Understand Your Bill

We want to make it easy for you to understand the charges that appear on your bill. Here you'll find explanations on how your bill is calculated.

What is the Rate Structure?

The Oklahoma Natural Gas residential rate structure has been simplified to make it easier to understand. There are two different rate plans to better match your individual natural gas consumption.

  • Plan A is designed for lower-volume customers whose annual consumption is less than 50 Dekatherms* per year.
  • Plan B is for larger-volume customers whose annual consumption is 50 Dekatherms* or more per year.

Remember, these plans only affect what Oklahoma Natural Gas charges you for service and delivering the gas. The cost of fuel—the natural gas you consume—is separate and is based on the amount Oklahoma Natural Gas actually paid to buy the natural gas on your behalf. The company makes no profit on the sale of natural gas.

What are the different charges listed on my bill?

  • Cost of Gas (COG) / Customer Fuel Cost
    Cost of Gas (referred to as Customer Fuel Cost in Oklahoma) includes the cost the company pays for natural gas, as well as related storage and transportation costs. The COG may also contain other charges approved by the appropriate regulatory authority. State statutes or regulations do not allow the company to mark up the cost of gas.
  • Customer Charge or Service Charge
    Customers pay a Customer or Service Charge to help recover the fixed costs of providing natural gas service. Fixed costs include bill processing, meter reading, meter equipment, service line maintenance and customer service personnel.
  • Delivery Charge
    Customers pay a Delivery Charge to have natural gas delivered to their residence or business. The charge is based on billed gas usage and may vary monthly.
  • Cost of Service (Oklahoma)
    Cost of Service includes the Service Charge and Delivery Charge, as well as additional fees related to ensuring that gas and related services are available when you need them.
  • MDQ FEE (Oklahoma)
    The MDQ FEE (Maximum Daily Quantity) represents a portion of the cost associated with maintaining the company’s ability to meet its customers' needs during times of peak demand. This charge applies only to certain rates.
  • Temperature Adjustment/TAC (Oklahoma)
    The Temperature Adjustment offsets the impact of weather variations. It is based on historical weather information and has the effect of reducing bills in colder-than-normal weather and increasing bills in warmer-than-normal weather.
  • Riders and Other Fees
    Are designed to cover a variety of expenses related to making sure that you have service when you need it. These charges are not included in the basic rates because they may fluctuate.
  • Franchise Fee
    The Franchise Fee is a tax which we pay to a municipality in order to operate within the city and use its rights of way for our pipelines. A franchise election is held periodically to determine if we can retain this privilege. Oklahoma Natural Gas Company bears the expense of this election.
