Renewable production supplied 87% of electricity consumption in the first five months of the year and almost 70% in May, according to data released this Monday by REN – Redes Energéticas Nacionais.
From January to May, hydroelectric production supplied 43% of consumption, wind 30%, photovoltaic 8% and biomass 6%, the manager of the national electricity and natural gas system detailed in a statement. Natural gas production supplied 9% of consumption, with the remaining 4% corresponding to the import balance.
Considering only the month of mayRenewable production was responsible for supplying nearly 70% of electricity consumption and non-renewable production 3%, while the remaining 27% corresponded to imported energy.
In the month analyzed, the production of electrical energy from solar energy supplied 12% of national consumption, the highest share ever achieved by this technology.
In the period from January to May, the hydroelectric producibility index registered 1.36 (historical average of 1), the wind producibility index 1.08 and the solar producibility index 0.94.
In May, electricity consumption maintained the upward trend registered in recent months, with an interannual variation of 2.1%, or 3.2% correcting the effects of temperature and the number of working days. Regarding annual accumulated consumption, it registered a year-on-year increase of 2.2%, or 2.7% correcting for temperature and working days.
In the natural gas market, The electric energy production segment was “penalized by the high availability of renewable energy and the significant imports of electric energy”, having registered an interannual monthly reduction of 96%. In the conventional segment, with consumption stabilized, there is a slight year-on-year growth of 0.4%.
In the two segments as a whole, the interannual variation was negative of 27%, with the supply of the national system being carried out “entirely from the LNG terminal [gás natural liquefeito] of Breasts.”
Between January and May, accumulated gas consumption was “the lowest since 2004”, registering a negative interannual variation of 14%.
During the period, the electricity production segment fell 58%, being partially offset by the conventional segment, which grew 4.6%.
