Building more 750-kilovolt-above extra-high-tension power grids
will be the key point of China's 2006-2010 outline on state grid
expansion.
Friday's China Securities Journal unveiled China's future
plan on state grid development between 2006 and 2010, which has
just been finished by the State Power Grid Development Company.
Liu Zhenya, general manager of the State Power Grid Development
Company, said the central government will increase input on state
grid construction in the coming five years in hopes of easing the
bottleneck on power supply and to establish an effective state grid
by 2010.
Liu said a key step to solve electricity-thirst problem in some
areas, the state grid company will pay more attention to
extra-high-tension power grids above 750-kilovolts in the coming
five years, which will be capable of transmitting electricity for
longer distances.
According to Liu, a demonstration project for a 1,000-kilovolt
transmission line will be built in China before 2010, and several
800-kilovoltis transmission lines will also be built in the next
five years.
In addition, a 750-kilovolt power grid will be in shape in the
northwest of China in the coming five years, with a number of
500-kilovolt and 330-kilovolt transmission lines to cover more
regions in demand for electric power, said Liu.
According to Liu, China's first demonstration projects for
750-kilovolt transmission lines have operated smoothly for 100
days, with a total of 250 million kilowatt-hours electricity
transmitted by January 4 this year.
By 2020, China will form three major extra-high-tension power
grids in the north, middle and east parts respectively, and realize
effective distribution of energy resources within the whole
country. Liu said.
