Gas Rates

Residential Natural Gas Rate

Commercial/Public Authority Natural Gas Rate

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 weather is colder than normal, the WNA will reduce the Ccf usage charge to a normal level. When weather is warmer than normal, the WNA will increase the Ccf usage charge to a normal level.

*For customers using more than 4,000 ccf per year, the WNA charge/credit does not apply.
