The Shaanbei-Anhui ±800-kilovolt ultra-high voltage direct current (UHVDC) transmission project has been completed and commenced operation on Tuesday, according to the State Grid Corporation of China.
The project marks the nation's first UHVDC transmission project to go into service during the 15th Five-Year Plan (2026-30) period, representing another landmark development in the country's efforts to serve the national "West-to-East Power Transmission" strategy.
The commissioning of the line holds major strategic significance for enhancing national energy security guarantee capabilities, promoting the trans-regional optimal allocation of clean energy, and accelerating the green and low-carbon transition of the energy sector.
With a total investment of 20.50 billion yuan, the transmission line stretches 1,055 kilometers, and features a rated voltage of ±800 kV and a rated capacity of 8 million kilowatts.
Once fully operational, the project will transmit more than 36 billion kilowatt-hours of electricity to Anhui province annually. Notably, new energy power will account for over 50 percent of the total transmitted volume, playing a vital role in balancing mid-to-long-term power supply and demand while upgrading and optimizing the energy structure.
