en.Wedoany.com Reported - On June 24 local time in Brazil, the full construction of the ±800 kV Ultra-High Voltage Direct Current (UHVDC) transmission project for new energy delivery in Northeast Brazil (hereinafter referred to as the "Northeast Brazil UHV Project") commenced.
The Northeast Brazil UHV Project, independently invested, constructed, and operated by State Grid Brazil Holding, is the largest transmission concession project in Brazil's history. This project is the third UHV transmission project undertaken overseas by State Grid Corporation of China, following the Belo Monte UHV Phase I and Phase II projects. The project was won in December 2023, the concession agreement was signed in April 2024, and the full construction permit was obtained in June 2026, marking the official entry into the comprehensive construction phase. The project is scheduled for full commissioning in 2029, with a 30-year concession period.
The Northeast Brazil UHV Project adopts China's mature and advanced UHVDC transmission technology, constructing a new 1,468 km ±800 kV UHVDC transmission line, converter stations at both ends, and related auxiliary facilities, with a rated transmission capacity of 5,000 MW. The transmission corridor spans four Brazilian states: Maranhão, Tocantins, Goiás, and Minas Gerais. Upon completion and operation, the project will open up a long-distance, high-capacity transmission channel for new energy from Northeast Brazil, breaking the bottleneck for delivering wind and solar power from the region. It will effectively enhance the power supply security of the Brasília capital city circle, help Brazil optimize its national energy resource allocation, accelerate the green and low-carbon transformation of its energy structure, and support sustainable economic and social development.
The Northeast Brazil UHV Project also brings significant ecological and social benefits. The project aggregates clean energy sources such as wind, solar, and hydropower from Northeast and North Brazil, delivering them directly to load centers in the central-eastern region, including Brasília, benefiting the electricity needs of approximately 12 million local residents. Upon completion and operation, it is expected to promote the consumption of over 20 billion kWh of clean energy annually, equivalent to reducing CO2 emissions by 6.84 million tons. The project proactively avoids important natural reserves such as the Jalapão State Park and the Central Plateau Environmental Protection Area; it uses environmental survey modeling to scientifically select routes and sites, avoiding ecologically sensitive areas like natural caves and indigenous territories; it meticulously optimizes tower foundations and construction access designs to reduce the removal of native vegetation by 42.9 hectares; and it plans to implement approximately 953 hectares of off-site afforestation to restore the ecology along the route, minimizing the impact of construction on the local ecological environment. During the construction phase, the project is expected to directly generate over 30,000 local jobs, comprehensively promoting industrial upgrading, improving people's livelihoods, and fostering balanced regional development. Through this pragmatic power project that balances ecological protection, low-carbon emission reduction, and livelihood development, it will empower Brazil's local green and sustainable development in all aspects.
State Grid Corporation of China will fully leverage its advantages in UHV technology and management, adhering to the construction goals of "safe and reliable, technologically advanced, green and environmentally friendly, and world-class," and advancing the project implementation with high standards, high quality, and high efficiency. The full commencement of this project marks another major landmark achievement in China-Brazil practical cooperation. It is a vivid practice of implementing the important consensus between the heads of state of China and Brazil and deeply aligning the high-quality Belt and Road Initiative with Brazil's new "Acceleration Program." This not only injects strong momentum into continuously deepening the China-Brazil comprehensive strategic partnership but also solidifies the cornerstone of energy cooperation for the two countries to jointly create a new "Golden 50 Years" of China-Brazil relations and build a China-Brazil community with a shared future.
