Report – Resource Adequacy Implications of Forthcoming EPA Air Quality Regulations

Resource Adequacy Implications of Forthcoming EPA Air Quality Regulations, December 2011

  • “This report presents the results of an independent assessment by the U.S. Department of Energy (DOE) of the adequacy of U.S. electric generation resources under air pollution regulations being finalized by the U.S. Environmental Protection Agency (EPA). This report does not estimate the economic impacts of EPA regulations, nor does it provide detailed reliability assessments that planning authorities and other stakeholders will need to conduct to ensure deliverability of power and grid reliability during implementation of EPA rules. This report considers two EPA regulations, the Cross-State Air Pollution Rule (CSAPR) and the Mercury and Air Toxics Standards (MATS), that are widely expected to have the greatest impact on the electric sector between now and 2015. CSAPR creates multiple trading systems to control the emissions of NOx and SO2 from electric generators, and MATS imposes emissions rate standards on coal and oil-fired electric generators for mercury, acid gases and particulate matter. The trading systems for CSAPR begin in 2012, with the limits tightening for sources in some states in 2014. The first year of compliance for MATS is 2015, subject to potential extensions discussed in this report.”
