The ± 800kV ultra-high voltage direct current transmission project for new energy transmission in northeastern Brazil, designed by China Electric Power Engineering Consulting Group Zhongnan Electric Power Design Institute Co., Ltd., held its groundbreaking ceremony at the converter station in Sylvania, Goias state, Brazil. This project is the largest infrastructure construction project in Brazil in recent years, using the world's leading ± 800kV ultra-high voltage direct current transmission technology. The total length of the line is 1468km, with a rated transmission capacity of 5000MW. It is planned to be put into operation in 2029.

The project starts from the Graca Aranha converter station in Maranh ã o state, Brazil and ends at the Silvania converter station in Goias state. China Power Engineering Consulting Group Zhongnan Electric Power Design Institute Co., Ltd. has undertaken the engineering design work for the transmission and reception end converter station, phase-shifting camera system, grounding electrode device, supporting AC station expansion, and DC fiber optic communication system.

After the completion of the project, it will achieve efficient collection and cross regional transmission of clean energy such as wind power, photovoltaics, and hydropower in the northeastern and northern regions of Brazil, greatly enhancing the clean energy consumption capacity of the Brazilian power grid. It is expected to reduce carbon dioxide emissions by about 10 million tons per year. This project is not only a milestone project in Brazil's energy infrastructure construction, but also an important demonstration for the development of ultra-high voltage power grids in South America.
