Abstract
We examine overlapping regulations in electricity markets. Using an example based on a stylized model of a competitive energy market, we study cost-reduction and cost-padding incentives by “green-energy” producers in an electricity market employing an emissions tax and the simultaneous use of a green quota for the generation portfolio and a fair rate-of-return constraint implemented via a system of feed-in tariffs. We show inter alia that when subsidies are phased out, exploitation of the green technologies full cost-reduction potential is a Nash Equilibrium but emissions will increase. In addition, green-energy producers can engage in collusive cost padding to increase profits even as they satisfy the policymaker's desired green quota.
