BEIJING Aug 13 The State Grid Corporation of
China plans to start building two more ultra high voltage (UHV)
power lines this year after its second pilot UHV line was put
into operation last month, a company newspaper said on Friday.
All preparatory works for the Huainan-Wannan-Shanghai line
and Xilingol League-Nanjing line have been completed and
construction will start after other relevant conditions are
ready, Sun Xin, head of the UHV department under the grid, was
quoted as saying by the State Grid News.
Sun did not disclose possible investments or line capacity.
The Huainan-Wannan-Shanghai line is part of the firm's
alternating current loop line plan in the Yangtze river delta,
while the Xilingol League-Nanjing line, along with
Zhangbei-Nanchang and North Shaanxi-Changsha lines, make up its
plan of three longitudinal UHV alternating current lines that
would send power from northern China to southern regions.
The company has also planned three horizontal alternating
current UHV lines: West Inner Mongolia-Weifang, Central
Shanxi-Xuzhou and Yaan-southern Anhui, in addition to 11 UHV
direct current lines, all set for completion by the end of 2015.
The leading grid operator in China started running the
world's first 1,000-kilovolt alternating current power line
linking northern Shanxi province and central Hubei province in
January 2009 and began operating the 800-kilovolt direct current
power line last month that sends hydropower from western Sichuan
to Shanghai in the east.
Sun said construction of the firm's third UHV line, the
Jinping-eastern Jiangsu direct current line, was proceeding well
China has planned to spend 300 billion yuan ($44.3 billion)
by 2012 on UHV power lines, fast-tracking an ambitious plan to
boost trans-regional power supply capacity.
Different from those in the United States and other
countries, the State Grid Corporation of China regards UHV lines
as the backbone for its future smart grid networks.
China Southern Power Grid Co, the smaller of China's grid
duopoly, also put into operation an UHV direct current line
earlier this year.
