DEUS computer evaluation model. Volume 1. Program descriptive manual. Final report
Recent changes in tax laws and fuel uses have provided new incentives for installing cogeneration systems. Prior studies primarily consider the effects on industry. EPRI, therefore, sponsored the DEUS (Dual Energy Use Systems) Analysis of Cogeneration Systems to evaluate industrial cogeneration from the utility perspective and to determine the extent to which potential benefits would accure to a utility in representative site-specific industrial applications. The objectives of this project are to develop a methodology and translate it into a computer program to analyze cogeneration systems from a utility perspective. A computer program was developed that compares a cogeneration system to a no-cogeneration system in an industry with specified heat and power requirements. The economic comparison is based on user-specified utility rate data, including industrial rates and rates for purchases of electricity from cogenerators under Section 210 of the Public Utility Regulatory Policies Act (PURPA). The industrial heat and power requirements and the utility rate data can be specified in a time varying profile for up to 36 periods in a year. The program has the capability to evaluate systems using up to four fuel streams for two sizing options - one matches the maximum thermal load, the other matches both the maximum thermal load and a specified power output. Based on system capital and operating costs, the economics are determined for industrial, utility, and third-party ownership. For industrial ownership the industry can either sell all net power generated and buy back all needed site power. For use as a screening tool, a data base of performance and cost for a nocogeneration and several cogeneration systems is built into the program. System part load performance and applicable fuel characteristics are included. For application studies, the user must determine and specify the performance and cost characteristics for particular systems.
