Comportamiento estratégico de las plantas generadoras en la bolsa de energía colombiana : pronósticos climatológicos y mantenimientos

The Colombian electricity sector is structured to promote efficient prices in a free competition environment through an energy spot market called "Bolsa de Energia" (BE). Negotiations on BE are made using a mechanism known as multi-unit uniform price auction. This mechanism is designed under the aspiration of a competitive market that reveals the marginal cost. Nevertheless, evidence shows that the energy market operates as an oligopoly with higher prices than those that could be obtained under perfect competition. In addition there are opportunities of higher revenues for the firms if they take strategic behaviors when they include certain events in their profit maximization process. Those situations are the arrival of new forecasts for weather variables, and the planning and maintenance schedules of the largest generation plants in the market. This paper studies empirically the relationship between changes in the auction firms? offers and both events Based on BE data from 2000 to 2014, the results shows that firms change their offers with changes in El Niño weather phenomenon forecasts and with maintenance procedures for the largest plants in the market. Also, we find heterogeneous reactions from hydroelectric plants with respect to thermoelectric ones. Findings are analyzed in a framework of a theoretical model for multi-unit uniform price auctions (Hortaðcsu & Puller, 2008).
