... a click on any stratum will open a text file containing the average hourly demand by stratum, month, hour & daytype;

... a customer's usage factor times the average hourly profiled demand yields the estimated hourly demand of the individual customer;

... the sum of the estimated hourly demands of each & every customer in the ESCOs portfolio yields the ESCOs estimated hourly load obligation.
