Coal Capacity at Risk for Retirement in PJM: Potential Impacts of the Finalized EPA Cross State Air Pollution Rule and Proposed National Emissions Standards for Hazardous Air Pollutants.

In its role of maintaining reliability and resource adequacy, PJM has been following the finalized Cross State Air Pollution Rule (CSAPR)1 and proposed National Emissions Standards for Hazardous Air Pollutants (NESHAP),2 issued by the United States Environmental Protection Agency (EPA), affecting electric generating units, and coal-fired units in particular. PJM has been in the process of estimating the impacts of these rules on the amount of coal-fired generating capacity that may retire, rather than install pollution control retrofits by examining the retrofit status of coal capacity by the age and size of coal-fired units.
