15-Minute vs. 30-Minute Demand Instantaneous peak is what we build for and are obligated to serve. The cost of meeting this obligation doesn t change irrespective of how measured. Measuring over a wider period of time will yield a lower measured peak demand. Thus, demand charges go up with a wider measurement period. 12
