On January 14, it was learned from the State Grid Hubei Electric Power Co., Ltd. that the power grid construction in Hubei will invest 32.756 billion yuan this year, providing an important guarantee for the high-quality development of Hubei.
This is a new measure for Hubei power grid to build a stronger distribution network after becoming one of the four provinces and cities in China to realize "no road pulling and no power restriction" last year.
In 2021, due to multiple factors, many provinces and cities across the country will switch off and limit power. In the summer and winter, when the load frequency of the power grid has reached a new high and the contradiction between power supply and demand is prominent, Hubei power grid has also continuously encountered high temperature, flood, wind disaster and tight coal power supply.
In the face of difficulties and challenges, State Grid Hubei electric power carried forward the spirit of "Hubei Electric Iron Army", actively cooperated with coal group to ensure power generation, scientifically prepared an orderly power consumption scheme, made every effort to ensure the safe and stable operation of the power grid, and successively won the key battles of emergency power protection and assistance to Henan and Shaanxi, such as the "May 14" wind disaster in Caidian, the "June 13" gas explosion accident in Shiyan, and the "August 12" flood in Suizhou, Hubei has become one of the four provinces that "do not pull roads and limit power" in China. The power consumption of the whole society has exceeded 240 billion kwh, reaching 247.154 billion kwh, with a year-on-year increase of 15.27%, providing a reliable power guarantee for Hubei to return to the development of the "main track" and realize the "excellence of the whole year" in 2021.
It is reported that in 2021, five UHV projects of "two AC and three DC" in our province have been successfully constructed, of which the Northern Shaanxi Hubei UHV DC project has been completed, the Baihetan Jiangsu, Baihetan Zhejiang UHV DC and Jingmen Wuhan, Nanyang Jingmen Changsha UHV AC projects have completed the progress goals, and the State Grid Hubei electric power has been put into operation for 1556 kilometers of lines above 110 kV The substation capacity is 6.83 million KVA, and the construction of power channel has made important progress.
Li Shengquan, chairman and party secretary of State Grid Hubei electric power company, introduced that this year, Hubei will continue to accelerate the construction of UHV backbone grid, build a 500 kV main grid with "UHV AC and DC stations as the core, three-dimensional and double-layer in Western Hubei and regional clusters in Eastern Hubei", and further optimize the 220 kV grid structure. In addition, the intelligent improvement project of distribution network will be implemented to meet the access of distributed power generation and new loads. Promote the construction of large pumped storage power stations and the multi scenario application of new energy storage, and build a new distribution dispatching system suitable for the development of distributed power generation.
