Gas Rates, Tariff and Filings

As one of the fastest-growing natural gas providers in North Texas, CoServ’s service area has also grown substantially over the past decade. This growth means there are more costs (equipment, infrastructure, personnel) associated with providing our customers with safe and reliable gas service. Despite this growth, CoServ has not increased our gas rates since 2009 and remains committed to providing our service at an affordable cost. The new gas rate went into effect Sept. 1, yet our prices are still substantially lower than the other natural gas providers in North Texas.

On average, our residential Customers can expect an increase in their bills of $8-$10 per month during hot weather and a decrease in their bill of $2-4 per month during cold weather. The customer charge will increase by $8.47 (to $15) but the usage rate will decrease. This should help with the fluctuations of gas usage per year and allow customers to have more equalized bills throughout the year.

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. 

You can see our rates below:

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 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.
