URUMQI, March 20 (Xinhua) -- Northwest China's Xinjiang Uygur Autonomous Region has supplied electricity to 250 million people in 16 provinces and cities across the country.

Xinjiang has supplied 150 billion kwh of electricity, including 34 billion kwh of new energy power, since the region began outbound power transmission in 2010, according to the Xinjiang branch of the State Grid Corporation of China.

In recent years, Xinjiang has invested heavily to improve the region's power grid and guarantee power supplies.

An extra-high voltage power transmission project was launched in 2016. It is expected to be completed in 2018 with annual outbound power transmission capacity of 66 billion kwh.
