Abstract

El propósito de este trabajo es analizar la viabilidad de la utilización del índice de oferta residual (IOR) en el mercado eléctrico mayorista en Colombia, con el fin de promover la competencia. Esto se hace a partir de la revisión de la literatura relacionada con las experiencias internacionales respecto a los mecanismos para monitorear el poder de mercado y del análisis del Documento 118 de la Comisión de Regulación de Energía y Gas (CREG, 2010). La principal conclusión es que el IOR no es un buen mecanismo de control en mercados hidráulicos, mientras que el desarrollo de los mercados de largo plazo ha sido utilizado con gran éxito para mitigar el riesgo de abuso de poder de mercado, según lo muestra la experiencia internacional. ***** This paper investigates the viability of using the Residual Supply Index (RSI) to promote market competition in the Colombian electrical pool. The evaluation is based on a literature review of international experiences of power market monitoring mechanisms and an analysis of CREG Document No. 118 produced by the Colombian Commission for the Regulation of Energy and Gas (CREG). The principal conclusions of the review are that the RSI is not a good control mechanism in hydric markets, and that international evidence shows that the development of long-run markets has been used very successfully to mitigate the risk of market power abuse. ***** Le propos de cette étude est d’analyser la viabilité de l’utilisation de l’indice d’offre résiduelle [IOR] sur le marché de gros de l’électricité en Colombie afin de determiner le degré de concurrence et d’en favoriser son expansion. L’étude part d’une révision de la littérature concernant les expériences internationales de mécanismes de surveillance de la force de marché et sur une analyse du Document 118 de la Commission de régulation de l’électricité et du gaz [CREG, 2010]. La principale conclusion est que l’IOR n’est pas un bon mécanisme de controle des marchés hydrauliques, alors que le développement des marchés a long terme a été utilisé avec succes pour atténuer les risques d’abus de pouvoir de marché, comme le montrent diverses expériences internationales.
