Estudio de prefactibilidad de una central hidroeléctrica en el Río Alambi en la zona del poblado de Tandayapa.

Abstract

The present title work aims to evaluate, at a pre-feasibility level, the technical, economic, and constructive feasibility of a Small Hydropower Plant, located in the high basin of the Alambi River in Tandayapa, northwest of Pichincha. This study is part of the project "Hydroelectric Solutions for emerging and developing countries - HYPOSO" with code: PIE-DICA-UE-2019. First, a general review of the area was done by local visits and the compilation of existing information. Thanks to this, there are three different design alternatives conformed by: water intake, desander, conduction, forebay, penstock and powerhouse. The location of the hydraulic structures was determined by geological and topographical studies, while for the hydraulic design a flow rate of 3 m3 /s was determined, this last one considers available water for power generation, environmental conservation, and different uses of water in the area. Once the final design is ready, the reference budget and the energy production are calculated for each alternative, all this to do a financial analysis through IRR or Internal Rate of Return and the Benefit-Cost indicators for a period of 15 years. Finally, the most convenient design alternative is selected by a multi-criteria analysis matrix, which incorporates financial, hydrological, geological, environmental, construction and social aspects.
