The Georgia Public Service Commission's website produces monthly charts that detail companies and their rates for natural gas. Monthly charts are available as far back as 2002.
Residents use the monthly charts to compare the cost per therm of natural gas between companies. Customers can receive service through a prepaid plan, in which they must pay for service in advance; fixed rates, which maintains the same cost over a period of time; variable rates, in which the cost can change each month; and a senior discount plan, which is available to customers age 65 or older or is based on income.
Fourteen companies provide natural gas in Georgia, as of May 2015. The unregulated-cost companies are Commerce Energy, Constellation, Fireside, Gas South, Georgia Natural Gas, Infinite Energy, Kratos of Georgia, North American Power, SCANA Energy, Stream Energy, True Natural Gas and Walton EMC Natural Gas.
Liberty Utilities, a local distribution company based in Georgia, is fully regulated by the Public Service Commission. The Atlanta Gas Light Company, to which 10 companies contribute service, offers natural gas at market rates, but its distribution service is regulated by the commission.
Residents in 84 municipalities have a choice for service: private companies or a local gas system whose costs are regulated by a municipality.
