Reply to comments on ‘derivation of an index for evaluating economics of cogeneration systems and its applications’

摘要

AbstractThe Economics of a cogeneration system for district heating and cooling (CGS) depend not only on the exergetic efficiencies of generating heat and power, but also on various other factors such as the capacity factor, the construction cost of the CGS, and the annual cost rate for the construction cost. One of economic difficulties of a CGS constructed in Japan lies in the fact that capacity factor of the CGS is very low. A previously proposed profit index has the advantage that it makes it easily possible to evaluate the economic viability of a CGS based on its various fundamental economic and technological factors determining its economics. Sensitivity analyses of the various factors can also easily be performed.
