In this work, we study an alternative approach for capping and pricing carbon emissions in electric markets: the cap-and-trade paradigm with re-trade of allowances. We model the electric market (generators and allowances’ auctioneer) as a two stage stochastic capacity expansion equilibrium problem, where we allow future investment and re-trading of emission permits among generators. The model studies generation and future investments in the electric sector in two regimes of demand: deterministic and stochastic. The configuration enforces the reduction of carbon emissions by setting a carbon budget, which allows to assess the impact of green policies and pledges concerning an electric system. We use the proposed model to analyze the Chilean electric sector under a cap-and-trade paradigm as an alternative to the existing carbon tax. We show that the Chilean pledge regarding emissions reductions does …
