Construction of the Inner Mongolia section of the West Inner Mongolia-Beijing-Tianjin-Hebei ±800 kilovolt ultra-high-voltage direct current transmission project commenced on March 17 in Togtoh county, Hohhot, capital of North China's Inner Mongolia autonomous region.

The project represents the region's first transmission channel designed to deliver electricity from large-scale renewable energy bases in desert areas to external markets.

Upon completion, it will transmit power generated from a 12-million-kilowatt renewable energy base in the Kubuqi Desert to major demand centers across North China.

Jia Tikang, deputy director of the construction department at State Grid Inner Mongolia Eastern Power Co, said the project will adopt full-process mechanized construction, strengthen on-site safety management, and enhance risk prevention measures to improve efficiency and accelerate progress.

The project is expected to significantly advance the large-scale development and efficient transmission of renewable energy in Inner Mongolia. It will also help the region build an ultra-high-voltage transmission network with outbound capacity exceeding 50 million kW, enabling more efficient allocation of power resources across a wider area.

With substantial investment and strong industrial spillover effects, the project is expected to drive more than 39 billion yuan ($5.65 billion) in related investment and create over 12,000 jobs.

It will involve hundreds of enterprises across equipment manufacturing, survey and design, and construction sectors, fostering technological innovation and supporting the development of a modern industrial system.
