expenses, rate of return, inflation, etc. Once a scenario has been defined, it must be logged to
be used for future analysis.
Project Summary
Once a Feedstock Scenario and a Power Plant Scenario have been created and logged, it is
possible to calculate the estimated cost of delivered energy. One may select a Power Plant
Scenario and input different Feedstock Scenarios to evaluate the economic impacts of various
options. One may also conduct sensitivity analysis on the Project Scenarios to understand the
impacts of fluctuating inputs on the final energy cost. Project Scenarios can also be logged for
future reference.

Basic Cost Calculations
These are the cost calculations internal to BioPET that estimates project costs throughout the
process. They are offered here to provide the user with enough information to understand the
calculations and allow the user to manipulate the entries to satisfy individual project concerns.
Please refer to the BioPET software manual in Appendix A for even more detail.
