1989 Illinois Coal Facts PDF Download

Excerpt from The Demand for Energy in the Illinois Coal Market: May 1989 Historically, utilities have utilized high sulfur coal because of its heating value, 'delivered price and localized availability. In return for a guaranteed quantity and quality of coal from coal producers, utilities were willing to sign long-term contracts. Generally, this time period was for the useful life of the coal-fired generating station since a boiler was designed to burn a certain quality of coal and any variation in coal quality could reduce its economic and operational performance. Since the early 1970's, utilities have been required to meet more strict air quality standards. These standards forced utilities to either install expensive environmental control technologies to remove a portion of the pollutant, or burn a coal that had a lower sulfur content. The availability of these compliance coals is primarily limited to the central Appalachian area; Wyoming; Montana; Colorado; and Utah. Most utilities chose to use a compliance coal to meet these stricter environmental standards. However, with the o.s. Environmental Protection Agency's Revised New Source Performance Standard of 1979, utilities have to install control technologies no matter the sulfur content of the coal.
