What Chattanooga Gas does

Chattanooga Gas is a regulated natural gas distribution utility serving approximately 72,000 residential, commercial, and industrial customers across Hamilton and Bradley counties in southeast Tennessee, including the Chattanooga, Cleveland, Red Bank, East Ridge, Lookout Mountain, and Signal Mountain communities. Founded in 1890 and headquartered operationally in Chattanooga, the company operates underground pipeline infrastructure, meters, pressure regulation systems, a 24/7 Gas Control Center, and a Liquefied Natural Gas (LNG) plant for supply management. It is a wholly owned subsidiary of Southern Company Gas, itself a wholly owned subsidiary of Southern Company (NYSE: SO), one of the largest energy holding companies in the United States.

The company's revenue model is a regulated subscription/recurring utility model: residential customers are billed monthly under a TPUC-approved tariff with a base rate component plus a per-therm commodity cost pass-through (the company does not profit on the gas commodity itself), while commercial and industrial customers are billed under separate tariff schedules, with optional transportation service allowing large-volume customers to purchase gas from certified marketers and use Chattanooga Gas's pipeline for delivery. The Annual Rate Review Mechanism (ARM) allows recovery of capital costs through rate adjustments; the most recent approval of $3.8 million took effect September 1, 2025, raising the typical residential bill by $2.34/month (5.7%) to recover 2024 capital expenditures. Distribution channels include the My Account online portal, AutoPay direct debit, phone customer care, authorized payment locations, and Electronic Data Interchange (EDI) for commercial customers.

Chattanooga Gas executes a Pipeline Replacement Program (PRP) targeting more than 110 miles of aging infrastructure for modernization with plastic and steel pipes, supported by federally-mandated pipeline integrity management, cross-bore inspection programs, and excess flow valve (EFV) installations. Customer-facing programs include the Shield of Warmth and Warm Neighbors bill assistance funds, residential and commercial rebates for high-efficiency equipment conversion, and a Natural Gas Preferred Partner program for contractors. The company is led by Walt Farrell, President and CEO, who also oversees Atlanta Gas Light; the two utilities together serve approximately 1.8 million customers across two states.

Revenue model

1. Natural Gas Distribution — Residential: Chattanooga Gas distributes natural gas to approximately 69,000–72,000 residential customers in Hamilton and Bradley counties, Tennessee. Revenue is generated through regulated tariff rates approved by the Tennessee Public Utility Commission (TPUC), which include a base rate component plus a per-therm commodity cost pass-through. The company does not profit on the commodity cost of gas, passing market costs directly to customers. Residential revenue is subject to the Annual Rate Review Mechanism (ARM), which allows recovery of spent capital costs and operating expenses through rate adjustments.
2. Natural Gas Distribution — Commercial & Industrial: Commercial and industrial customers receive natural gas delivery under separate tariff schedules. Business customers can opt for EDI (Electronic Data Interchange) for automated billing and transaction processing, and AutoPay for direct debit payments. The company offers transportation services allowing large customers to purchase gas from certified marketers while Chattanooga Gas delivers it through its pipeline system.
3. Pipeline Replacement Program (PRP) Capital Recovery: Infrastructure investment recovery through the ARM process. The company invests in pipeline replacement — the PRP aims to replace over 110 miles of aging pipelines with modern plastic and steel pipes — and recovers these capital costs through rate adjustments approved by TPUC.

Partnerships

Four partnerships are on record, tiered core and minor.

• Tennessee 811 (Tennessee Underground Utility Protection Services)coreStrategic or Co-development PartnerTennessee 811 is the state's designated call center for underground utility damage prevention. Chattanooga Gas works with Tennessee 811 to ensure that professional locators are dispatched to mark underground utility lines before digging projects. Calling 811 at least three business days before digging is required by law for both homeowners and professional excavators. The partnership is essential to Chattanooga Gas's pipeline safety program and prevents damage to its underground infrastructure.
• American Gas Association (AGA)minorOthersThe American Gas Association, founded in 1918, represents more than 200 local energy companies across the United States. AGA provides industry advocacy, safety standards development, research, and networking for its member utilities including Chattanooga Gas. The AGA Blue Star Seal of Approval is referenced by Chattanooga Gas as a quality indicator for natural gas appliances.
• Common Ground Alliance (CGA)minorStrategic or Co-development PartnerThe Common Ground Alliance is a national nonprofit organization dedicated to preventing damage to underground utility infrastructure and protecting those who live and work near these assets. CGA promotes safe digging practices and awareness through shared responsibility among all stakeholders. Chattanooga Gas is a member and participant in CGA initiatives.
• Chauncey Black of BlackstreetminorGTM or Marketing PartnerChattanooga Gas partnered with Grammy award-winning singer-songwriter Chauncey Black of Blackstreet to record a remix of the 90s hit 'No Diggity' as a safe digging awareness campaign. The campaign promotes calling 811 before any outdoor digging project. Black himself recorded the witty remix to deliver the safety message to homeowners and contractors across the country.
