Power industry growth and deregulation are causing fundamental changes in the economics of power production and distribution. In order to remain competitive, power producers now seek to improve plant economics through cogeneration, the simultaneous generation of power and production of steam for process use. The majority of manufacturing processes are of a continuous type that require high flexibility for power and steam systems (i.e., require various flows and conditions of steam at various power production levels).

This paper focuses on several ranges of process steam flows and conditions in order to provide a basis for comparison of the most common cycle configurations in combined cycle applications. A non-reheat, advanced technology gas turbine combined cycle facility will be used as the reference plant. Plant design, cycle performance, and economics of each configuration will be evaluated based on requirements of flexibility and process steam flows. This paper will provide guidelines for selection of cycle configurations for cogeneration power plants that will maximize Return on Equity for the owner.
