Based on the experience of previous feasibility case studies, the potential viability of a number of cogeneration and alternative fuel options in Chicago were assessed. The systems studied were regarded as central energy facilities that could serve a number of industries or institutions in the City. In the limit, a single user could be dealt within the context of the results as well. The eleven options considered included refuse, natural gas and low-sulphur coal fuels as used in various fired boilers, gas turbines and diesels. The range of available outputs analyzed were 42,400 - 616,000 lbm/h or 150-psig steam and 1.2 - 93.2 MW(e). Typical values of economic parameters representative of the City were employed as suggested by the previous case studies. The situation of taxable ownership with 60% IDB (Industrial Development Bond) and 40% leveraged lease financing was used. In addition to providing for adequate costs of debt and lease service, a 15% discount on all cogenerated thermal and electrical energy was built into the venture. Because the users would not be providing equity capital for the proposed scheme this incentive is important in order to assure a significant benefit to candidate industries and institutions. While these and other assumptions may have to be modified in site-specific applications, the results are believed adequate for screening purposes and to indicate whether further study may be warranted or not. The basic economic analysis was a variation of the justifiable capital cost method. In the present case, the costs of equipment exclusive of distribution costs were known for the eleven options. Any balance available could be used for distribution. Estimates of distribution cost per unit length were used to generate maximum allowable distribution distances (if any) for each plant.
