One of the first implications of full competition in the utility industry is the reluctance to risk capital intensive investments in new plant construction. As the Department of Energy`s Clean Coal Technology program readies a suite of technologies for commercial application, and as deregulation unfolds, the electric utility industry begins to look at the potential for repowering existing sites. This approach to power plant investment involves applications of repowering technologies, upratings, and refurbishing older stations. The decision to repower is influenced by factors that include market demand, power station characteristics, and technology choices. This paper describes the results of a comparative technical and economic evaluation of several clean coal technologies in a repowering application. The objectives of the study were to compare thermal and economic performance of a suite of clean coal technologies in a repowering application under a consistent set of guidelines. Approach The approach taken in this comparative evaluation of Advanced Technologies in a repowering application was to define a reference pulverized coal (PC) fired power station, and then apply each candidate technology in succession. Each case was modeled in a modified version of the ASPEN/SP flow sheet simulation program, along with a suitable combustion turbine, where applicable, and the host plant steam cycle. Pittsburgh No. 8 coal is used for most of the cases evaluated, except for one case involving a natural gas fired combustion turbine, another case where the technology variable is the use of a Process Derived Fuel ( ENCOAL Corp. PDF) in place of coal, and a third case where coal is the primary fuel, but some natural gas is used for topping combustion.
