Estudio de factibilidad para la repotenciación de la Mini Central Hidroeléctrica de 2MW de la Empresa UCEM – CEM, Planta Chimborazo

Abstract

This research was conducted in the UCEM-CEM central mini hydroelectric, located in the Parroquia San Juan, to determine the feasibility of repowering and optimization of power generation. The historical and current state of the consumption and generation of energy of the company was proceeded to analyze with yields of installed equipment. The equipment and infrastructure were observed and the state of operation and functionality of the machines and infrastructure were evaluated. An alternative of investment was proposed with the flow of the equipment found, the same that is used to perform technical analysis of two cases: with an average power of operation of 880 Kw at a stable flow rate of 330 lt/ s with a power of 1258.4 Kilowatt( Kw )and 352 Kilowatt ( Kw), with a differentiated flow rate of 472 lt /s and 132 lt / s, for schedules from 06:00 to 22:00 and 22:00 to 6:00 respectively. The Agency of Control and electricity regulation established the prices in differentiated hours Medium Voltage. The technical, socio-economic, financial and environmental feasibility were assessed. The obtained results say the repowering project is technically feasible with a projected production of 7688.03 Megawatt Hours (Mwh), while the economic evaluation has an Internal Rate of Return (IRR) of 16.28% with financing, and 24.16% without funding in the case of average power and stable flow. The research paper recommends to the company performs the investment in this case, if possible with own financing.
