China starts UHV power line
The new 700 km UHV line will transmit 8 million kilowatts of renewable energy from Inner Mongolia to Beijing, Tianjin, and Hebei by 2027.

China: China has officially begun construction on a major ultra-high voltage (UHV) transmission project, aimed at moving large volumes of renewable electricity from western Inner Mongolia to the industrial regions of Beijing, Tianjin, and Hebei province.
The direct current line will stretch 700 km and carry up to 8 million kilowatts of power, with operations expected to commence by 2027, according to the project operator, State Grid Corp of China, the world’s largest utility company.
With an investment of $2.5 B (17.2 B yuan), this is the first UHV line in Inner Mongolia specifically designed to support China’s national strategy for large-scale wind and solar generation in the country’s sandy, Gobi, and desert regions.
Ultra-high voltage lines operate at voltages above 800 kV for direct current or 1,000 kV for alternating current, allowing electricity to be transmitted efficiently over vast distances while minimising energy loss.
The project represents a key step in China’s push to integrate renewable energy into its national grid and strengthen the energy supply to some of the country’s most densely industrialised regions.
