The Debao DC Transmission Project, with a capacity of ±500 kV, serves as a crucial conduit for power transmission from Northwest China. It stands out as the first localized innovation project in China to achieve long-distance and high-power DC transmission through independent design, manufacturing, construction, commissioning and operation.

As the starting point of the Debao DC Power Transmission Project, the ±500 kV Baoji Converter Station plays a crucial role in transmitting thermal and wind power from Northwest China to Sichuan during dry seasons, as well as conveying clean energy power from Sichuan to Shaanxi during wet seasons. This significantly enhances the capacity to optimize resource allocation among regions and realizes electricity complementarity between northwest and southwest power grids, resulting in substantial economic and social benefits while playing a crucial role in achieving "double carbon" goals.

This year's annual overhaul, scheduled from May 20 to 29, 2023, will encompass 17 aspects. The upgrade is expected to further elevate the safe operation level of the Debao DC transition system and enhance the power supply reliability of the Shaanxi Power Grid. These improvements can effectively support the peak summer power supply demands of the Southwest Power Grid while accelerating new energy consumption and injecting new growth drivers into Shaanxi's economic development.
