Celeo Redes Brasil, S.A. has been awarded Lots 4 and 8 in the latest power transmission auction held in São Paulo. The projects involve new infrastructure designed to strengthen electricity supply and improve the resilience of Brazil’s transmission grid.
Celeo Redes Brasil, S.A. has secured two new power transmission projects in Brazil through Leilão 04/2026, an auction organized by the Brazilian National Electric Energy Agency (ANEEL) and held in São Paulo on October 30. With a combined estimated investment of BRL 4.866 billion (€793 million), the projects involve the construction, operation, and maintenance of electricity transmission infrastructure across several regions of the country under 30-year concession agreements.<br/><br/>
The awards cover Lots 4 and 8, two projects with distinct characteristics and objectives. The first will expand transmission capacity in south-central Brazil to strengthen electricity supply in Mato Grosso do Sul and increase the grid’s capacity to accommodate additional power generation. The second is intended to improve the transmission grid’s ability to withstand the impacts of climate change in the states of Acre and Rondônia.<br/>
New Transmission Lines to Strengthen Electricity Supply in Mato Grosso do Sul<br/>
Lot 4, spanning the states of Paraná, Mato Grosso do Sul, and Goiás, is the largest project Celeo has been awarded through a competitive tender to date, with an estimated investment of BRL 4.113 billion (€670 million). The project has a 60-month construction timeline.
The project includes three 500 kV high-voltage transmission lines. The Rio Brilhante–Sarandi line will extend 310 kilometers and feature a double-circuit configuration, while the single-circuit Chapadão–Rio Brilhante and Rio Verde Norte–Chapadão lines will extend 330 and 217 kilometers, respectively.
The scope of work also includes the expansion of the 500 kV facilities at the Rio Brilhante and Chapadão substations, where transformers with a combined capacity of 3,600 MVA will be installed. In addition, a synchronous condenser will be installed at Rio Brilhante to help maintain voltage stability and support the reliable operation of the transmission grid.
These investments are intended to strengthen electricity supply in Mato Grosso do Sul and increase the grid’s capacity to accommodate additional power generation.<br/>
The project was awarded an Annual Permitted Revenue (Receita Anual Permitida, RAP) of BRL 377.1 million (€61.5 million). Under Brazil’s regulatory framework, RAP determines the annual remuneration the concessionaire is entitled to receive for providing transmission services once the facilities enter commercial operation.<br/>
Greater Climate Resilience for the Acre and Rondônia Transmission Grid
Lot 8 will be developed in the state of Rondônia and has an estimated investment of BRL 753 million (€123 million), with a 42-month implementation period.
Unlike Lot 4, this project focuses on adding new equipment to an existing facility. Specifically, three synchronous condensers, each rated at −200/+300 MVAr, will be installed at the Porto Velho substation and connected to the 500 kV grid. These devices help regulate voltage and maintain power system stability, an especially important function for ensuring reliable electricity supply under challenging operating conditions.
The project aims to strengthen the climate resilience of the transmission grid serving Acre and Rondônia, improving its ability to respond to the effects of weather events and climate change. It was awarded an Annual Permitted Revenue of BRL 66.7 million, equivalent to nearly €11 million.
With these two awards, Celeo expands its portfolio of power transmission projects in Brazil, adding new infrastructure investments designed to increase grid capacity and enhance the security of electricity supply across different regions of the country.
