    (Universidad EAFIT, 2016-07-01) García, John J.; Moncada, Jhonny; jgarcia@eafit.edu.co; jmoncad7@eafit.edu.co
    The price bid mechanism in the Colombian electricity market exhibits a strategic behavior, inherent in their oligopolistic market structure, not only for its high hydrological percentage, about 80%, but also because the power plants geographical location, near to the Andean Region. This research designs a spatial weights matrix reflecting characteristics the power plants geographical location, who is incorporated into a spatial Durbin panel to identify the economic geography behaviors, in addition to the fundamentals that explain the prices formation in this market.

    Precios y desempeño regulatorio en el pool eléctrico español
    (Universidad EAFIT, 2015-07-15) García, John J.; Moncada, Jhonny; jgarcia@eafit.edu.co; jmoncad7@eafit.edu.co
    This study examines the relation between the gap of the system marginal price and other common variables in the market such as industrial organization and regulatory changes in the Spanish electricity pool. We estimate a long panel model where the time is larger than the number of firms. Our findings show that high market concentration and the possibility of being a pivot agent generate adverse effects on price determination. In addition, regulatory changes did not generate the expected effects, creating distortion and incorrect incentives in the market.

    Veinte años de funcionamiento del Mercado Eléctrico Mayorista en Colombia: algunas reflexiones
    (Universidad EAFIT, 2015-09-04) García, John J.; López Álvarez, Gustavo; Marín, Fredy; Moncada, Jhonny; jgarcia@eafit.edu.co; glopezal@eafit.edu.co; fmarinsa@eafit.edu.co; jmoncad7@eafit.edu.co
    The aim of this paper is to analyze wholesale electricity market performance in the twenty years of existence. After describing spot market operation, the market for long-term and reliability charge, we analyzed the effect of variables such as El Niño, the reservoir level, the ratio of the actual availability and market demand and some effects of regulatory changes on the spot price. Also through a stochastic model we set up some recommendations on how to improve the functioning of this market with standardized contracts implementation considering international experience. Despite the market's advance in these twenty years of operation, there are still issues to be resolved, such as contracts standardized long-term implementation, smart grids and lowering the threshold to enter the unregulated market, as these aspects would help to reduce the spot price.
