How Atlanta Gas Light Billing Works

Understanding how Atlanta Gas Light billing works helps you anticipate costs, catch errors, and manage your natural gas expenses effectively. This guide covers the complete billing process from meter reading to payment.

Your bill reflects usage during a specific billing period, typically 28-32 days. The bill is generated after your meter is read (or estimated) and combines charges from both AGL and your gas marketer.

AGL reads meters on a monthly cycle, with your specific reading date depending on your service address and route. Most meters are read between the 1st and 28th of each month.

Your meter measures natural gas usage in cubic feet (CCF), which is converted to therms for billing purposes. One CCF equals approximately 1.03 therms, depending on the heat content of the gas.

After your meter is read, your bill is typically generated within 2-3 days. The bill shows:

• Service period: The dates covered by this bill
• Previous and current readings: Used to calculate usage
• Therm usage: The amount of gas consumed
• Due date: Typically 21 days after the bill date

Bills are sent via mail or email (if enrolled in paperless billing) and can be viewed online through AGL's customer portal.

Your total bill is calculated as follows:

1. AGL Customer Charge: $20.00 (fixed)
2. AGL Delivery Charge: Therms × delivery rate
3. AGL Surcharges: Various per-therm fees
4. Marketer Supply Charge: Therms × your contracted rate
5. Marketer Monthly Fee: If applicable
6. Taxes and Fees: State/local taxes

The total of all these components equals your amount due.
