An Oligopolistic, Electricity Generation Expansion Model Which Incorporates Carbon Emissions Trading and Green Certificates

Dr. Pedro Linares

We present a generation expansion model for the power sector which incorporates several features that make it very interesting for its application to current electricity markets: it considers the possible oligopolistic behavior of firms, and incorporates relevant policy instruments such as carbon emissions trading and tradeable green certificates. It combines powerful traditional tools related to the detailed system operation with techniques for modeling the economic market equilibrium and a formulation for the resolution of the emissions permit and tradeable green certificates market equilibriums. The model is formulated as a Linear Complementarity Problem (LCP) which allows to solve simultaneously the optimization problem for each firm considering the power, carbon and green certificate markets. The model has been implemented in GAMS. An application to the Spanish power system is also presented.
