Precio de las emisiones de CO2 en la generación eléctrica

Abstract

This paper aims to identify the effects of including the price of CO2 emissions in the Total Levelized Cost of Generation (CTNG, in Spanish) of the combined cycle power plant. Monte Carlo simulation is used to estimate the probability densities of the CTNG and the Total Levelized Cost of Generation with Externalities (CTNGE). The effects of the price of CO2 emissions in the CTNG of the combined cycle plant are analysed through the concepts of stochastic dominance. We find that the price of CO2 emissions makes the CTNGE of the combined cycle plant to be higher and riskier than the CTNG. On the other hand, the CTNGE of the combined cycle plant is very sensitive to changes in the price of CO2 emissions. The analysis suggests that the share of electricity generation through combined cycle plants should be reduced to replace it with clean technologies. A limitation of the work is that the CTNG and CTNGE probability densities, generated through Monte Carlo simulation, depend on the data used, so they are sensitive to changes in the input parameters
