URUMQI - Northwest China's Xinjiang Uygur autonomous region transmitted 43.9 billion kWh of electricity in the first half of 2020, up 53.9 percent year-on-year, according to the State Grid's Xinjiang branch.

A total of 12.1 billion kWh of electricity among the overall transmission volume was mainly generated by wind and solar power, the State Grid Xinjiang Electric Power Co Ltd said.

The company has stepped up regular maintenance and robotic inspection of equipment and transmission lines and conducted emergency drills to ensure the safety of power transmission channels.

The electricity helped reduce 14 million tons of coal use and cut emissions by 37.8 million tons of carbon dioxide, 120,000 tons of sulfur dioxide and 100,000 tons of nitrogen oxides, said Zhang Jun with the Xinjiang Electricity Trading Center.

Xinjiang is rich in coal and wind power resources. According to the Xinjiang Electricity Trading Center, Xinjiang now transmits electricity to 19 other Chinese regions, many of which purchase electricity from Xinjiang as a form of economic support to the region.

In 2019, Xinjiang transmitted over 71.2 billion kWh of electricity to other regions, 1.4 times that of the previous year.
