BEIJING -- In a blink of eye -- within a span of 0.007 seconds -- electricity generated from China's wind-and-solar-rich Xinjiang Uygur autonomous region was transmitted to the energy-hungry Chongqing municipality, located 2,260 kilometers away.

The State Grid Corporation of China on Tuesday announced the operation of the ±800 kV ultra-high voltage (UHV) direct current transmission project linking Xinjiang's Hami with southwest China's Chongqing.

This marks China's third major project to transmit electricity from energy-rich Xinjiang to other parts of the country.
