Northwest China's Xinjiang Uygur autonomous region transmitted 10.4 billion kWh of electricity in July, up 57.6 percent year-on-year, according to the Xinjiang Electricity Trading Center.
A total of 3.43 billion kWh of electricity or a third of the overall transmission volume was mainly generated by wind and solar power, the center added.
It is the first time that Xinjiang's electricity transmission exceeded 10 billion kWh in a single month. The expansion is mainly attributed to the upgrading of a key power transfer project that extends from Xinjiang to East China.
Xinjiang is rich in coal and wind power resources. According to the 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.
Since 2010, Xinjiang has transmitted over 300 billion kWh of electricity outside the region through four channels.
