Abstract

This paper considers the effect of electricity generation reliability on the spot price of the electricity market in Colombia, a mechanism implemented in 2006 to encourage existing generators or new investors to increase the installed capacity in the wholesale energy market. We describe the performance of this mechanism in Colombia and analyze the behavior of some structural variables in the operation of this market, such as the ratio between the market demand and the actual availability, El Nino and La Nina, the reservoir level and some regulation measures. The spot price presents high volatility implying that the proper specification corresponds to a regression model with ARCH structure (Engle, 1982). Results show that the reliability charge is positive and statistically significant. Also El Nino has a positive impact on the spot price, due to the large hydraulic share of this market. ****** Este paper considera el efecto del cargo por confiabilidad sobre el precio spot de la energía eléctrica en Colombia, implementado en 2006 con el fin de incentivar a los generadores existentes o nuevos inversionistas para mejorar la confiabilidad de la prestación del servicio, lo que conduce a incrementar la capacidad instalada en el mercado de energía mayorista. Se describe el funcionamiento de este mecanismo en Colombia y analiza el comportamiento de algunas variables estructurales en el funcionamiento de este mercado, como la relación entre la demanda comercial y la disponibilidad real, el fenómeno de El Nino y La Nina, el nivel de embalse y algunas medidas de carácter regulatorio. El precio spot presenta alta volatilidad haciendo que la especificación adecuada corresponda a un modelo de regresión con estructura ARCH (Engle, 1982). Los resultados obtenidos evidencian que el cargo por confiabilidad es estadísticamente significativo y positivo, es decir hace que el precio spot aumente. Además, El Nino presenta un impacto positivo sobre el precio spot, debido a la gran participación hidráulica de este mercado.
