State Grid Corporation of China revealed on the 26th that the total investment in the power grid for the whole year will exceed 600 billion yuan for the first time, with an increase of 71.1 billion yuan over last year. It was reported that this year's new investment will mainly be used for the construction of ultra-high-voltage AC/DC projects, strengthening the connection between county-level power grids and the large power grid, upgrading the digital and intelligent power grid to better guarantee power supply, promoting the output of large-scale wind and solar power bases in western regions, and improving disaster prevention and relief capabilities and service quality for people's livelihood.

Ultra-high-voltage technology has become a key technology for the consumption of new energy power due to its ability to transmit power over long distances on a large scale. It has become an important direction for power grid investment in a new round of power system reform and energy transformation. Zhou Xuhui from Dongfang Securities stated that the incremental expectation of ultra-high-voltage DC projects will be brought about by the external demand generated by the new energy installation plan. Considering only the 315 GW external demand generated by the Shaogou Desert wind and solar power base during the 14th-Five and 15th-Five periods, the corresponding number of new DC transmission lines needed reaches 30. Based on this calculation, 4-5 new DC ultra-high-voltage transmission lines will be needed every year in the future, corresponding to an annual investment of about 25 billion yuan in the core equipment for DC ultra-high-voltage transmission. Yang Rensi from Guosheng Securities believes that if 33-41 transmission lines are needed for the corresponding external demand of 455 GW wind and solar power bases, there are still 26-34 lines that need to be built, and the construction gap is large. Some research institutions believe that the future ultra-high-voltage market demand is expected to reach nearly trillions of yuan.

According to the Financial Data Center, among related listed companies:

China XD Electric maintains a leading position in the industry in terms of market share in ultra-high-voltage. The company and its eight subsidiaries won a total bid of 4.739 billion yuan for Jinshan-Hubei and Ningxia-Hunan ±800kV ultra-high-voltage DC transmission projects.

XJ Electric Co., Ltd. has formed an ultra-high voltage business system consisting of 1100 kV and below ultra-high-voltage DC transmission, 800 kV and below flexible DC transmission, DC transmission maintenance and experimental services, etc. for the electrical utilities industry.
