Environmentally compatible hydroelectricity for small businesses and rural households – Madagascar

Based on a preliminary study from 2013 and a feasibility study carried out by a local hydropower planner and developer called AIDER in 2019, a detailed design study of the project is developed for the Small Hydroelectric Power Plant (PCH) of Mandialaza with a capacity of 2 x 100 kW. The role of Skat is to accompany the different stages of the work and provide the necessary technical support to ensure the quality of the study, with a focus on the hydrology and civil engineering parts as well as hydraulic- engineering structures up to the turbine.

Description of the Project:

Objective: Development of a quality detailed design study for the 200 kW Mandialaza Small Hydroelectric Power Project for the supply of a local mini grid.

Services provided by Skat: technical support in the design process of the detailed engineering for the planned hydroelectric power plant to be implemented under the project.

Activities in particular: validating, commenting and exchanging with the developer and planner AIDER on the following chapters of the study:

  • Hydrological assessment including flow duration curve, design flow and relevant design flood;
  • Geological studies;
  • Civil engineering and hydraulic engineering parts up to the turbine;

In addition, providing opinion to ensure overall consistency of the detailed design.

Results: comments and recommendations contribute to the feasibility and professional completion of the study, minimisation of implementation risks and strengthened capacity of the project planner and developer AIDER.
