CONSTRUCTION on a west-to-east ultra-high voltage direct current (UHV DC) power transmission project began in east China's Zhejiang Province yesterday, marking the nation's latest efforts to ease power shortages in its eastern regions.
The project, funded by the State Grid Corporation of China (SGCC), will transport about 40 billion kilowatt-hours of electricity annually from Xiluodu Hydropower Station in southwest China to Zhejiang after its scheduled completion in 2014.
This will help save 12.28 million tonnes of standard coal, which means the cut of 34 million tonnes of carbon emissions.
The SGCC, the nation's major power grid operator, will invest 23.86 billion yuan (US$3.79 billion) in the construction .
Starting in Yibin in Sichuan Province, the 1,679.9-kilometer transmission line will traverse Guizhou, Jiangxi and Hunan provinces to reach Zhejiang's central city of Jinhua.
SGCC Vice President Shu Yinbiao said that compared to previous projects, the line will be built with a greater transmission capacity, more advanced technology and a higher domestic manufacturing level.
The move came as China steps up the construction of UHV transmission projects since an increasing number of economically developed eastern cities have reported being affected by power shortages.
The project is the SGCC's third UHV DC power transmission project after the Xiangjiaba-Shanghai and Jinping-Nanjing transmission lines, completed in 2010 and 2012, respectively, said Liu Zehong, director of SGCC's DC power construction department.
The three transmission lines together will support a transmission capacity of 21.6 million kilowatts, Liu said.
These projects will also help fuel the exploration of clean energy in the country's water-rich southwestern regions and make water resources there an economic advantage, which will in turn promote balanced regional growth, Liu said.
By 2015, the SGCC aims to build three north-to-south UHV lines, which would deliver power from the nation's northern energy bases, and three west-to-east UHV lines, which would transport coal electricity from the north and hydropower from the southwest and connect a line among the northern, central and eastern regions.
