How U.S. EPA projects the impact of air emission policies on the electric power sector

This paper describes how the U.S. Environmental Protection Agency (EPA) uses the integrated planning model (a large linear programming optimization model of the U.S. electric power sector) to project the impact of air emissions policies on the U.S. electric power sector over a 10-25 year time horizon. Specific examples are given of the model's projections for the Clean Air Interstate Rule (CAIR), a regulation that was issued by EPA on March 10, 2005.
