State Grid Corporation of China (State Grid)’s subsidiary in Brazil on April 3 inked the concession agreement on the project exporting the ±800-kilovolt ultra-high-voltage (UHV) direct current (DC) new energy power from Northeast Brazil to other regions.
It is the largest power transmission concession project and the largest infrastructure construction project in Brazil in recent years. State Grid won the bid for the project on Dec 15, 2023, its third time to shoulder a UHV power transmission project overseas. The first two projects are also located in Brazil.
The project will include construction of a new 1468-kilometer ±800-kV UHV DC power transmission line, a converter station, phase-shifting transformers, and supporting alternating current (AC) facilities. It is designed with a rated transmission capacity of 5 million kilowatts.
Stretching through the states of Maranhão, Tocantins, and Goiás, the power transmission line will take clean energy like wind, solar, and hydroelectric power from Northeast and North Brazil to the country’s core areas like Brasilia, the federal capital of Brazil, meeting the demands of approximately 12 million people.
The project is scheduled to be put into operation in 2029, with a concession period of 30 years. It is expected to play a crucial role in improving security and stability of Brazil’s power grid, promoting consumption of wind and solar power in Northeast Brazil, and supporting the country’s green and low-carbon economic and social development.
