These procedures aim to collect all the geological, geotechnical, topographic, and bathymetric data essential for the materialization of the Detailed Preliminary Project. Assessing soil resistance, evaluating the seismicity of targeted sites, and modeling the hydraulic behavior of the future reservoir constitute the technical prerequisites required of future contractors before engaging any construction phase.


The overall project configuration, outlined at the conclusion of the feasibility studies entrusted to the consortium led by ISL Engineering, envisages a combined capacity of approximately 399 megawatts. This hybrid architecture associates an upstream hydroelectric unit of 54 MW, a downstream hydraulic plant of 234 MW, and a solar park with a capacity of 111 MW. Geotechnical investigations budgeted at 1.15 billion FCFA over eight months must notably guide the choice of materials and concrete composition, while the topographic component, valued at 300 million FCFA, will enable the precise establishment of the reservoir’s volume curves.


Parallel to physical engineering expertise, a detailed environmental and social assessment was launched at the end of July 2026 to measure the cumulative impact of the future works on local ecosystems and riverside populations. While the World Bank’s support positions this site among national energy development priorities, current procedures are limited exclusively to the preliminary studies phase. No civil works execution schedule nor definitive financial package has yet been finalized for this large-scale project, which clearly distinguishes itself from the small existing structure already in service at Mbakaou-Carrière.
