ABSTRACT
The main aspect related to the planning and design of hydropower schemes besides purely technical and socio-environmental issues is the economic evaluation. In case a project or several candidate projects are technically feasible the decision as to which project will be implemented first will be based on key economic parameters, e.g. the specific generation costs or the net benefits of a project. In order to maximize the benefits of a project, optimization procedures have to be incorporated into the planning process. This paper presents some of the optimisation procedures performed during the feasibility study of the Chemoga-Yeda-Sens Hydropower Scheme in Ethiopia, a scheme consisting of three interconnected reservoirs.
