Atlanta Gas Light Company Data Access Guide
Atlanta Gas Light (AGL) is Georgia's largest natural gas local distribution company, owning the pipes and meters but not selling gas. In Georgia's deregulated gas market, customers buy commodity and receive bills from certificated marketers, while AGL handles delivery, metering, and consumption data via its Energy Connection Center and marketer EDI.

Rate Schedules & Tariff Analysis
AGL bills decompose into a non-shoppable PSC-regulated distribution portion (Customer Charge, Firm Distribution, DDDC capacity, and various pass-throughs) and a shoppable commodity portion set by competitive marketers. The DDDC capacity charge — driven by each meter's coldest-day peak demand — is typically the largest AGL component, so peak-demand reduction is the primary lever on distribution cost, while marketer selection is the lever on commodity cost.
Atlanta Gas Light Company Rate Schedule List
| Schedule | Applicability |
|---|---|
| AGL Base / Distribution | PSC-set pass-through on every C&I bill |
| DDDC Capacity Charge | Peak-demand-based, recalculated annually each August |
| Commodity (Marketer) | Competitive per-therm rate, shoppable |
| GRAM Adjustment | Annual PSC distribution rate review |
Atlanta Gas Light Company Rate Features & TOU Details
- LDC delivery-only model; commodity bought from competitive marketers
- DDDC capacity charge based on coldest-day peak, recalculated every August

Limitations & Considerations
- ⚠AGL does not bill customers directly; billing data must come from the chosen marketer.
- ⚠No Green Button / ESPI program and no public developer API — data access is largely manual or via marketer EDI / aggregators.
- ⚠True 15-minute interval data is limited; standard AMR provides daily reads, with finer granularity only for eligible commercial meters by request.
- ⚠Consumption data requests typically take 5-10 business days and require written customer authorization.
- ⚠AGL distribution charges (DDDC, base, pass-throughs) are PSC-set and not shoppable; only the marketer commodity rate is competitive.
Atlanta Gas Light Company Data Access FAQ
Why doesn't Atlanta Gas Light send us a bill?▾
Because Georgia has a deregulated natural gas market. AGL is the local distribution company that owns the pipes, reads the meter, and maintains the system, but does not sell gas. You buy gas from a Georgia PSC-certificated marketer (such as Gas South, Georgia Natural Gas, SCANA Energy, or Constellation), and that marketer issues your bill, including AGL's pass-through distribution charges.
How does a commercial customer get consumption (usage) data from AGL?▾
Submit a Commercial Project Data Request through atlantagaslight.com/business or contact the Energy Connection Center (800.599.3770 / G2constructionoperat@southernco.com) with your service-location number and date range. AGL provides historical consumption (typically up to 3 years) as CSV/spreadsheet, usually within 5-10 business days. Hourly or 15-minute granularity may be available for eligible commercial meters on request.
Can a third party (consultant or aggregator) access our gas data?▾
Yes, with written customer authorization. Options are: (1) request consumption data directly from AGL's Energy Connection Center, (2) work through your certificated marketer, or (3) use a data platform — Nectar provides API access to this utility's billing and consumption data (see docs.nectarclimate.com). AGL has no public utility API and no Green Button program, so automated access flows through marketer EDI or platforms like Nectar.
What is the DDDC charge on our bill?▾
Dedicated Design Day Capacity (DDDC) is AGL's distribution capacity charge — the cost of reserving pipeline capacity for your peak (coldest-day) demand. AGL recalculates each meter's DDDC factor every August based on prior-winter peak usage, and the annual capacity charge is billed across the year on a fixed monthly percentage schedule (heaviest in winter). It is the largest AGL pass-through cost driver for most accounts.
How do we lower the AGL portion of our gas bill versus the marketer portion?▾
AGL's distribution (base/DDDC/pass-through) charges are set by the Georgia PSC and are the same regardless of marketer — you cannot shop those. What you CAN shop is the commodity (per-therm) rate from competitive marketers; as of June 2026 the lowest advertised commercial rate in Georgia was about $0.622/therm. Reducing winter peak usage lowers your DDDC factor over time, and choosing a competitive marketer rate reduces the commodity portion.
