State Grid Eastern Inner Mongolia Electric Power Company conducted inspection and maintenance on switch contacts of its convert station on Sunday in Ordos, Inner Mongolia autonomous region. 

This was part of the annual overhaul of Inner Mongolia's ultra-high voltage (UHV) power grid, making preparations for the upcoming summer electricity peak.

Inner Mongolia, one of China's key energy-producing regions, has built eight UHV transmission channels and support infrastructure, transmitting electricity to Shandong, Tianjin, Shanxi, Jiangsu, and other cities and provinces in China. This forms a north-to-south power transmission network for Inner Mongolia's electricity export.

Inner Mongolia has seen a continuous increase in outbound electricity transmission, with over 690 billion kWh cumulatively delivered through UHV lines, equivalent to reducing standard coal consumption by about 240 million metric tons and carbon dioxide emissions by about 590 million metric tons.

The annual overhaul of Inner Mongolia's UHV power grid is routinely conducted in spring and autumn, involving 168 projects this year. Among them, 105 projects will be completed in the spring session, covering 52 transmission lines and 2,750 sets of equipment.
