Facing the clear completion date of the dual carbon goal, the task facing China's power industry is very arduous. On August 3, 2022, it was learned from the State Grid Corporation of China's major project construction promotion meeting that the construction of the "four-interchange and four-direction" UHV projects will be started again within this year, and the preliminary work of the "one-interchange and five-direction" UHV projects will be accelerated to strive for early Approved to start work early.

According to statistics, from January to July 2022, the State Grid Corporation of China has completed grid investment of 236.4 billion yuan, a year-on-year increase of 19%. Currently, the total investment in projects under construction is 883.2 billion yuan, including 3,299 110 kV and above power grids and pumped storage power stations. By the end of the year, it is estimated that nearly 300 billion yuan of grid investment will be completed, and a large number of major projects will be started. The total project investment is 416.9 billion yuan, including 1173 power grids and pumped storage power stations of 110 kV and above. It reached a record high of 1.3 trillion yuan, driving the upstream and downstream industries to invest more than 2.6 trillion yuan.

In terms of UHV construction, from January to July 2022, Fuzhou-Xiamen, Zhumadian-Wuhan UHV AC construction started, and Baihetan-Jiangsu UHV DC was completed and put into production. During the year, Nanyang-Jingmen-Changsha, Jingmen-Wuhan UHV AC projects were completed and put into operation, and the construction of Jinshang-Hubei, Longdong-Shandong, Ningxia-Hunan, Hami-Chongqing DC, and Wuhan-Nanchang, Zhangbei-Shengli and Wuhan-Nanchang, Zhangbei-Shengsheng were planned to start successively. , Sichuan-Chongqing and Huangshi exchange "four crosses and four straight" 8 UHV projects with a total investment of more than 150 billion yuan, further exerting the role of power grid investment in driving.

In the follow-up, the company will accelerate the promotion of 6 UHV projects such as Datong-Tianjin South Exchange and Shaanxi-Anhui, Shaanxi-Henan, Mengxi-Beijing-Tianjin-Hebei, Gansu-Zhejiang, and Tibet Electricity Transmission Guangdong DC. work, with a total investment of about 110 billion yuan. Make every effort to do a good job in the study of the five transmission channels of the large-scale wind and photovoltaic base in the desert and Gobi desert, and plan the project reserve in advance to lay the foundation for further expansion of effective investment.
