Survey of Emissions Models for Distributed Combined Heat and Power

Research Report IE071


Will Gans, Anna Monis Shipley, and R. Neal Elliott


Despite the multitude of benefits, relatively few tools exist for estimating the regional emissions implications of a combined heat and power (CHP) system, or for predicting how CHP will affect constrained transmission systems or distributed emissions implications. Specifically, the impact of a CHP system on regional, utility-generated emissions needs to be quantified and better understood. The models surveyed in this study vary in design, scope, and detail, but they all seek to capture the functions of an energy economy and use knowledge of economic interactions to simulate the effects of economic and policy changes. In this document, Integrated Planning Model (IPM), Average Displaced Emissions Rate (ADER), Market Allocation (MARKAL), All Modular Industry Growth Assessment (AMIGA), Oak Ridge Competitive Electric Dispatch (ORCED), and National Energy Modeling System (NEMS) models are addressed.
