ECT Power Plant Survey

The CAER conducted surveys of Kentucky's coal-fired power plants in 1992, 1997, and 2002 with questionnaries regarding the previous year's statistics. Previously-published data from a 1978 survey was also incorporated. Surveys involve both collection of information from utilities and the collection of coal and ash samples from each power plant. Detailed data on all power plants in the US can be downloaded at http://www.eia.doe.gov/cneaf/electricity/page/eia767.html.
