Atlanta Gas Light was incorporated in 1856 in Atlanta, Georgia, making it one of the oldest natural gas utilities in the United States. The company was founded before the Civil War and began distributing manufactured gas for street lighting. The company transitioned to natural gas distribution as pipeline infrastructure expanded through the southeastern United States in the mid-twentieth century.
Atlanta Gas Light was historically owned by its predecessor holding company AGL Resources. In 1907, the company became a publicly traded entity. It grew steadily through the twentieth century, expanding its distribution network across Georgia as the state's population grew. By the early 2000s, Atlanta Gas Light served approximately 1.5 million customers.
In 2016, Southern Company acquired AGL Resources, the holding company that owned Atlanta Gas Light, for approximately 12 billion dollars including debt. The acquisition was the largest in Southern Company's history and transformed Southern Company into a combined electric and natural gas utility. Following the acquisition, AGL Resources was renamed Southern Company Gas, and Atlanta Gas Light operates within that segment.
Pipeline modernization has been a core operational focus since the 1990s. Between 1998 and 2018, the company replaced a significant portion of its older cast iron and bare steel distribution pipes, substantially reducing methane emissions and improving service reliability.

Together, these subsidiaries serve over 9 million customers across multiple states.
Is Southern Company publicly traded?
Yes. Southern Company is publicly traded on the New York Stock Exchange under ticker SO. The company is owned by its shareholders, with no single controlling shareholder. Major institutional shareholders include Vanguard Group, BlackRock, and State Street Corporation.

Southern Company was founded in 1945 as a holding company for various utility operations in the southeastern United States. The company has grown through consolidation of regional utility companies and strategic acquisitions over the decades.
How many customers does Southern Company serve?
Southern Company serves over 9 million customers through its subsidiaries.

Who leads Southern Company?

Atlanta Gas Light's primary environmental metric is methane emissions from its distribution system. Between 1998 and 2018, the company replaced substantial portions of aging cast iron and bare steel pipelines with plastic and coated steel pipes. The company reported reducing annual methane emissions from its distribution system by approximately 60% over that period, coinciding with a 25% network expansion. The US Department of Energy cited the program as one of the earliest and most successful pipeline modernization efforts in the country.
The company uses cross-compression technology during pipeline maintenance to capture and return natural gas to the system rather than venting it to the atmosphere, reducing fugitive emissions during routine operations.
Southern Company Gas, Atlanta Gas Light's segment parent, has explored renewable natural gas (RNG) purchase agreements in line with Southern Company's broader clean energy commitments. Southern Company has set a goal of net-zero greenhouse gas emissions by 2050 and a 50% reduction from 2007 levels by 2030.
Atlanta Gas Light operates under the regulatory jurisdiction of the Georgia Public Service Commission on rates and service standards, and under EPA rules for pipeline emissions reporting. No significant environmental enforcement actions against Atlanta Gas Light have been publicly reported as of June 2026.
The US Department of Energy identified Atlanta Gas Light's pipeline modernization program as one of the earliest and most successful in the country, citing the scale of cast iron pipe replacement and associated methane reduction achieved between 1998 and 2018.
In 2024, Atlanta Gas Light was named a finalist for the Southern Gas Association (SGA) Awards for its community partnership program with Goodr, a food rescue nonprofit addressing food insecurity in Georgia.
Southern Company, Atlanta Gas Light's ultimate parent, was named a 2025 Military Friendly Employer, a designation that covers Southern Company Group subsidiaries including Atlanta Gas Light.
Customer Billing Complaints: Atlanta Gas Light has a history of customer billing complaints logged with the Georgia Public Service Commission and the Better Business Bureau. Complaints have primarily related to delivery fee structures, meter reading disputes, and confusion about the separation between distribution charges (Atlanta Gas Light) and commodity charges (the customer's chosen marketer). These are routine for a large regulated utility operating in a deregulated commodity market.
Georgia Dual-Utility Market Concentration: The combination of Atlanta Gas Light (natural gas distribution) and Georgia Power (electric distribution) under Southern Company's ownership has been raised as a market concentration concern by consumer advocacy groups in Georgia. Critics argue that Southern Company's control of both distribution monopolies limits Georgia regulators' ability to independently assess energy transition options. No antitrust enforcement action has been taken as of June 2026.
Natural Gas Infrastructure and Climate Policy Tension: Atlanta Gas Light's business model depends on continued natural gas consumption. As Georgia moves to meet federal emissions standards and as electric heat pumps become cost-competitive with gas heating, the long-term demand outlook for residential gas delivery is uncertain. Environmental groups have argued that Southern Company's investment in extending natural gas distribution infrastructure runs counter to state and federal decarbonization goals. Southern Company disputes this characterization, citing natural gas as a transition fuel.
No Product Recalls: Atlanta Gas Light does not manufacture consumer products. No product safety recalls related to Atlanta Gas Light are recorded by the Consumer Product Safety Commission as of June 2026.
