On September 22, 2022, the third UHV project in Jiangxi, the Wuhan-Nanchang UHV AC power transmission and transformation project, officially started construction in Nanyi Town, Ruichang City, Jiangxi Province.

According to reports, the Wuhan-Nanchang UHV AC power transmission and transformation project line is set up with double circuits, with a total length of 456.6 kilometers and 965 new towers, with an estimated total investment of 8.29 billion yuan. The line in Jiangxi Province is 2×251 kilometers long, with 529 new towers and an investment of 4.38 billion yuan, passing through 2 cities and 7 counties (districts).

The Wuhan-Nanchang UHV AC power transmission and transformation project is planned to be fully connected by the end of 2023. After the completion of the project, the "Sun"-shaped UHV main grid will be formed in Central China to support the access and consumption of large-scale green and clean energy, and provide more reliable power support for Jiangxi and even Central China.

The UHV power grid has played an important role in the Jiangxi power grid to ensure power supply in winter and summer and achieve the dual carbon goal. It is understood that as of September 20, 2022, the first UHV project in Jiangxi, the Yahu UHV project, has delivered a total of 24.99 billion kWh of clean energy from Sichuan. On December 26, 2021, the second UHV project put into operation in Jiangxi, the Nanchang-Changsha Saudi high-voltage AC transmission and transformation project, realized the interconnection of the power grids of Jiangxi and Hunan provinces.
