Core Insights - The article discusses the comprehensive development of the Yarlung Tsangpo River downstream hydropower project, led by China Yajiang Group, with a total investment of 1.2 trillion yuan and a planned capacity of 60 million kilowatts, aiming for an annual power generation of 300 billion kilowatt-hours [1][6]. Upstream Industry - The upstream high-end equipment manufacturing sector exhibits a multi-dimensional competitive landscape, with Dongfang Electric holding a 45% market share in the turbine sector, expected to capture over 40% of the turbine and auxiliary equipment value for the Yajiang project, translating to an order size exceeding 28 billion yuan [3][5]. - In the tunnel boring machine (TBM) sector, China Railway Construction occupies a dominant position with a 50% market share, anticipated to secure orders for 25 hard rock TBMs, accounting for 45%-68% of the total orders, with a median value of 3.675 billion yuan [3][5]. - The peak delivery period for high-end equipment is projected between 2028 and 2035, which will have a long-term stimulating effect on the industry chain [3][5]. Midstream Industry - The design and construction of hydropower projects face significant technical barriers and high industry concentration, with the Yajiang project expected to generate design contracts worth 24 billion yuan, based on a 2% design fee of the total investment [6][9]. - China Power Construction, as a leading player in global hydropower engineering, is expected to undertake over 50% of the main engineering volume for the Yajiang project, leveraging its expertise in complex geological engineering [8][9]. Downstream Industry - The Yajiang Group's electricity transmission primarily relies on "Tibetan electricity transmission," with over 70% of power sent out through ±1100 kV UHVDC technology, which allows for efficient long-distance transmission with losses below 10% [11][12]. - The investment in supporting transmission projects is estimated to exceed 240 billion yuan, contributing to a significant market opportunity in the UHV sector [12][14]. Supporting Services - The ecological restoration aspect of the Yajiang Group's operations focuses on smart monitoring technologies and ecological benefit transformation mechanisms, establishing a comprehensive ecological monitoring network [15][16]. - The fish species enhancement project has successfully bred rare fish species, contributing to biodiversity and receiving international recognition for its ecological restoration model [16][17].
