[1] Gas South began operations in 2006 as a wholly owned subsidiary of Cobb Electric Membership Corporation.

[2] Georgia's natural gas industry was partially deregulated in 1997[3] with the passing of the Natural Gas Competition and Deregulation Act,[4] giving commercial and residential customers in many parts of the state a range of options.

Under deregulation, the local distribution company, Atlanta Gas Light Company (AGLC), elected to no longer serve as a retail gas supplier and instead solely maintain and operate the distribution system.

Following the acquisition of Infinite Energy in December 2020, Gas South now serves nearly 500,000 residential, business and governmental customers.
