On August 18, following a joint on-site inspection and data analysis by all participating parties, it was confirmed that the concrete strength of the generator floor of the powerhouse of Cambodian Upper Tatay Hydropower Station, invested in and operated by CHMC, met design standards. This milestone signifies the full completion of the main civil structure of the powerhouse and marks the project’s transition into full-scale electromechanical installation phase, 12 days ahead of schedule. This achievement represents another key milestone in 2025 and lays a solid foundation for the project’s goal of commencing full operation and power generation in 2026.

Located on the left bank of the lower Kep River, the powerhouse of Upper Tatay Hydropower Station adopts a shore-based, surface-type design and houses two Francis-type turbine generator units, each with a capacity of 75 MW. The structure measures 78.8 meters in length, 47.3 meters in width, and 53 meters in height, with a total excavation volume of 301,000 cubic meters and a total concrete volume of 55,310 cubic meters.

At present, the project has entered the peak phase of electromechanical equipment installation. CHMC remains focused on critical tasks such as unit installation, commissioning, system integration, and powerhouse interior finishing, while strictly upholding quality and safety management standards. Every effort is being made to ensure the Station is completed and put into operation on schedule, contributing strong momentum to the development of Cambodia’s clean energy sector.
