Rains reduce the use of thermoelectric and hydroelectric plants have a rise in energy generation

With the intense rains in the first four months of this year, the generation of energy delivered by hydroelectric plants to the National Interconnected System (SIN) between January and April was 8.4% higher compared to the same period in 2021. The data was released by the Commercialization Chamber of Electric Energy (CCEE) this Thursday (19).

The CCEE stated that the favorable rainfall conditions reduced dependence on thermal plants in early 2022, which are the most expensive projects in energy generation, and leveraged the use of renewable sources.

According to data collected by CNN on the website of the National Electric System Operator (ONS), consolidated until March 31 of this year, in the first quarter of 2022, a reduction of 69.8% was observed in the generation of electric energy by thermoelectric plants.

While in the first three months of 2021 the country generated 32,796 average megawatts (average MW) for the National Interconnected System (SIN), in the first quarter of this year 22,911 average MW were generated.

The CCEE also pointed out that there was a significant increase in the volume of electricity generated from solar plants and wind farms, when compared to the first four months of last year.

An average of 6,505 megawatts were produced from January to April this year by wind sources, an increase of 7.5% over the same period last year. In the generation by photovoltaic solar, the increase was even greater. There was an increase of 66.8% in the annual comparison.

“The increases can be explained by a more favorable scenario of winds and sunshine in the places that concentrate most of the projects, in addition to the increase in the volume of plants in operation”, explained the chamber in the text released on the results.

Reflections on the electricity bill

The vice-president of the Board of Directors of CCEE, Thalita Porto, emphasizes that this reduction in the use of thermoelectric plants does not necessarily reflect a decrease in energy tariffs. According to her, other factors such as the exchange rate and fuel prices also influence the calculation.

“Regarding the tariff, it is necessary to understand that it is composed of a series of components and not just the hydrological scenario. At the moment, we can say that the cost of generation is lower, but there is still an amount to be paid by all consumers, due to the measures that the sector adopted last year to ensure that there were no problems with the energy supply. , as in fact there was not. Other factors, such as the exchange rate and fuel prices, also influence the calculations”, he highlights.

future scenario

Also according to Thalita, the use of thermoelectric plants should be even lower throughout the year, with the growing participation of thermoelectric and solar plants.

“It is worth noting that, fortunately, the cycle of less rain in Brazil coincides with the favorable period for crushing sugarcane, the main source for generating energy from biomass. In the coming months we will also start a more promising period for the winds in the Northeast, which help to complement the offer”, he points out.

Photovoltaic solar energy continues to develop well, gaining more and more space in the market and taking advantage of all the potential of Brazil, which has good solar incidence practically all year round. All these factors indicate a much more positive year than the last one”, concludes Thalita.
