In March, renewable energy sources in Portugal performed exceptionally, covering 88% of the national electricity consumption, according to the latest data from REN (Redes Energéticas Nacionais). This remarkable result is largely attributed to very favourable weather conditions, which boosted the production of hydroelectric, wind, and solar energy. l4w2y

Hydroelectric power stood out in particular, with a productivity index of 1.86, well above the historical average of 1. Weather conditions, such as rainfall and snowmelt, favoured power generation from reservoirs, consolidating it as one of the most significant energy sources of the month. Additionally, wind energy achieved a productivity index of 1.07, and a historic milestone was reached when the highest wind energy peak ever recorded was ed, with 5,078 MW on March 19.

Meanwhile, solar energy, while continuing to show strong growth, remains a smaller part of the energy mix, ing a productivity index of 0.71. Nevertheless, photovoltaic energy continues to make a significant contribution to the expanding system.

In of electricity consumption, the first quarter of 2025 saw the highest consumption on record, reaching a total of 14.1 TWh, suring the 13.9 TWh recorded in the same period in 2010. Compared to the first quarter of 2024, consumption increased by 2.7%, with a 2.8% year-on-year growth in March.

During the first three months of the year, renewable energy ed for 81% of total electricity consumption, with hydroelectric energy leading production (39%), followed by wind energy (29%), solar energy (7%), and biomass (5%). As for non-renewable energy, natural gas covered only 12% of consumption, while electricity imports from abroad ed for the remaining 7%.

This outlook reinforces Portugal's commitment to energy transition, highlighting the growth of renewable energy and the consolidation of a more sustainable and efficient energy system.
