On the morning of June 30th, local time in Brazil, the construction of the receiving-end Silvânia (GO) Converter Station of the ±800 kV ultra-high voltage direct-current electricity transmission project in the Northeast region of Brazil (the "UHVDC electricity transmission project in the Northeast region of Brazil") implemented by State Grid Brazil Holding, a subsidiary of State Grid Corporation of China, started.

UHVDC electricity transmission project in the Northeast region of Brazil is the largest power transmission concession project in Brazil's history and also the largest infrastructure construction project in Brazil in recent years. This is the third UHVDC transmission project invested, constructed and operated overseas by State Grid Corporation of China, following Brazil Belo Monte UHV transmission Phase I and phase II project. The project will adopt China's advanced and mature ultra-high voltage direct current transmission technology, which will play an important role in promoting the consumption of clean energy in northeastern Brazil and improving the safe and reliable operation of Brazil's power grid. The project is of great significance in serving the sustainable economic and social development of Brazil, deepening the mutually beneficial and win-win cooperation between China and Brazil, pushing the China-Brazil energy and power cooperation to a new level, opening a new "golden fifty years" of China-Brazil relations and building a China-Brazil community with a shared future.

The project includes the construction of 1,468 km (912 miles) of ±800-kV UHV DC transmission lines, converter stations at both ends, and supporting 500kV AC infrastructure, with a rated transmission capacity of 5,000 MW. It will integrate and deliver clean energy (wind, solar, and hydro) from northeastern and northern Brazil, traversing the states of Maranhão, Tocantins, and Goiás to supply approximately 12 million people in regions including the capital Brasília. In December 2023, State Grid Corporation of China secured the project as the sole successful bidder. By April 2024, the company signed a concession agreement with Agência Nacional de Energia Elétrica (ANEEL) and immediately commenced preliminary preparations. After 15 months of environmental licensing and assessment, the receiving-end Silvânia converter station has met all requirements for construction initiation. Scheduled for full completion and operation in 2029, the project holds a 30-year concession term.
