According to REN - Redes Energéticas Nacionais, in April, a month with high levels of rainfall in much of the country, hydroelectric production, which uses water from rivers and dams to generate electricity, recorded a productivity index of 1.52 (historical average of 1).

Wind power production also performed well, with an index of 1.10, while for solar energy, the index did not exceed 0.67, despite the consistent increase in the respective installed capacity, REN highlighted.

Non-renewable energy production was responsible for supplying 8% of consumption, while the remaining 2% was supplied by imported energy.

In April, electricity consumption increased by 0.9% compared to the same month of the previous year, or 3.4% when correcting for the effects of temperature and number of working days, and for the period from January to April, consumption grew by 2.3% compared to the same period of the previous year, a figure that remains the same even after correcting for temperature and number of working days.

"This is the highest consumption ever recorded in the national system for this period, 0.8% above the previous maximum recorded in 2010", highlighted REN.

In the first four months of the year, the hydroelectric capability index stood at 1.44, the wind capability index at 1.04 and the solar capability index at 0.74, with renewable production supplying 83% of consumption - distributed between hydroelectric (40%), wind (29%), photovoltaic (8%) and biomass (5%) -, natural gas production 11% and imports the remaining 6%.

In the natural gas market, consumption increased by 4.2% year-on-year, driven by the electricity generation segment, which grew 4.5 times compared to the same period last year.

The conventional segment, however, maintained the downward trend in consumption, with an 11% drop compared to April 2024.
