In recent years there has been growing discussion regarding market designs of emissions trading. This paper examines a model in which emissions trading is introduced in the oligopolistic electricity market, which comprises both forward contracts and spot transactions. In particular we investigate how emissions trading is affected by strategic behaviour in an endogenous framework of forward and spot markets. The problem is defined as an equilibrium problem with equilibrium constraints (EPEC). Simple numerical examples illustrate how strategic behaviour could affect equilibrium outcomes and what effects initial allocations of emissions rights could have on social surplus.
