Clean Air Markets - Power Sector Modeling

This area provides information and documentation on EPA’s power sector modeling resources and power sector modeling regulatory applications. In the last few years, EPA has engaged with state air quality planning officials, power company representatives, regional transmission organizations, federal and research organizations and others working on power sector modeling who have provided input on the data, assumptions, and structure of EPA's power sector analytical tools.

EPA uses the Integrated Planning Model (IPM) to analyze the projected impact of environmental policies on the electric power sector.  In addition to IPM, EPA uses additional complementary analytical tools and approaches informing power sector projections and regulatory actions.
