Liu Zhenya, general manager of State Grid Corporation, announced on the 6th that China will invest more than 500 billion yuan in the next five years to build a "three vertical and three horizontal" UHV AC backbone network and 11 UHV DC transmission projects. The total length of UHV transmission lines will reach 40,000 kilometers, forming a strong grid network for coordinated development of AC and DC.
Liu Zhenya believes that China's repeated tensions in coal and electricity transportation are mainly due to the excessive dependence of energy allocation on coal transportation, and the proportion of transmission is obviously low. The role of power grids in the integrated energy transportation system is still not enough. Therefore, it is necessary to speed up the transformation of the mode of power development and achieve both coal and power transmission, especially the priority of power transmission.
Liu Zhenya made the above remarks at the first mobilization meeting of the world's first UHV transmission line expansion project. He believes that in the next 10 years, China's UHV power grid construction faces major development opportunities. It is estimated that the total electricity consumption and power generation capacity of China's society will reach 6.1 trillion kWh and 1.44 billion kilowatts by the end of the "Twelfth Five-Year Plan", and will reach 7.8 trillion kWh and 1.76 billion kilowatts by the end of the "Thirteenth Five-Year Plan". Both have doubled on the basis of 2009, and the growth space is huge.
He said that with the acceleration of the construction of large-scale coal-fired power, hydropower, nuclear power and renewable energy bases based on wind power and solar power in the west, at the end of the 13th Five-Year Plan, cross-regional inter-provincial power transmission will exceed 400 million kilowatts. There is an urgent need to accelerate the construction of UHV power grids.
The main way to send western energy is the UHV transmission line. Liu Zhenya said that during the "Twelfth Five-Year Plan" period, China will invest more than 500 billion yuan to build a "three vertical and three horizontal" UHV AC backbone network and 11 UHV DC transmission projects.
At that time, wind power and coal power from Inner Mongolia, Shaanxi and Hebei will be sent to North China, Central China and East China through three longitudinal UHV channels; coal power in the north and hydropower in the south will be sent to North China and Central China through three horizontal UHV channels. And the Yangtze River Delta region, ensuring electricity supply nationwide.
