Lasa, April 28 /Xinhua/ — Construction of a section of the ultra-high voltage power transmission line /UHV/ Sichuan-Guangdong began on Tuesday in the city of Chamdo in the southwest of the Sichuan Autonomous Region /SAR, Southwest China/. The line, with a total length of 2681 km, is intended to supply the Greater Bay Area of Guangdong-Shenzhen-Aomen with electricity, utilizing the rich resources of the SAR for the production of environmentally clean energy.
According to the project authors, the total investment volume estimated is 53.2 billion yuan / about 7.76 billion USD, the new ultra-high voltage LEP power transmission capacity of 10 million kW will serve as an important energy artery connecting the SAR and Guangdong Province (Southern China) through Yunnan Province and the Guangxi-Zhuang Autonomous Region.
According to the project schedule, the LEP section in the SAR should reach the established operating capacity by 2028 and will be put into full-scale operation in 2029. It will consist of two high-voltage power transmission lines with a total length of 301.7 km, which will be laid at altitudes ranging from 1900 to 4800 meters above sea level, and two converter stations with capacities of 8 million kW and 5 million kW, respectively.
According to the estimate of the state energy corporation Xizang Electric Power Co., Ltd, after the completion of the project it will annually supply 43 billion kWh of environmentally clean electric energy from Sichuan to the Greater Bay Area and reduce carbon dioxide emissions by 33 million tons.
In recent years, Sichuan has become an increasingly important base for electricity production in China, facilitated by rapidly developing technologies in the field of environmentally clean energy in the country.
By the end of 2025, the total capacity of power units in the USA, including both completed and those still under construction, exceeded 33 million kW, with the installed capacity of already completed projects exceeding 13 million kW.
Construction of the site for the above-mentioned LEP project in Guangdong Province began in September 2025.
