A major power transmission project connecting Shanxi Province's Datong City to Tianjin Municipality in north China has begun construction, the State Grid Corporation of China (State Grid) announced on Tuesday.
As part of China's west-to-east power transmission system, the 1,000kV ultra-high voltage (UHV) AC project spans 770 kilometers, passing through Huailai County in north China's Hebei Province.
The project has a total investment of 23 billion yuan (about 3.18 billion U.S. dollars). Once completed, it will strengthen northern China's power transmission network, significantly improving the security, reliability, and resilience of the electricity supply in the Beijing-Tianjin-Hebei region.
"By 2030, electricity consumption and peak load in the Beijing-Tianjin-Hebei region are expected to increase by approximately 21 percent and 43 percent, respectively, compared with 2024. This project will increase northern China's UHV power transmission capacity to 21 million kilowatts, optimizing the energy supply structure for the region's load centers," said Dan Gang, director of the substation department of the UHV Division under State Grid.
The project will integrate eight million kilowatts of new renewable energy and four million kilowatts of supporting coal power into the grid, helping Shanxi and Hebei to further unleash their potential of energy resources, and accelerate the green transformation of energy.
"The project will facilitate the transmission and consumption of renewable energy generated from Shanxi and Hebei, promoting the consumption of over 14.6 billion kilowatt-hours of clean electricity annually. This will replace 4.45 million tons of coal consumption and cut carbon dioxide emissions by 11.81 million tons each year," said Yan Xiaohong, director of the construction department at State Grid Shanxi Electric Power Company.
