Rate Components

Natural Gas Rates are comprised of three distinct components:

  1. Monthly availability fee: The monthly availability fee is determined by the type of service the customer receives. The fee is charged each month regardless of the amount of natural gas used.
  2. Commodity rate: The commodity rate is determined by the type of service the customer receives and is based on the cost of operations allocated to each type of customer. This rate is applied to each therm of natural gas metered.
  3. Purchased Gas Adjustment: The purchased gas adjustment is determined by the cost of natural gas and its transportation to the AUB natural gas distribution system. This rate is applied for each therm of natural gas metered.


Natural Gas Measurement Units

Natural gas is metered in volumetric units of one hundred cubic feet (ccf). The volume is converted to heat value of therms. Each therm contains 100,000 btus of energy. The international definition of a standard ccf contains one therm of energy. The natural gas normally delivered to the AUB natural gas distribution system contains between 103,000 and 104,000 btus. This amount varies monthly. Because of the additional heat value per ccf and therm rates there is not an exact correlation between the metered volume and the per therm charges.


The purchased gas adjustment and the heat value conversion are calculated monthly. 


Commercial/Industrial Gas Rate Schedules

AUB offers 10 commercial and industrial rate classes. The various classes are based on usage, demand, interruptible status, and other variables. Please use the links below to see detailed explanations and conditions for each rate class. Don't hesitate to call AUB for any needed clarifications.
