Purchased Gas Factor (PGF) – This number represents our wholesale costs for the gas you used during the billing cycle. The PGF does not include any profit or markup. It reflects only the wholesale cost of the gas itself, plus the cost we pay to transport it from our supplier to CoServ. Because complete information regarding our gas costs isn’t available at the time we send your bill, the PGF is an estimate. However, we adjust any over-charges or under-charges each month. Get more details on the PGF.

Weather Normalization Adjustment (WNA)  – During the December through May billing periods, you'll notice a line item called the Weather Normalization Adjustment (WNA) – which affects the monthly Ccf usage charge. WNA is standard within the natural gas utility industry and protects both the customer and the gas provider. The calculation is based on normal temperatures, and it provides an adjustment if temperatures are higher or lower than normal. When the weather is colder than normal, the WNA will reduce the Ccf usage charge to a normal level. When the weather is warmer than normal, the WNA will increase the Ccf usage charge to a normal level.

Usage Charge/Volumetric Rate – The usage/volumetric rate is the charge for delivering natural gas through the CoServ Distribution system. 

Gas Rate Case Expense – During the recent rate case, CoServ Gas incurred legal and consulting fees to prepare and pursue the rate case.  Pursuant to the Railroad Commission of Texas (RRC) order, CoServ Gas reimbursed the legal and consulting costs of the municipalities that intervened in the rate case. The RRC allows CoServ Gas to recover these costs over an approximate 24 month period at of rate of $0.00333 per Ccf consumed. The recovery of these fees is annually reviewed by the Commission and in the event of an over-recovery, the over-recovery amount is ultimately returned to the customers.

Please remember that the amount of change in your bill will vary depending upon other factors like the size of your home, amount of gas that you use, taxes, etc. Review the CoServ Gas tariff for full details regarding rate schedules.
