“雅下”水电正式开工，利好基建链

Investment Rating - The report maintains an "Overweight" rating for the construction and engineering sector and the building materials sector [5]. Core Insights - The "Yaxia" hydropower project, with a total investment of approximately 1.2 trillion yuan, is expected to significantly benefit the infrastructure construction and cement industries due to increased demand for materials [1][3]. - The project is the largest planned hydropower project globally, with an installed capacity of about 60 million kilowatts, which presents substantial opportunities for companies with integrated planning, design, and construction capabilities [2]. - The project is anticipated to create a demand for over 25 million tons of cement and more than 500,000 tons of water-reducing agents and explosives due to its extensive construction requirements [3][4]. Summary by Sections Project Overview - The "Yaxia" hydropower project officially commenced construction on July 19, 2025, in Linzhi, Tibet, and involves the construction of five tiered power stations [1]. - The project is expected to have a construction investment of approximately 705.6 billion yuan, with an average annual investment of about 47 billion yuan over a 15-year construction period [2]. Material Demand - The project is projected to require approximately 79.33 million cubic meters of concrete and 380 million tons of earth and rock excavation, leading to increased demand for cement and related materials [3]. - The local cement production capacity in Tibet is currently limited, with a total daily output of 39,500 tons from nine companies, indicating a high reliance on external supply for the project [3][10]. Innovation and New Materials - The complexity and scale of the project are expected to drive innovation in construction methods and materials, particularly in ground treatment and functional new materials [4]. - The project will benefit from central budget investments, policy bank loans, and long-term special bonds, which are likely to accelerate construction progress [4].
