The transmission of green electricity from the integrated water and landscape base in the southwest region to the load center in the central and eastern regions through the UHVDC channel is an important part of China's “west-to-east transmission” strategy. China is rich in hydraulic resources, with reserves exceeding 6 trillion kilowatt-hours, ranking first in the world. Among them, the southwest region is the richest in water energy resources, accounts for about 70% of the country's developable volume, and has excellent landscape resource conditions. Watersheds such as the Dadu River, Yalong River, Jinsha River, and Lancang River have strong hydropower regulation capabilities, which can complement the variability of scenery to achieve integrated development and utilization of water and landscape. The Shuangjiangkou Power Station, which has recently been put into operation, is the leading power station in the Dadu River Basin. It has annual adjustment capacity. It can store incoming water during the abundant water period to generate electricity during the dry water period, improving the overall regulation capacity of downstream power plants. By the end of September 2026, a total of 12 UHVDC projects had been completed in the southwest region, with a transmission capacity of nearly 85 million kilowatts. He Zhao, deputy director of the General Electric Power Planning and Design Institute, explained, “Transforming the resource advantages of the western region into economic advantages, and at the same time driving the development of upstream and downstream industries in new energy, transmission and transformation equipment manufacturing, driving the industry to invest hundreds of billions of yuan and create hundreds of thousands of jobs. From an environmental perspective, it can effectively replace coal-fired power generation in the central and eastern regions, and is expected to reduce carbon dioxide emissions by about 300 million tons per year. ”
