XINING -?China has realized universal power access when connecting the last remote group of 39,800 people were connected to the national grid.

The lights came on Wednesday in Gomang and Changjiang villages in Qinghai province, the last group nationwide without modern lighting.

The 9,614 households are at an average altitude of more than 4,000 meters in the remote hinterland of the Qinghai-Tibet Plateau, said Shi Xueqian, Communist Party chief of Qinghai Power Company.

After a three-year action plan of the NEA, the 39,800 people in Qinghai became the last without power.
