- In AGL territory, they own the pipelines and respond to emergencies; you pick a certified natural gas marketer for your rates and billing.
- No matter which marketer you choose, your bill includes AGL’s delivery/base charges (driven by your DDDC), so compare total “all-in” costs.
- If you suspect a gas leak, leave and call AGL (and/or 911). Your marketer handles enrollments, payments, renewals, and apps.
- Confirm your address is in AGL’s service area (some Georgia areas aren’t deregulated), and look for AGL-backed equipment rebates and a senior discount that can lower your monthly costs.
Atlanta Gas Light At a Glance
First things first, let’s get to know the company. Atlanta Gas Light (AGL) is the largest natural gas distributor in the entire Southeast United States. They proudly serve approximately 1.55 million residential, commercial, and industrial customers across Georgia.
But here’s the most important thing to know: AGL is not the company that sells you the actual natural gas. Instead, they are the incredible team behind the scenes. They own, operate, and maintain the vast network of pipelines, meters, and infrastructure that delivers natural gas to your community. If you ever smell gas or have a leak, they’re the heroes you call to come fix it, 24/7. They’re like the road builders and maintenance crew for the natural gas highway, while other companies are the “car dealers” selling you the fuel.

Coverage Area & Deregulation
AGL’s service territory covers a significant portion of Georgia, but not the entire state. Their network includes major metropolitan areas like Atlanta, Savannah, Augusta, Macon, and extends to many other communities.
Now, let’s talk about the unique “deregulated” market in Georgia. Back in 1998, Georgia decided to deregulate its natural gas industry. This means that if you live within AGL’s service area, you have the power to choose the company that supplies your natural gas. These companies are called Retail Natural Gas Marketers (RNGPs).
Key Point: Only residents within the Atlanta Gas Light Company (AGLC) service territory can choose their natural gas provider. If you live in an area served by a different utility, you likely won’t have this option. So, your first step is to confirm your home is in AGL’s zone!
Choosing a retail natural gas provider (RNGP)
This is where you, as a customer, get to take control! Since AGL handles the delivery for everyone, you can shop around for the company that sells you the gas commodity itself.
Why You’d Choose (or switch to) a RNGP
Because AGL’s area is deregulated, marketers compete on rate types (fixed vs. variable), term lengths, fees, renewals, customer service, mobile apps, and extras (rewards, bill credits, or senior plans). The Georgia Public Service Commission (PSC) publishes a monthly pricing comparison and a marketer complaint scorecard that make it easier to compare. Use those first, then zero in on plan details on each marketer’s site.

Things to Consider
First, look at your annual usage (therms) and your AGL pass-through/base charges (more on those below).
- Rate Type: A fixed-rate plan locks in your price per therm for the contract term, protecting you from market spikes. A variable-rate plan can change monthly, which could be lower but also riskier.
- Contract Length: Do you want a long-term contract for peace of mind, or the flexibility of a month-to-month plan?
- Fees: Look out for hidden fees like sign-up or cancellation fees.
- Your Credit: Some marketers may require a deposit or reject applicants with low credit scores. If this happens, don’t worry! You can still sign up for regulated provider service, which requires a refundable $150 deposit that you get back after six on-time payments
- Discounts: Some providers offer senior or military discounts
How to Search For & Report an Outage
Natural gas “outages” are handled differently than electric. If you smell gas or suspect a leak: leave immediately (don’t use electronics or switches), then call AGL’s 24/7 emergency line 877-427-4321 (and/or 911) once you’re in a safe place.
For non-emergency service issues or to check if an outage has already been reported in your area, the best bet is to visit the Atlanta Gas Light website or call their customer service number. Their website typically has an outage map or status update tool.
Rebates, Discounts & Bill Help
Equipment rebates (AGL programs): AGL offers conversion and energy-efficiency rebates for swapping to or upgrading efficient natural gas furnaces and water heaters (and certain dryers). Typical residential examples include $300–$400 for high-efficiency furnaces (92%+ AFUE) and $200–$300 for qualifying storage/tankless water heaters, subject to eligibility and submission timelines. Check current terms before you buy/install.
Senior citizen discount (AGL charge): Eligible customers 65+ with qualifying income can receive a monthly discount on AGL’s charges up to $14 (this is an AGL distribution-charge credit that appears on your marketer’s bill). Ask your marketer for the AGL Senior Discount form to apply.
Bill-payment assistance: In addition to federal LIHEAP (apply through Georgia DFCS), Georgia residents may access community funds such as H.E.A.T., Project SHARE (Salvation Army), and local agencies. AGL lists assistance resources and can help point you in the right direction.
Other Useful Things to Know
The AGL pass-through (base) charge & DDDC: On every bill in AGL territory, you’ll see AGL’s charges passed through by your marketer. The biggest driver is your Dedicated Design Day Capacity (DDDC), AGL’s annual calculation of how much capacity your home needs on the coldest day. Because winter demand is higher, the PSC allocates more of the annual DDDC recovery to winter months, so your AGL portion will look seasonal even on a fixed rate. AGL explains DDDC in its tariff, and the PSC explains the month-by-month allocation.
Infrastructure Upgrades: AGL is constantly working to improve its system! For example, in mid-2025, they began a project to install over 7 miles of new pipeline in the Villa Rica area to improve reliability and meet growing demand.
