Chattanooga Gas Company Data Access FAQ
How do commercial customers get usage data from Chattanooga Gas programmatically?▾
Enroll in the EDI trading partner program. EDI 814 Customer Historical Usage Requests return monthly consumption data in ANSI X12 format, EDI 810 delivers electronic bills, and EDI 820 handles payments. Start by emailing edimsg@aglresources.com to get the enrollment package, sign the NAESB EDI Trading Partner Agreement, and complete message testing.
Does Chattanooga Gas provide interval (sub-hourly) gas data?▾
No. The utility runs AMR metering with monthly reads only — there is no 15- or 30-minute interval data for customers or third parties. The My Account portal shows monthly usage with a 13-month comparison; EDI 814 likewise returns monthly history. Special requests go to 866.643.4168.
How can an energy consultant access a customer's Chattanooga Gas data?▾
Through EDI with customer authorization. Obtain a signed authorization, register as a trading partner via edimsg@aglresources.com with your customer list, execute the NAESB agreement, and configure VAN or direct transmission. Once tested and activated, you can pull monthly usage via EDI 814 and receive bills via EDI 810 for each authorized account.
Does Chattanooga Gas support Green Button or a public API?▾
No. There is no Green Button DMD/CMD, ESPI support, REST API, or developer portal — typical for a gas-only LDC of this size. EDI is the only programmatic channel; the portal offers PDF bills without CSV export.
Is Chattanooga Gas the same as EPB Chattanooga?▾
No. EPB is Chattanooga's municipal electric (and fiber) utility, while Chattanooga Gas Company is the investor-owned natural gas distributor (a Southern Company Gas subsidiary) serving Hamilton and Bradley counties. Facilities in Chattanooga typically deal with both: EPB for electricity and Chattanooga Gas for natural gas.
Where are Chattanooga Gas rates published?▾
Business pricing and rate plans are published at https://www.chattanoogagas.com/business/pricing-and-rate-plans.html under TPUC tariff No. 1 (effective November 1, 2018). The latest annual rate review took effect September 1, 2025; the Tennessee Public Utility Commission regulates all rates.
