China opens 2000 km 800 kV DC power line, a west-east strategic artery

According to China’s National Power Grid, the construction of the 2000 km long 800 kV ultra-high-voltage DC power transmission line from Baihetan power plant to Jiangsu was completed and put into operation on January 1. This is a strategic artery of China’s “West-to-East Transmission” project, transmitting 30 billion kWh of green electricity generated in the western region to the eastern region every year.

The project straddles Sichuan, Chongqing, Hubei, Anhui, and Jiangsu provinces. Total investment was 30.7 billion CN„.

The project is calculated to reduce the annual use of coal for power generation in East China by 14 million tons and carbon dioxide emissions by more than 25 million tons.

As of the end of 2021, Sichuan’s hydropower installed capacity was 89.47 million kW, ranking first in the country in terms of both installed hydropower capacity and annual power generation. The Baihetan hydropower plant, located in the main stream section of the Jinsha River, has an installed capacity of 16 million kW, second only to the Three Gorges Power Plant, and is scheduled for completion and full operation in 2022.
