The Peak Load Ratio variable reflects the ratio of the peak implied by a simplified time-sliced load shape versus the actual peak load on a system (i.e. if you were to consider every hour in the year, as opposed to only the average for each time slice). Time slice configurations used in LEAP reflect some degree of averaging of how the actual load on a system varies. For example they may miss some seasonal variations or some hourly variations in load. This variable allows you to adjust for this loss of fidelity and so more accurately reflect actual and likely future system peak loads.

You can enter a value for the Peak Load Ratio variable in two ways:

1. You can manually enter a number between 0% and 100%, which you can calculate outside of LEAP by dividing the peak load in LEAP by the actual system peak load

2. You can use the PeakLoadRatioFromYearlyShape function to link to the values associated with yearly shapes. However, this only works if you created that yearly shape by importing hourly values, and not by specifying time-sliced values. Otherwise, LEAP has no way of knowing what the actual system peak load is.
