On September 16 local time, the construction of the Pursat Hydropower Station project in Cambodia undertaken by PowerChina reached an important milestone: the dam filling reached the crest elevation, marking the substantial completion of the main civil works of the dam and providing an important guarantee for the next stage of impoundment through the dam's gates.

The Pursat Hydropower Station is located in Pursat Province in western Cambodia, with a total installed capacity of 80 MW. It is the first cascade and leading hydropower station in the overall planning of the Pursat River Basin, and is a comprehensive water conservancy project with functions including power generation, flood control, and irrigation. The main structures of the headworks project mainly consist of a concrete face rockfill dam, upstream and downstream cofferdams, a diversion tunnel on the left bank, a spillway on the right bank, and a power intake on the right bank. The crest elevation of the concrete face rockfill dam is 184 m, the maximum design dam height is 97.5 m, and the plinth foundation elevation is 80.5 m. The upstream dam slope is 1:1.405, the downstream dam slope is 1:1.4, the crest width is 8 m, the maximum width at the dam base is 290 m, and the crest length is 644.5 m.

Since the dam construction began in early 2023, the PowerChina project team has overcome many challenges such as complex geological conditions, high construction difficulty, and a long rainy season. By optimizing the construction plan, rationally allocating resources, and strictly implementing standardized and refined management, the team has made every effort to ensure the safety, quality, and progress of the project construction, ensuring that the project was smoothly filled to the crest elevation according to the established schedule, demonstrating PowerChina's efficient construction capability and excellent management level in the field of hydropower construction.

Next, the project team will continue to maintain high morale, proceed steadily, and orderly advance the construction of key processes such as face slab concrete pouring, waterstop system installation, embedded metal structures, and flood discharge facilities, so as to ensure high-quality and efficient completion of the project, strive for the early commissioning of the hydropower station and the realization of its benefits, and provide clean and reliable energy security for Cambodia's economic and social development.
