Recently, it was learned from the State Grid Corporation of China's major project construction promotion meeting that the construction of the UHV project of four ACs and four straight lines will be started again in 2022, and the preliminary work of UHV projects such as one AC and five straight lines will be accelerated, so as to strive for early approval and early start of construction.

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%. The total investment in projects currently 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 1,173 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.

UHV construction

From January to July 2022, the construction of Fuzhou-Xiamen, Zhumadian-Wuhan UHV AC will start, and Baihetan-Jiangsu UHV DC will be completed and put into production. During the year, Nanyang-Jingmen-Changsha, Jingmen-Wuhan UHV AC and other 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.

The company will speed up the preliminary work of 6 UHV projects including Datong-Tianjin South Exchange and Shaanxi-Anhui, Shaanxi-Henan, Mengxi-Beijing-Tianjin-Hebei, Gansu-Zhejiang, and Tibet Electricity Transmission to Guangdong DC. The total investment is 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.

At the same time, the State Grid Corporation of China accelerated the construction of ultra-high voltage power grid projects and promoted the coordinated development of power grids at all levels. From January to July 2022, the construction of 1080 110-750 kV projects will start, and 1215 projects will be completed and put into operation. During the year, another 1,002 110-750 kV projects will be put into operation, including 750 kV Qinghai Yuka-Tuosu, 500 kV Henan Shameng and other major projects, and will continue to improve the main grid structure to inject strong momentum into local economic development; Speed up the start of 1,004 110-750 kV projects, including 750 kV Shaanxi Xi'an East, 500 kV Bahrain-Fuxin-Naiman and other major projects to create a large energy transmission channel.

According to statistics, from January to July 2022, the State Grid Corporation of China will start the construction of four pumped storage power stations including Zhejiang Taishun, Jiangxi Fengxin, Hunan Anhua, Heilongjiang Shangzhi, Hebei Fengning, Shandong Yimeng, Jilin Dunhua and Heilongjiang Huanggou. 8 units of 5 pumped-storage power stations including Jinzhai, Anhui, etc. were put into operation, adding 2.45 million kilowatts of installed capacity. During the year, four more pumped storage units will be put into operation in Fengning, Hebei and one pumped storage unit in Jinzhai, Anhui, with an additional installed capacity of 1.5 million kilowatts, and the Zhuanghe pumped storage power station in Liaoning and Niushoushan in Ningxia will be started.

Xin Baoan, chairman and party secretary of State Grid Corporation of China, said that the power grid is an important energy infrastructure with large investment scale, long industrial chain and strong economic drive. State Grid Corporation of China will actively fulfill the three responsibilities and go all out to promote the construction of major projects. , fully release the driving effect of power investment, and contribute to the State Grid's strength to consolidate the trend of economic recovery in China, maintain the economic operation within a reasonable range, and strive to achieve the best results.
