Lhasa 500kV Transmission Project
The Lhasa 500kV transmission project runs from the Wokha 500kV substation in Sangri County, Shannan, to the Lhasa 500kV substation in Lhünzhub County, Lhasa. It is part of the DC Phase II Expansion of the Qinghai-Tibet Interconnection Project. The DC Phase II was approved by the National Development and Reform Commission in February 2024, with a total investment of 2.603 billion yuan. The route goes through Lhasa and Shannan, covering five districts and counties as of 2024. The project is split into seven bidding packages: six line segments and one substation segment. As a key annual power-supply project for State Grid Tibet Power, it will meet the central Tibet grid’s load, enable transmission of surplus hydro power, and support the electrification of the Qinghai-Tibet Railway, contributing to Tibet’s sustainable development.
