hydroelectric component registered an index of 0.64, wind 0.82 and solar 0.93. Renewable production had its lowest share since September 2023, but still supplied 50.2% of consumption. Non-renewable production supplied 18%, while the remaining 32% corresponded to imported energy.
