Feasibility of cogeneration for a single process industry. Energy management memorandum TM-82-5
The economic feasibility of cogeneration for a single small industrial process steam user in Chicago was investigated. Cogeneration options considered included three gas turbines, three dual-fuel diesels, and two fired boilers with steam turbines. Fuels included a locally available medium-BTU gas. For the fired-boiler and steam-turbine pair, low sulfur coal was also analyzed. Finally, the option of a low-sulfur coal fired boiler without cogeneration was analyzed. None of the options considered yielded the minimum acceptable rate of return on investment (ROI) of 18%. The best alternative - medium-BTU gas-fired boiler and steam turbine - yielded only 12.7% ROI, corresponding to a 4.4 year payback period. It is therefore concluded that cogeneration is not warranted for this industry for projected conditions. (LEW)
