The Southern Company
The Southern Company, through its subsidiaries, engages in the sale of electricity. The company offers electric service to retail customers and wholesale customers; and energy-related products and services to natural gas choice markets. It also develops, constructs, acquires, owns, operates, and manages power generation assets, as well as battery energy storage projects; sells electricity at market-based rates in the wholesale market; and deploys microgrids for commercial, industrial, governmental, and utility customers. In addition, the company is involved in the distribution of natural gas in Illinois, Georgia, Virginia, and Tennessee; distributes energy and resilience solutions; and invests in telecommunications. The Southern Company was incorporated in 1945 and is headquartered in Atlanta, Georgia.
What does it do?
Southern Company is one of America's largest electric utilities, providing power to roughly 9 million customers across Georgia, Alabama, Mississippi, and Florida. Think of it as the company that keeps the lights on, the AC running, and the factories humming across the deep South. It owns the power plants, the transmission lines, and the local infrastructure that delivers electricity directly to homes and businesses. It also has a natural gas distribution business, selling gas to homes and companies that choose their own supplier.
Southern Company is sitting at the center of one of the biggest infrastructure stories in America right now — the explosion in electricity demand driven by AI data centers, electric vehicles, and onshoring of manufacturing. Utilities like Southern are essentially toll roads for electricity, and the South is one of the fastest-growing regions in the country for new industrial development. With regulators guaranteeing it a return on investment, Southern is in a rare position: near-guaranteed profits during a period of surging demand.
How does it make money?
Southern makes money by charging customers for electricity and natural gas, generating $29.6 billion in revenue last year — up from $26.7 billion the year before, a jump of about 11%. Because it operates as a regulated utility, state regulators set the rates it can charge, which essentially guarantees a steady profit margin in exchange for reliable service. The bulk of revenue comes from retail electricity sales to homes and businesses in the Southeast. It also earns money selling excess power at market prices to wholesale buyers like other utilities or large industrial customers.
Why do investors care?
The big growth story here is electricity demand. For years, power demand in the US was flat — but AI data centers alone are expected to double their electricity consumption by 2030, and companies like Microsoft and Google are building massive facilities in Southern's territory. Georgia in particular has become a magnet for new semiconductor plants, electric vehicle factories, and tech campuses, all of which need enormous amounts of power. For the thesis to work, Southern needs to get rate increases approved by regulators, keep costs under control, and successfully bring new power generation online on time.
