Abstract

En este artículo se analiza el comportamiento de los grupos de generación eléctrica que toman decisiones sobre inversión y producción en un escenario de mercado liberalizado introduciendo contratos de largo plazo, en un contexto donde hay alto nivel de concentración de mercado. Para ello, se emplea un modelo determinístico dinámico de competencia imperfecta (con estrategias open loop) que se resuelve utilizando un sistema de ecuaciones complementarias mediante el software GAMS, a fin de proveer simulaciones que muestren los impactos de las diferentes estructuras de mercado (monopolio, oligopolio con franja competitiva, oligopolio (Cournot) y competencia perfecta) sobre las decisiones de inversión y producción, asumiendo la existencia de dos bloques horarios (base y pico) y considerando la existencia de dos tecnologías a utilizarse para el despacho eléctrico (hidráulica y térmica) con datos del año base 2011 para un horizonte temporal de 10 años. Los resultados muestran que a pesar de que en los diferentes escenarios de análisis puedan existir indicios de poder de mercado, existe un efecto positivo importante sobre la inversión en capacidad, la producción por tecnología, y precios por bloque de horario. || We analyze the behavior of electricity generation groups that make investment and production decisions in a liberalized market scenario by introducing long-term contracts, in a context where there is a high level of market concentration. In this way, a dynamic deterministic model of imperfect competition (with open loop strategies) is used, which is solved using a system of complementary equations through GAMS software, in order to provide simulations that show the impacts of the different market structures (monopoly, oligopoly with competitive fringe, oligopoly (Cournot) and perfect competition) on the decisions of investment and production, assuming the existence of two segment loads (base and peak) and considering the existence of two technologies to be used for the electric power dispatch (hydraulic and thermal) with 2011 data for 10-year planning horizon. The results show us that although there may be indications of market power in the different analysis scenarios, there is a significant positive effect on investment in capacity, production by technology, and prices per segment loads.
