Abstract

Description

A Cogeneration analysis computer program called CELCAP was obtained from the Navy's Civil Engineering Laboratory. Hourly steam loads as well as hourly electrical loads were required to optimize the Cogeneration system. Other information required by CELCAP was the cost of natural gas, e l e c t r i c i t y , and operating and maintenance cost of the boilers. : CELCAP was run without a Cogeneration system to determine the base case c o s t s . Various types and sizes of Cogeneration systems were then run by CELCAP to determine the optimum system. Both simple payback and net present value (NPV) economic analyses were made. . Most of the input information required for the analysis was obtained from the CC Physical Plant personnel. Hourly steam and e l e c t r i c i t y loads (demands) were acquired for one working day and one nonworking day for each month. CC is currently paying $5.20 /MCF for natural gas and an average of 6.50<t/kwh for electricity.
