A load profile is created using measurements of a customer's electricity use at regular intervals, typically one hour or less, and provides an accurate representation of a customer's usage pattern over time.
Since this requires the use of expensive interval meters, it has not been cost-effective to meter all accounts this way. So, many utilities conduct load studies (primarily for marketing, rate design, system planning and load profiling purposes) using interval metering on samples of customer groups or segments and use the results to represent the segment’s usage pattern. Segment load profiles for Voice Your Choice have been calculated from such load studies.
Day Type Profiles
Three profiles – week day, Saturday and Sunday/holiday – were developed for each month and each segment. The profiles are used to calculate the variable price and in the development of load serving entity (LSE) load for the New York Independent System Operator. The segment load profiles effective January 1, 2003 are at the service class level, whereas several profiles effective November 1997 through December 2002 differentiate between revenue classes within the service class.
