About

Who is Gas South?

Registered as Gas South District LLC, Gas South uses this legal name for state public-utility-commission filings and customer contracts. The trading name on bills is the shorter, more recognisable form.

The company is headquartered in Atlanta, GA, where it runs senior management, customer operations and regulatory liaison with state commissions.

Gas South was established in 2006. A longer track record means more years operating under state-commission rules and a wider history of customer feedback, billing and regulatory interactions.

Gas South is part of the Cobb EMC (member-owned electric cooperative) group, which provides shared governance, financial backing and a broader pool of expertise in wholesale-market trading, hedging and regulatory work.

Service availability varies by zip code within each state. Eligibility depends on your local utility's deregulation status — check on Gas South's website with your zip code before enrolling.

Plan structure

What plan types does Gas South offer?

Fixed-rate gas plans

12 and 24-month fixed-rate residential plans, typically the lowest-risk option for households who want price certainty through the winter heating season.

Variable-rate / month-to-month

No-term plans that track Gas South's monthly published rate. Higher risk during cold-snap months but flexible to switch.

Gas South Cares Senior Discount

Reduced base monthly charge for Georgia residents aged 65+; one of the few age-based discounts in the Atlanta-area gas market.

Renewable content: Gas South does not offer a renewable-natural-gas (RNG) product to residential customers as of 2026; commercial customers can purchase carbon offsets through bespoke contracts.

In a 2022 acquisition, many former Infinite Energy customers transferred to Gas South. Check the supplier line on your bill if you signed up before 2022 under another brand.

Frequently asked

Gas South — answers to common questions

Gas South is regulated by the public utility commission in each state where it operates. Reliability is best judged against your own usage profile: read recent reviews, confirm the customer-service hours match when you actually need to call, and compare the unit rate against the utility's price-to-compare for your zip code.

Plans can typically be enrolled directly on Gas South's website or by calling 1-866-762-6427. Before signing up, always compare the unit rate (¢/kWh for electricity, $/therm for gas) against your utility's price-to-compare for your zip code.

You can switch your retail supplier at any time, though early termination fees (typically $50-$200) may apply if you are on a fixed-rate plan and within the contract term. Check your enrollment letter or Terms of Service for the exact figure. Switching back to your default utility supply is always free.
