The cumulative electricity transmitted from ultra-high-voltage (UHV) power projects in Xiliin Gol League, North China's Inner Mongolia autonomous region, surpassed 350 billion kilowatt-hours (kWh) as of June 2, according to State Grid Inner Mongolia UHV Co.

This is equivalent to the annual household electricity consumption of approximately 116 million families. The transmission has also helped save about 110 million metric tons of standard coal and reduce carbon dioxide emissions by nearly 291 million tons.

Blessed with abundant wind and solar resources, Xiliin Gol has become a key clean energy base in northern China. Since the commissioning of the 1,000-kV Xiliin Gol League–Shandong UHV alternating current (AC) transmission project in July 2016, electricity generated on the grasslands has been delivered to provinces and municipalities such as Shanxi, Hebei, Tianjin, Shandong, and Jiangsu.
