Prioritizing small hydropower projects in scenarios with limited financial resources
Because of the maturity of its technology, small scale hydropower generation is one of the main energy sources to be considered to provide electricity to areas far from the national grid. Very often, because of the economic limitations of the communities that can be supplied with electricity, these projects are unappealing from the entrepreneur's point of view; however, they can have such a great positive impact on the life of these communities, with little impact on the environment, that they may well justify subsidies for their construction. This paper describes a mathematical model that combines multicriteria analysis and a knapsack problem formulation for optimizing the distribution of limited financial resources among several options available of hydropower projects with a stochastic behavior in their initial cost. The test data were obtained mainly from 14 prefeasibility studies of sites in rural Nicaragua with potential for small hydropower. Five scenarios are presented, assessing the impact of multicriteria and different subsidy conditions or economic efficiency requirements. The results indicate that the presented method is suitable to be used for an efficient distribution of limited monetary resources for funding small hydropower projects, and, therefore, can be a useful tool in decision making process. The proposed method can be adapted for application to projects based on other forms of renewable energy, and can also be adapted for prioritization of projects based on different energy resources.
