Propuesta de una metodología de cálculo del costo variable de producción de centrales hidroeléctricas: detalle de costos variables relacionados con la producción de energía eléctrica.

Abstract

In this document, is developed a methodology for the compute of variable costs of production in hydro power plant of large size in Ecuador, the same that will allow the improving of economic dispatch and commercial liquidation in Ecuadorian market. The methodology presented offers the possibility of obtaining major variable costs of production and nearby to the expected in a hydro power plant, of those currently are in use, in comparison with the values that are currently handled that are determined by the report of the proposed change to regulation Nro. ARCERNNR -004/2020. The develop of this methodology is based on the separation of hydropower´s total variable production cost into different components, same that have been adjusted to Ecuador case, being able to provide a mathematical formulation or failing that a range of values that allow weighing its appropriate numerical value for each type of hydro power plant. The compute of each component and its additional values will bring the total amount of variable costs of production in hydro power plants that it is expected to be adopted and/or adapted for each case, thus allowing a better economic dispatch at national level.
