Group 1: Project Overview - The Yarlung Zangbo River hydropower project has a total investment of 1.2 trillion yuan, with potential additional investments bringing the total to over 2 trillion yuan [3][6]. - The project will consist of five hydropower stations with an installed capacity of 60-70 million kilowatts and an annual power generation of approximately 300 billion kilowatt-hours, which is three times that of the Three Gorges Dam [6][8]. - The project is expected to take 12-15 years to complete and will play a crucial role in China's "West-to-East Power Transmission" strategy [6][16]. Group 2: Key Beneficiaries - The China Three Gorges Corporation will be the largest shareholder of the newly established Yajiang Group, holding 35% of the shares, and is expected to be the primary beneficiary due to its extensive experience in hydropower construction and operation [7][8]. - China Huaneng Group is also positioned to benefit significantly, leveraging its established presence in the region and its extensive hydropower assets [8][9]. Group 3: Engineering and Construction - China Power Construction Corporation and China Energy Engineering Corporation are identified as the main engineering forces for the project, with expertise in large-scale hydropower construction [10][12]. - The project will utilize innovative construction techniques to address challenging geological conditions, including a total tunnel length exceeding 50 kilometers and a maximum depth of 3,000 meters [11][12]. Group 4: Supporting Infrastructure - The project will be complemented by the construction of high-voltage direct current (HVDC) transmission lines, including the recently approved "Southeast Tibet to Guangdong-Hong Kong-Macao Greater Bay Area ±800 kV DC project," which will facilitate the long-distance transmission of electricity [14][15]. - The anticipated investment for the HVDC infrastructure could reach approximately 600 billion yuan, indicating significant future capital requirements for supporting the hydropower project [15][16].
