Costs for Gas Supply purchased from us are prorated based on the number of billing days within each monthly rate period. For example, a customer who is billed from November 5 to December 5 would be charged 25 days at the November rate and 5 days at the December rate. The rates set forth below do not include any gross revenue taxes.
The months denoted with an asterisk (*) have been adjusted to reflect over/under recoveries of gas cost from prior periods.
