The power industry faces many challenges based on increased competition and stringent environmental regulations. Fuel switching options involving coal and natural gas offers economic and environmental benefits when used individually or together. Proper evaluation of the cost impacts involves consideration of the following: seasonal and inflationary effects on fuel prices (coal and gas), alternative gas firing technologies and plant operating philosophy. This paper describes the development of a State of the Art Power Plant (SOAPP) software Module for evaluating gas fired technology options on coal fired units using a personal computer. The Module provides technological process information, computes boiler and plant performance, develops capital and O and M cost estimates and provides overall economics on the various types of coal and natural gas firing technologies. The inputs to the Module include the turbine, boiler, emission control and major balance of plant equipment. Default values are provided for all inputs. The results, displayed in terms of load, coal-to-gas ratios and time duration are sufficiently detailed for conceptual design, performance and overall economic evaluations. Gas Research Institute (GRI) has sponsored the Module development Electric Power Research Institute (EPRI) provided support for the project and Sargent and Lundy is the developer of the Module.
