Load Profiles The load shape data below are structured in Excel (xls) files as follows:
  • Columns—Represent Hour 1 through 24
    (e.g., Column A = Hour 1 or Hour ending at 1 a.m.)
  • Rows—Represent Day 1 through 365
    (e.g., Row 1 = Day 1 or January 1)

There are 8,760 values in each spreadsheet. These are unitized loads, whereby the sum of the calendar year equals 1 (or is very close to it). The values in each cell represent the fraction of yearly energy used for that hour of the year.
