【 摘 要 】

This report explores the ability of distributed generation (DG) options to provide cost-effective alternatives to central station generation, transmission, and distribution upgrades for alleviating transmission and distribution congestion. The need for this study was driven by three major factors: (1) DOE's DG program, while quite successful in showing the value of DG in large portions of the United States, has been less successful in the Southeast, likely because of the low energy prices, high excess electrical capacity, and lack of electricity deregulation in the region. (2) Lack of DG-related analysis that uses real world data on specific sites that can be used as good indicators of the issues and benefits of DG. (3) Interest on behalf of DOE in analysis in two southern states that can be used to show the value of DG to several key Congressional officials from the states. To demonstrate this ability for constrained sites in systems in the states of Florida and Mississippi, the Electricity Asset Evaluation Model (EAEM) is used to assess the costs and benefits of installing DG options to reduce load in areas with transmission congestion versus upgrading the transmission and distribution (T&D) systems.
