库布齐基地特高压外送通道启动建设推动沙戈荒治理与新能源开发

Core Insights - The construction of the Kubuqi Base ultra-high voltage transmission channel officially commenced on September 29, marking the full implementation phase of the largest sand and desert wind and solar power base in China's 14th Five-Year Plan [1][3] - Once completed, the Kubuqi Base is expected to deliver approximately 36 billion kilowatt-hours of electricity annually to the Beijing-Tianjin-Hebei region, with 60% of this energy coming from clean sources [1][3] Project Details - The transmission channel utilizes ±800 kV ultra-high voltage direct current technology, starting from Dalad Banner in Ordos, Inner Mongolia, passing through Shanxi Province, and ending in Cangzhou, Hebei Province, covering a total length of 699 kilometers [3] - The Kubuqi Base project plans to construct 8 million kilowatts of solar power and 4 million kilowatts of wind power, along with 4 million kilowatts of supporting coal power and 5 million kilowatt-hours of new energy storage facilities [3] Environmental and Ecological Impact - The project adheres to the principle of "ecology first, sand control as the main focus," employing a comprehensive management model of "power generation on panels, restoration below panels, and planting between panels" [3] - A three-tier protective system has been established, including high vertical sand barriers, grass grids, and ecological restoration beneath solar panels, creating a three-dimensional ecological barrier that achieves dual benefits of power generation and sand control [3] - To date, approximately 300,000 acres of desertified land have been treated, with expectations to exceed 1.5 million acres by the end of the 15th Five-Year Plan, resulting in an estimated annual electricity generation of nearly 140 billion kilowatt-hours, saving about 42 million tons of standard coal and reducing carbon dioxide emissions by approximately 100 million tons [3]
