This report describes the development of a database and geographic information systems (GIS) analysis of a defined population of coal-fired power plants in the U.S. to model the cost and assist in the assessment of the feasibility of retrofitting these plants with CO2 capture technology. In addition, an assessment of the impacts on generation, CO2 emission, and fuel consumption should all units be brought up to the average efficiency of the top decile of efficient units by nameplate was made. This report covers data sources, methodology employed, modeling and results. An appendix containing a catalog of aerial imagery used for this analysis is available as a separate document.
