Suppose that a company has hired a solar consultant who says that current conditions have changed. According to the consultant, the inflation rate (growth rate) for maintenance and upgrades should actually be 5% (instead of 3%) and the PPA price growth rate should be only 2% (instead of 4%). In addition, 15-year PPAs are less common now and most utilities will only sign up for a 10-year PPA so the project forecast should end at project period 10.
