Gas Supply Gas Supply Service is the portion of your service for which you can shop for an alternate supplier, or energy service company. Our charges for gas supply are based upon market conditions and will vary depending on where you live or do business. If you choose an alternate supplier depending on your service class, the price will be what you agree upon with that supplier. If you have an alternate supplier and have concerns related to the Gas Supply Charge portion of your bill, please contact your supplier.

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.
