    Desde principios de los años 90 se ha producido una ola de liberalizaciones de los mercados eléctricos bajo la premisa de que la presión competitiva llevaría a una reducción en el coste de suministro. No obstante, gran parte de los estudios académicos concluyen que estos mercados están distorsionados por el abuso de poder de mercado. Sin embargo estos estudios se basan en modelos teóricos y herramientas que parten de una representación simplificada de la realidad, sesgando sus resultados y exagerando el riesgo de abuso. Este artículo repasa las limitaciones de algunas de estas herramientas y, como alternativa, sugiere diversos indicadores derivados de la observación del comportamiento que realmente tienen de los generadores, de modo a obtener conclusiones más robustas y fiables sobre su comportamiento. Estos indicadores permiten rechazar la hipótesis de que existe un problema de poder de mercado en el mercado eléctrico español. Since the early 90's there has been a wave of deregulation of electricity markets under the assumption that competitive pressures would lead to a reduction in the cost of supply. In contrast, many of the published studies conclude that these markets are distorted by the abuse of dominant position of incumbents. However, these studies are typically based on theoretical models and tools based on a simplified representation of reality, and by ignoring critical features that constrain the ability or incentives of generators, bias the results and exaggerate the risk of abuse. This article reviews the limitations of some of these tools and, as an alternative, it suggests various indicators of market power abuse derived from the observation of the actual behavior of the generators, so as to obtain more robust and reliable conclusions about their behavior. These indicators reject the hypothesis that generators exercise market power in the Spanish electricity market.
