Description
Summary:The Clean Air Act has assumed the central role in US climate policy, directing the development of regulations governing greenhouse gas emissions from existing coal-fired power plants. This paper uses a model of power plant operation and efficiency investments to compare the cost-effectiveness of alternative policies to reduce greenhouse gas emissions from coal plants. We empirically estimate the key model parameters from a data set of the operation of coal-fired generating units over 25 years. We find that a 10% increase in coal prices causes a 0.1%–0.4% improvement in efficiency (electricity production per ton of coal), which is broadly consistent with engineering assessments of the cost of improving efficiency. We also find that coal prices have a significant effect on utilization. Using the estimates to compare alternative policies, we find performance standards are less efficient than a tax because they cause greater utilization.
