(A) Degree days are calculated as follows: The high and low degrees of a particular day are added together and then
averaged. If the calculated average is above 65 degrees, then the difference between the calculated average and 65 is
expressed as cooling degree days, with each degree of difference equaling one cooling degree day. If the calculated
average is below 65 degrees, then the difference between the calculated average and 65 is expressed as heating degree
days, with each degree of difference equaling one heating degree day. The daily calculations are then totaled for the
particular reporting period.
