Our project has a PV array which is leased by the building owner under a 20-year power purchase agreement. However, the agreed upon rate increases 2% each year during these 20 years. Should I use the current year rate to assign a cost to the on-site generated renewable energy, or should this be an average of the escalating rate over the 20 years?

To be consistent with the utility rates you use in the energy model, I would use the current year rate.
