This allows liquid natural gas (LNG) to be pumped into the system, providing a backup source in case hurricanes or other problems interrupt service from Louisiana. In late September 2007, the Georgia Public Service Commission voted to allow AGL to construct a pipeline from the shipping terminal at Elba Island to connect with other pipelines across the state, via a pipeline that already runs across the mid-state.

The wholesale division was known as Atlanta Gas Light Services ( AGLS) for some time. AGL's retail division is Georgia Natural Gas ( GNG), and is one of around a dozen remaining resellers. The move was generally regarded as a failure, as it was not shown to have reduced prices for consumers, only making it more complicated for them to choose among 19 different marketers selling the same gas going through the same pipes as before. Under Governor Zell Miller, the Georgia General Assembly forced it to divide into retail and wholesale divisions and compete with other retailers, starting in 1998. The company was originally the direct provider of natural gas, becoming a regulated monopoly under the Georgia Public Service Commission (PSC). It provides distribution and metering to more than 1.6 million residential, commercial, and industrial customers in 243 communities throughout the state of Georgia. For financial reporting, their fiscal year ends on December 31st. It was founded in 1856 and is headquartered in Atlanta, as is AGL Resources. Atlanta Gas Light Co is primarely in the business of natural gas distribution. The Company distributes natural gas to residential, commercial, and industrial sectors. Atlanta Gas Light Company ( AGLC), commonly still known as Atlanta Gas Light ( AGL), is the largest natural gas wholesaler in the Southeast U.S., and is the leading subsidiary of parent company AGL Resources.
