en.Wedoany.com Reported - On the morning of June 24 local time, with the successful lowering of the upstream inlet closure gate at the dam's diversion bottom outlet section, Gabon's Kinguélé Aval Hydropower Station officially commenced gate closure and impoundment. Witnessed by local representatives and all participating parties, the project achieved another significant milestone.
The Kinguélé Aval Hydropower Station is a run-of-river hydropower plant with an installed capacity of 34.95 MW. The normal storage level of the reservoir is 61.00 meters, with a dead water level of 58.00 meters. The corresponding storage capacity at the normal storage level is 28.1 million cubic meters, and the regulating storage capacity is 6.6 million cubic meters. The main structures of the project consist of a dam, an uncontrolled spillway with a stilling basin, a water diversion system, a surface powerhouse, and a switchyard.
Since the completion of the concrete gravity dam on May 19, the project team has focused on the gate closure and impoundment target, with all members working in coordination to efficiently advance related tasks such as commissioning of gate hoists, demolition of temporary facilities, collection of safety monitoring data, and environmental remediation of the reservoir area. During this period, the project team held multiple rounds of acceptance review meetings with foreign supervisory engineers, strictly controlling quality and safety, thereby providing strong assurance for the timely achievement of the gate closure and impoundment milestone, marking a critical step toward subsequent unit power generation and project completion and delivery.
The project team will fully accelerate the installation and commissioning progress of electromechanical equipment, striving to meet the power generation target, and continue to promote the China-Africa joint construction of the Belt and Road Initiative. This will accelerate the transformation of local natural resources into "green power" driving socio-economic development, empowering Gabon's economic and social progress with green hydropower.
