Abstract
Se ha estudiado la posibilidad de aprovechar el recurso hídrico del Rio Claro para la generación de energía eléctrica, ya que, a pesar de que este cauce posee caudales medios mensuales superiores a 8 [m3/s] durante gran parte del año, no cuenta con centrales de generación de energía eléctrica. Durante la recopilación de información fluviométrica surge por parte de la Junta de Vigilancia de la primera sección del Río Claro de Rengo, el antecedente no menor de la existencia de derechos de agua no consuntivos sobre un tramo de este cauce que no están siendo utilizados.
Ante esta situación se ha recopilado información hidrológica de los últimos 30 años del Río Claro, aprovechando la cercanía entre el lugar donde se poseen derechos no consuntivos y la estación fluviométrica Hacienda Las Nieves, para posteriormente medir pendiente y estudiar la mejor ubicación para la central hidroeléctrica de pasada, con la finalidad de seleccionar la turbina apropiada.
Este análisis se plantea que con 1,72 [m] de altura neta y con un caudal de 2,8 m3/s, una turbina de vórtice gravitacional tendría una potencia instalada de 30 [kW], con un factor de planta de 48% y una energía media anual de 125,89 [MWh]. Ante este potencial se realiza un estudio técnico económico, a partir de dos modalidades de negocio, uno amparado en el marco de Pequeño Medio de Generación Distribuida y otro bajo NETBILLING, analizándolas con un horizonte de 20 años, siendo la segunda alternativa la recomendada, ya que, este tipo de central es capaz de generar ahorros en el pago por energía consumida por sobre los $13.154.707 anuales, con una inversión de $6.125.934 por kilo Watt de potencia instalada, y un periodo de recuperación de la inversión de 12,35 años.
Has been studied the possibility to use the Río Claro's hydraulic resources to generate electrical energy, cause/as, this river has average monthly flows greater than 8 [m3/s] during a large part of the year, and doesn't have any electrical power generation plant. During the recopilation fluviometric information process, emergered from “Junta de Vigilancia del Río Claro de Rengo” about existence of non-consumptive water rights in a stretch of the river and they aren't been used. In this situation, has been collected hidrologic Rio Claro's information of last 30 years, profiting the proximity between the place where JVRCR has non-consumptive water rights and the fluviometric station Hacienda Las Nieves, for later to measure the slope and study the best ubication for the hydroelectric power plant, with the purpose to select the apropiate turbine. this analysis proposes that with net head of 1,72 [m] and 2,8 [m3/s], a gravitational vortex turbine would have 30 [kW] of power installed, plant factor of 48% and average annual energy of 125,89 [MWh]. In this scenario, an economic technical study is carried out, from two business modalities, one covered by Small Means of Distributed Generation (Pequeño Medio de Generación Distribuida, PMGD) and another under netbilling, analyzing them with a horizon of 20 years, recommending the second alternative, because, this kind of plant is able to generate annual savings in energy consumed up to $13.154.707, with a invertion of $6.125.934 for kilowatt of power installed, and payback of 12,35 years.
