Keep in mind that CoServ Gas, like other Texas gas utilities, does not mark up the price of natural gas for a profit. Rather, our revenue comes from the cost of delivering gas to your home or business.

Weather Normalization Adjustment (WNA):

During the November through May billing periods, you'll notice a line item called the Weather Normalization Adjustment (WNA) – which affects the monthly Ccf usage charge. This calculation is quickly becoming 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 colder or warmer 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, it will increase the Ccf usage charge to a normal level. Below is a chart that illustrates how the WNA balances the effect of weather on your bill:
