Northwest China's Xinjiang Uygur autonomous region transmitted more than 71.24 billion kilowatt hours of electricity to the national grid in 2019, up 1.4 times from the figure recorded in 2018 and reaching a record high in history.

According to a statement released by the State Grid Xinjiang Electric Power Co Ltd on its official website, the electricity generated in Xinjiang was transmitted to 19 provinces, autonomous regions and municipalities in the mainland through the national grid, contributing to the country's economic growth.

Xinjiang has constructed a number of high voltage transmission and transfer power stations since 2010 to further increase its capacity to help transmit the rich electricity resources in the region to other parts of the country.

Last year, the Zhundong-Wannan 1,100 kilovolt power transmission project was officially put into operation after three years of construction, adding a new channel for Xinjiang's electricity exports, the statement said.

The 12 million-kilowatt power transmission channel can transmit between 60 billion and 85 billion kilowatt hours of electricity from Xinjiang to East China's Anhui province every year.

Transmitting Xinjiang's rich electricity resources to the national grid to support the economic construction of other provinces, municipalities and regions has helped promote the transformation of Xinjiang's resource advantage into economic advantages and further optimize the region's energy allocation, the statement said.
