The price escalation rates for electricity and fuel estimated in this evaluation process might
not be exact. Similarly, the installation cost represents a large investment and changes in this
cost can affect the results significantly. Sensitivity analysis of IRR of the feasible
cogeneration systems is done assuming changes in each of these factors.
The following two acceptable alternatives are taken as examples for the sensitivity analysis:
(1) Steam Turbine, Thermal Match [STTM]: 5,000 kg/hr, Turbine steam inlet pressure:
40 bar;
(2) Diesel Engine, Power Match [REPM]: 1,500 kW Power Demand.
