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.
