UHV written into the "Twelfth Five-Year Plan" State Grid strives to add seven lines within the year
04-06
The just-released "Twelfth Five-Year Plan" clearly states that the development of UHV and other large-capacity, high-efficiency, long-distance advanced transmission technologies. Since there were many controversies about UHV construction in the academic circles before, this move not only marks that UHV construction has risen to a national strategy, but also fully clarifies the expectations of UHV construction. "Reassurance". State Grid will actively seek approval for a total of seven UHV lines this year.
UHV rise is
clearly stated in the national strategic outline, to meet the requirements of large-scale cross-regional power transmission and new energy power generation grid integration, accelerate the construction of modern power grid system, further expand the scale of west-to-east power transmission, improve regional backbone power grids, and develop large-capacity UHV. , High efficiency, long-distance advanced transmission technology.
The outline also specifically pointed out in the field of power grids: speed up the construction of large-scale coal-fired power, hydropower and wind power bases for power transmission projects, form a number of cross-regional power transmission channels using advanced UHV technology, and build 200,000 kilometers of 330 kV and above power transmission lines.
A person from the State Grid Corporation of China told our reporter, "Writing it into the '12th Five-Year Plan' means that it has risen to a national strategy, which will create a better external environment for the next step. We are also actively promoting In the past one or two years, there have been signs of power shortage in the eastern region. From the perspective of ensuring power supply and improving energy efficiency, the construction of UHV is particularly urgent.” Bai Jianhua, deputy chief economist of State Grid Energy Research Institute, was interviewed by our
reporter Shi said that this marks the determination at the national level: UHV must be developed! "This is a very good start, but it still needs to be implemented in terms of planning. If you don't take the UHV road, many things will enter a dead end." In his view, if the coal base continues to focus on coal transportation outside the country, it will fall into a There are many problems: insufficient railway coal transportation capacity, excessive road transportation pressure, and too much environmental protection pressure on the user end. Moreover, major power generation companies are facing serious losses in coal power, and the accelerated development of UHV can indirectly solve the problem of skyrocketing coal prices caused by intermediate links.
"In addition, after the construction of UHV lines in several major coal power bases in Northwest China, it is no longer necessary to build transmission channels for wind power alone. Coal-fired power plants in Outer Mongolia can kill two birds with one stone." Bai Jianhua said, "If we build a wind power transmission channel alone, we have calculated that it will cost more than 80 cents per kilowatt-hour to send electricity to the East China grid, which is too expensive."
