500billion will be invested to build UHV transmiss
2022-10-14- Detail
Liuzhenya, general manager of the State Power Corporation, announced on the 6th that China will invest more than 500billion yuan in the next five years to build three vertical and three horizontal UHV AC backbone and 11 UHV DC transmission projects. The total length of UHV transmission lines will reach 40000 kilometers, forming a strong power frame for the coordinated development of AC and DC
Liu Zhenya believes that the repeated tense situation of coal and electricity transportation in China is mainly due to the excessive reliance on coal transportation for energy allocation, the obvious low proportion of power transmission, and the obvious insufficient role of electricity in the comprehensive energy transportation system. Therefore, it is necessary to accelerate the transformation of power development mode and realize the simultaneous development of coal and power transmission, especially the priority development of power transmission
Liu Zhenya made the above statement at the mobilization meeting of the expansion project of the first UHV transmission line in China and the world. He believes that in the next 10 years, China's UHV construction faces major development opportunities. It is estimated that the power consumption and installed capacity of power generation in China will reach 6.1 trillion kWh and 1.44 billion kw respectively by the end of the 12th Five Year Plan, and 7.8 trillion kWh and 1.76 billion kw by the end of the 13th five year plan to enhance industrial upgrading, both doubling on the basis of 2009, and there is a huge room for growth
he said that with the accelerated construction of large-scale coal-fired power, hydropower, nuclear power and renewable energy bases based on wind and solar power in the west, the trans regional and trans provincial power transmission scale will exceed 400million kW by the end of the 13th five year plan, and there is an urgent need to speed up the construction of UHV power
the best way to send energy from the west is to dry it. The way is UHV transmission line. Liu Zhenya said that during the 12th Five Year Plan period, China will invest more than 500billion yuan to build three vertical and three horizontal UHV AC backbone frames 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 vertical UHV channels; We will solve the problem of sending coal power in the north and hydropower in the southwest to North China, central China and the Yangtze River Delta through three horizontal UHV channels at the first time, so as to ensure power supply throughout the country
