Atlanta Gas Light Company (AGLC), widely recognized as Atlanta Gas Light (AGL), stands as the foremost natural gas wholesaler in the Southeast U.S. and operates as a prominent subsidiary under Southern Company Gas. Established in 1856 and based in Atlanta, AGL provides natural gas services to more than 1.6 million customers spanning residential, commercial, and industrial sectors throughout 243 communities within Georgia.
Initially functioning as a regulated monopoly overseen by the Georgia Public Service Commission (PSC), AGL was mandated by the Georgia General Assembly during Governor Zell Miller’s administration to divide into separate retail and wholesale entities and enter into competition with other retailers beginning in 1998. Although this deregulation did not lead to lower prices for consumers, it introduced complexity by allowing 19 different marketers to sell gas using the same pipeline system. The retail division of AGL is known as Georgia Natural Gas (GNG), one of roughly a dozen remaining resellers, while the wholesale segment operated under the name Atlanta Gas Light Services (AGLS).
In September 2007, the PSC authorized AGL to build a pipeline linking the Elba Island LNG terminal with pipelines across the state. This infrastructure upgrade improved supply security by permitting LNG to be injected into the system as a contingency during events like hurricanes or other supply interruptions.
Southern Company acquired AGL Resources in August 2015 through a $12 billion transaction, unifying Georgia’s energy market by merging AGL’s natural gas operations with Southern’s ownership of Georgia Power, which is the primary electricity provider in the state.
