Auction contracts 29 new clean energy plants, with an investment of R$ 7 billion

The A-4 new energy auction, held this Friday (27), to meet the demand of distributors in the regulated market, contracted 947.9 average megawatts (MW) from 29 plants, all with production from renewable sources.

Together, they will add a total power of 948 MW to the National Interconnected System (SIN). The average discount was 9.36% in relation to the initial price.

The auction, promoted by the National Electric Energy Agency (Aneel) and the Electric Energy Commercialization Chamber (CCEE) lasted just over an hour and attracted the interest of only three distributors: Cemig (MG), Coelba (BA) and Light (RJ).

The companies purchased energy from 18 smaller hydroelectric plants, five solar photovoltaic generation plants, four wind farms and two biomass-fired thermal plants.

It was the first time that solar and wind sources competed simultaneously in an auction. Secretary of Planning and Strategic Development of the Ministry of Mines and Energy, Paulo César Domingues highlighted that, although the discount was lower than the standard found in previous auctions, the result was positive due to the international situation.

“It was already an intention to make sources (wind and solar) compete with each other and we perceived an approximation of prices between the two. The result shows a balanced distribution. The War in Ukraine has demanded a lot from these two sources, all countries have hired a lot. So we expected even a smaller discount,” he says.

Director of Electric Energy Studies at the Energy Research Company (EPE), Erik Eduardo Rego understands that the discount, although smaller, was not a hindrance to the process.

“It is not a cause for concern. The price only worries if it is a barrier, and it was not a barrier. I don’t get too attached to the discount, what matters is the final result, and the final result would not be different”, evaluates the director of the federal agency.

According to Aneel’s projections, the discount achieved will generate savings of around R$ 1 billion and avoid a tariff increase of around 0.5 percentage point.

The investments are spread over seven states: Minas Gerais, Mato Grosso, Mato Grosso do Sul, Paraná, Rio Grande do Sul, Santa Catarina and Tocantins.

Winning projects, all new, must start energy supply on January 1, 2026.
