Inner Mongolia's outbound power transmission exceeds 300b kWh

In 2024, Inner Mongolia autonomous region, one of China's key energy-producing regions, transmitted 315 billion kilowatt-hours of electricity to other provinces and municipalities, securing its position as the nation's top electricity exporter. This strong momentum has continued into 2025, with the region achieving a new milestone in ultra-high voltage (UHV) power transmission.

As of March 3, Inner Mongolia had delivered 302.85 billion kWh of electricity via UHV grids to North China, East China, and Central China, representing an 11.01 percent year-on-year increase, meeting the annual power demand of nearly 30 million people.

Ye Ligang, general manager of the Ultra and Extra High Voltage Branch of State Grid Inner Mongolia Eastern Electric Power Co, highlighted the region's consistent expansion in UHV transmission capacity. Over the past seven years, Inner Mongolia has maintained uninterrupted growth in outbound electricity transmission, with 2024 alone recording 170.6 billion kWh through UHV lines.

To support large-scale power delivery, Inner Mongolia has established eight UHV transmission corridors linking it to Tianjin municipality, as well as Shanxi, Shandong, and Jiangsu provinces, forming a robust north-south power transmission network.

As part of China's 14th Five-Year Plan (2021-25), four new UHV direct current projects are in development. These projects will enhance connectivity between western Inner Mongolia and the Beijing-Tianjin-Hebei region; Kubuqi and Shanghai; Tengger and Jiangxi; and Ulan Buh and the Beijing-Tianjin-Hebei-Shandong region.

Currently, 12 additional UHV projects are in the pipeline, marking the beginning of a new phase of rapid UHV expansion in Inner Mongolia.
