Renewables Supplied 54% of Portugal’s Power in August

• Renewables met 54% of Portugal’s electricity needs in August, with hydropower, wind, and solar driving a 71% share from January to August, REN reports.

Portugal continued to strengthen its renewable energy profile last month, with renewables meeting 54% of national electricity consumption in August, according to grid operator Redes Energéticas Nacionais (REN).

The figures highlight the country’s steady march toward energy independence and decarbonisation. During the month, non-renewable sources covered 17% of electricity demand, while the remaining 29% was met through imports.

From January to August, renewables supplied 71% of Portugal’s total consumption, underscoring the resilience of the country’s green energy mix. Hydropower led the way with 30%, followed by wind at 24%, solar PV at 12%, and biomass at 5%. The data shows Portugal’s hydropower resources continue to play a stabilising role, complemented by steady growth in wind and solar output.

Electricity demand also rose. Consumption in August was 3.4% higher year-on-year, and after adjusting for working days and temperatures, the increase was 2.1%. REN noted that despite rising consumption, renewables have been able to cover the majority of the national load for much of the year.

Portugal has long been recognised as a frontrunner in Europe’s renewable transition, driven by investments in solar and wind projects and a commitment to phase down fossil fuel reliance. The strong results of 2025 so far put the country on track to surpass its previous renewable generation records, while also reducing exposure to energy price volatility in international markets.

With more large-scale solar plants under development and offshore wind projects advancing, Portugal is expected to further expand its renewable generation share in the coming years.
