Hello!
 

Is there are timeframe that a green power purchase must be made, per the LEED Reference Guide or other rating system requirements? I thought I had come across a timeframe like "within 12 months of substantial completion" (or something similar), but cannot find anything about when the actual purchase should be made.

Our project is currently about 14 months away from substantial completion but the team would like to make the Green Power purchase now as to lock in the rates (that have been so volatile lately!).

Any insight is appreciated. Thank you!
