2025 Reference Case

EPA's Power Sector Modeling Platform Using IPM

February 20, 2026 - EPA is making the latest power sector modeling platform available, including the associated input data and modeling assumptions, outputs, and documentation. For questions or other inquiries regarding EPA’s Power Sector Modeling Platform 2025, please contact us using our online form.

This updated modeling reflects recent updates to federal legislation affecting the power sector, including the One Big Beautiful Bill Act (OBBBA) of 2025, and also accounts for large projected increases in electricity demand stemming from data centers and Artificial Intelligence applications  Fleet information is available in  NEEDS for EPA 2025 Reference Case: rev: 11-28-2025 (xlsx) (5.64 MB)

The Integrated Planning Model (IPM) is a multi-regional, dynamic, deterministic linear programming model of the U.S. electric power sector. It provides projections of least-cost capacity expansion, electricity dispatch, and emission control strategies for meeting energy demand and environmental, transmission, dispatch, and reliability constraints.
