Chesf in Brazil
GE Renewable Energy's Grid Solutions business was recently awarded its largest ever grid modernization services contract in Latin America by Companhia Hidro Elétrica do São Francisco (Chesf), one of Brazil’s largest electric utility companies. GE will retrofit six of Chesf substations located in the states of Alagoas, Bahia and Pernambuco in northeastern Brazil with its latest state-of-the-art grid technologies.
The contract scope includes the replacement of about 250 circuit breakers and disconnectors, which have been in operation for more than 45 years. GE’s certified field engineers will provide a strategy to assess the condition of Chesf’s high-voltage assets, as well as plan and prioritize the retrofit to propose a suitable solution from both a cost and time perspective.
According to Chesf, the replacement equipment ranging from 69 kV, 203 kV and 500 kV will offer more reliability to support the company’s energy transmission, contributing to improve the quality and access to the electricity supply. Additionally, millions of people will continue to have access to clean and renewable energy in the country, as these installations help transmit power from hydro power plants and onshore wind farms located in the northeast of Brazil to the national interconnected grid (SIN).
“We are pleased to support Chesf in its commitment to modernize its transmission system in this region. GE’s Grid Solutions Services team brings more than just its longstanding expertise in equipment servicing and replacement. Our latest technologies and solutions will help provide Chesf with more operational flexibility and competitiveness,” said Alexandre Ferrari, Commercial Leader of GE’s Grid Solutions for Latin America.
In addition to equipment replacement, GE will offer training to Chesf’s technicians and supply spare part kits for each type of equipment. The entire retrofit process, including additional activities, is expected to be completed in 2025.
