On July 18, the 110kV power transmission project connecting Ceke Substation in Ejin Banner, Alxa League, Inner Mongolia Autonomous Region to Nariin Sukhait Substation in Mongolia was energized, signifying the full commissioning of Inner Mongolia’s first 110kV transmission line to Mongolia.
The project was jointly developed by the Mongolia Power International Cooperation Corporation and the Alxa Power Supply Company of Inner Mongolia Power (Group) Co., Ltd., and Mongolia’s Nariin Sukhait Electric Power Company. At Ceke Port in Ejin Banner in China, a new 110kV substation feeder bay and 19.5 kilometers of overhead transmission lines were constructed. Meanwhile, in Mongolian’s South Gobi province, a new 110kV substation and 40.8 kilometers of overhead transmission lines were constructed in the Nariin Sukhait area.
To ensure the smooth operation of the line, the three parties held regular consultations. They addressed the unique challenges of cross-border power transmission, took into account relevant policies and regulations, and proposed practical solutions.
During construction, over 40 Chinese technicians ventured deep into the Gobi Desert to complete equipment debugging, conduct emergency drills, and deliver three cross-border technical training sessions. They provided technical support to Mongolian counterparts and trained local technicians, thus laying a solid foundation for grid security.
The Nariin Sukhait region in Mongolia’s South Gobi Province is rich in mineral resources but has long suffered electricity shortages. However, with the recent activation of a new transmission line, the region anticipates a twofold increase in power supply. This development is set to alleviate production constraints in mining operations and benefiting thousands of herder households in surrounding areas. The provision of reliable electricity is fostering growth in local extractive industries and promoting synergy between China’s Belt and Road Initiative and Mongolia’s “Steppe Road” program.
Since inaugurating China’s initial power line to Mongolia in 1994, the Inner Mongolia Power (Group) Co., Ltd. has expanded its operations to manage nine transmission lines along the China-Mongolia border within the Western Inner Mongolia grid.
