Fifteen municipal electric utilities are jointly studying the feasibility of developing a 500 MW to 1,000 MW coal-fired generation project. The project will combine advanced technologies seeking maximum performance, minimal risk and outstanding environmental acceptability. This paper describes engineering and financial studies comparing coal-firing technology alternatives such as Pulverized Coal (PC), Circulating Fluidized Bed and Integrated Gasifier Combined Cycle, and PC refinements including supercritical steam conditions and innovative use of gas turbine feedwater heating. The paper also examines options to minimize environmental impact. Use of high-efficiency steam plant technologies is found to be an environmental advantage. A prudent combination of sophisticated technologies is found to be cost-effective. Finally, the paper describes the project’s innovative joint development process.
