I am trying to run a PPA Single Owner (utility) model scenario with a 8yr Analysis Period and a 8 yr loan term, 52% debt, with ITC and MACR with bonus depreciation. The program crashes when I attempt to run the simulation. I can change the Analysis Period to 10 yrs and it runs fine. Any Analysis Period less than 10 yrs crashes.
In SAM 2016.3.14 r1, there is a problem with the PPA financial models when you use an analysis period less than 11 years. The only way to avoid the problem for now is to use an analysis period of 11 years or greater. We will fix this issue in the next update to allow for shorter analysis periods. This issue does not affect the residential and commercial financial models.
In general, always be sure that the IRR target year and loan period (debt tenor) are less than the analysis period, and for the partnership flip models, that the target flip year is less than the analysis period. Also be sure that the analysis period is greater than the number of years in any accelerated depreciation schedules.
Best regards,
Paul.
