Recently, there have been constant news about ultra high voltage tenders. Against the background of the construction of a new power system, the construction of ultra high voltage is expected to continue to advance. Galaxy Securities' research report pointed out that the previous peak investment in ultra high voltage generally lasted for about 2 years, but this round of peak is optimistically estimated to exceed 5 years. It is expected that there will be about 27-32 new direct current transmission channels for external transmission during the "14th Five-Year Plan" and "15th Five-Year Plan" period, with a stock of 4 lines, 5 under construction, and a gap of 18-23 lines.
Recently, there have been constant news about ultra-high-voltage tenders. On June 17th, State Grid Corporation of China announced the 33rd batch of procurements in 2024 (the third equipment tender procurement of ultra-high-voltage projects), mainly involving the Shaanxi-Anhui DC ultra-high-voltage project (Shaanxi ±800 kV sending terminal converter station new construction project + Hezhou ±800 kV receiving terminal converter station project). On June 14th, State Grid Corporation of China released the third service (preliminary) procurement of ultra-high-voltage projects, including YW UHV AC, Gansu Badan Jilin Power Sichuan Flexible DC, Jidian (Southern Xinjiang) to Sichuan-Chongqing Flexible DC, Datong-Tianjin South AC, Qinghai-Tibet DC second phase, Gansu-Zhejiang Flexible DC and other line service tenders.
Against the background of the construction of a new power system, in order to serve the large-scale wind and photovoltaic power bases in deserts, Gobi and deserts, and to support and promote the intensive development and long-distance transmission of large-scale power supply bases, the construction of ultra-high voltage is expected to continue. According to Galaxy Securities research report, the investment peak of ultra-high voltage in the past generally lasted for about two years, but this peak is estimated to last for more than five years optimistically. It is expected that there will be about 27-32 new DC transmission channels for external transmission during the "14th Five-Year Plan" and the "15th Five-Year Plan", with a stock of 4 lines, 5 under construction, and a gap of 18-23. At present, 23 DC transmission lines are being promoted (including research, feasibility study, approval, construction, etc.). The 6 ultra-high voltage lines for service tendering in this round are still renewing and promoting expected lines in the preliminary stage. There is still hope for new ultra-high voltage line planning in the later period, and the total scale is expected to exceed expectations, effectively supporting the high prosperity of the construction of ultra-high voltage during the "15th Five-Year Plan".
