China commenced the construction of an ultra-high voltage direct current transmission line linking two provincial-level regions, according to the State Grid Corporation of China.

Stretching a total of 1,634km, the electricity transmission project starts in Northwest China's Ningxia Hui Autonomous Region and ends in the central province of Hunan. It passes through six provincial-level regions across the country. Once completed, this transmission line is estimated to supply electricity of over 36 billion kWh per year to Hunan, a province with a strong demand for power to sustain its economic growth, according to the company.
