AGL Pass-Through Charges

Have you ever looked at your natural gas bill and wondered what AGL Pass-Through Charges are? AGL Pass-Through Charges are a reflection of Atlanta Gas Light’s costs for maintaining the natural gas pipelines and storage facilities, as well as reading your meter each month. Read on to learn more about AGL and how your Pass-Through charges are calculated.

Who is AGL?

Atlanta Gas Light Company (AGL) is the company that owns the pipeline system that delivers natural gas to your property. Rather than receiving a separate bill from AGL, AGL Pass-Through Charges are applied and are sent to your natural gas marketer (in your case, Gas South) and those charges are “passed through” to you – without any additional cost or mark-up. You’ll see the charges from AGL on your Gas South bill, just like in the sample bill below.

When will I get charged the AGL Pass-Through Charges?

AGL Pass-Through Charges are assessed on the 20th of every month for the next month of service. AGL assesses the full monthly pass-through charges each month regardless of the actual number of days you receive service or the amount of gas you use in that particular month. You’ll see the monthly AGL Pass-Through charge on each bill as the AGL charges are spread over an entire year rather than when gas is used.

How are AGL Pass-Through Charges calculated and what exactly do the AGL Pass-Through Charges cover?

Your AGL Pass-Through Charges are exactly the same regardless of which natural gas marketer you choose. These charges are calculated by AGL and regulated by the Georgia Public Service Commission.

AGL Pass-Through Charges vary by month and are independent of your current month’s gas usage. They will vary by month and tend to be higher in the winter months.

What are the factors AGL uses to calculate your monthly charges?

The AGL charges include:

  • Customer Charge: A fixed monthly fee for gas connection to your home or business.
  • Ancillary Service: Covers the cost of AGL to read your meter.
  • Social Responsibility Fee: Covers the cost of funding the Senior Citizens’ Discount Program for low-income customers. (This does not apply to customers who receive the senior citizens’ discount.)
  • Strategic Infrastructure Development and Enhancement (STRIDE): Covers the cost of specific Georgia Public Service Commission-approved programs to maintain the integrity and reliability of the AGL pipeline system.

What charges are based on your DDDC?

  • Dedicated Design Day Capacity (DDDC): A charge that recovers costs associated with delivering gas to your home or business.
  • Peaking Service: Covers the fixed cost of operating company-owned above-ground storage facilities. This ensures an adequate supply of gas on the coldest days of the year. This service is only charged to customers in certain areas of the state.
  • Franchise Recovery Fee (FRF): Recovers fees paid by AGL to local governments for the use of public rights-of-way for natural gas lines and other facilities.
  • Environmental Response Cost (ERC) Recovery Fee: Recovers expenses related to cleanup of former manufactured gas plant sites.

  3. Speaking as a guy across the pond who has to pay the gas bill, I really wish we had a blog like this over at Detroit Edison (our gas company). The outreach really helps to explain things. Kudos to you guys. We just get a phone number to call and a website that barely works.

  5. Good afternoon Lauren,

    I just got my January bill and my AGL pass through charge is $34.76 My gas is 86.14….Plus I have to pay for customer service and tax. Tax I know can’t stop that. But why is the pass through so high. My husband and I are retired we are careful about the temp in the house. Is this a normal charge? its almost 1/2 of my bill.

    Please let me know if there is anything we can do to lower that charge.

    Thank you.

  6. I have never in my life had such an issue with a gas company. Not only did my bill deceive me saying I owe less than I did then this company has added on late fees when my bill told me it was lower and I paid exactly what was on my bill. On top of that the only thing we have on gas is hot water and our bill is almost $100 a month for a small 2 bedroom apt where only 2 people live? This is outrageous and on top of that we have this “pass through charge” which is an extra $20 every month!!! I am outraged at this company!!!!!

    1. Sarah, thank you for your comment. I’ll be sending you an email to the address listed with your comment to try to help. Thank you!

  7. I received my “Friends and Family” renewal offers from you and was disappointed that after all these years with you, you offer me a 12 or 18 month fixed rate plan that is twice the cost of your published 6 month fixed rate plan on You state that I MUST choose a 12 or 18 month fixed rate or pay the higher variable rate. I don’t HAVE to do either because I could CHANGE carriers. You have 2 competitors with LOWER per therm rates for 12 months fixed AND why am I paying a AGL fee for reading meter/maintenance and ANOTHER customer service fee to you???? I hate utilities, you get shafted by everyone double dipping into your wallet.

    1. Hi Kurt, thank you for your comment. My colleague tried to call the phone numbers on your account to try to help, but they are not working. Please email the best phone number to reach you so we can help. Thank you!

  8. I just received my 2nd gas south bill. I do not recall hearing about the AGL fee when I signed up. On my 2nd bill the charge was $20.71 (August fee) not including taxes and customer service fee, my gas charges was $5.34, and what happened to the $5 credit for 5 months and will the AGL fee be that amount every month?
