Investment Rating - The report maintains an "Overweight" rating for the construction and engineering sector and a "Buy" rating for non-metallic building materials [1][11]. Core Insights - The Yajiang Hydropower Station has officially commenced construction with a total investment of approximately 1.2 trillion yuan, differing structurally from the Three Gorges Dam [3]. - The Yarlung Tsangpo River downstream hydropower project in Tibet will implement a run-of-river development approach, constructing five tiered power stations to enhance power generation efficiency through cascading water flow [3]. - The average cost of newly approved hydropower projects in 2023 is estimated at 20,344 yuan per kW, suggesting an expected installed capacity of 60 million kW for the Yarlung Tsangpo project [3]. Summary by Sections Project Overview - The Yajiang Hydropower Station project is expected to catalyze future developments, with the next phases likely involving "bidding" and "performance release" [4]. - The project structure is anticipated to differ significantly from traditional reservoir dams, such as the Three Gorges Dam [4]. Comparative Analysis - The Zangmu Hydropower Station, the first large-scale hydropower station on the Yarlung Tsangpo River, has a total installed capacity of 510,000 kW and a total investment of 9.6 billion yuan, with a construction period of nearly eight years [5]. - The Dadu River Hard Beam Package Hydropower Station, with an installed capacity of 1.116 million kW, showcases advanced construction techniques that may parallel those of the Yajiang project [6]. Supplier Insights - The report identifies potential suppliers for the Yajiang project based on bidding data from the Zangmu Hydropower Station, highlighting companies such as China Power Construction, China Energy Engineering, and Huaxin Cement as key players [7]. - The report notes significant stock price increases for several suppliers since July 21, with China Power Construction and Huaxin Cement both seeing a rise of 33% [7]. Investment Recommendations - The commencement of the Yajiang Hydropower Station is expected to generate new demand for construction and materials, prompting a focus on companies involved in hydropower engineering and infrastructure, such as China Power Construction and China Railway [8]. - Material suppliers like Huaxin Cement and equipment providers such as Tianqiao Hoisting are also recommended for investment consideration [8].
