How Southern Company Makes its Money: Revenue Breakdown
A breakdown of Southern Company (SO) financials. See how Southern Company makes money from Georgia Power, Alabama Power, Southern Company Gas, and more using their 2024 annual report.
How Does Southern Company Make its Money?
Southern Company is one of the largest electric utilities in the United States, serving approximately 9 million customers across the Southeast through its subsidiaries Georgia Power, Alabama Power, Mississippi Power, and Southern Company Gas. The company operates a diverse generation fleet including natural gas, nuclear, coal, solar, and wind. Southern Company’s Vogtle Units 3 and 4 in Georgia — the only new nuclear reactors built in the US in decades — achieved commercial operation, though the project went significantly over budget and behind schedule. The company is now well-positioned for data center demand growth in the Southeast.

Georgia Power — 44% of Revenue
Southern Company’s largest subsidiary and the leading electric utility in Georgia, serving 2.7 million customers across most of the state outside metro Atlanta’s municipal utilities. Revenue grew 8.7% in 2024, driven by strong load growth from data center development in the Atlanta-metro area and rate adjustments to recover capital investments. Georgia Power operates a diverse generation fleet including the newly operational Vogtle Units 3 and 4 nuclear reactors, natural gas combined-cycle plants, coal-fired generation (being retired), and growing solar capacity.
Georgia Power is the epicenter of Southern Company’s data center growth story. Georgia has become one of the largest data center markets in the US (metro Atlanta), and the demand for electricity from hyperscale data center operators (Google, Microsoft, Meta, Amazon) is accelerating — these facilities consume enormous amounts of power for servers, cooling, and AI workloads. Georgia Power’s ability to serve this demand with reliable baseload power (particularly the carbon-free nuclear generation from Vogtle) is a significant competitive advantage over utilities in regions with constrained generation capacity.
Alabama Power — 30% of Revenue
Southern Company’s second-largest subsidiary, the primary electric utility for the state of Alabama, serving 1.5 million customers. Revenue grew 8.5% in 2024. Alabama Power operates under a constructive regulatory environment and generates electricity from natural gas, coal, nuclear (Farley Nuclear Plant), and hydroelectric facilities. Like Georgia Power, Alabama is seeing growing industrial load from manufacturers and data centers attracted by reliable, low-cost power.
Southern Company Gas — 17% of Revenue
Southern Company’s natural gas distribution subsidiary, serving approximately 4.3 million customers across four states (Georgia, Illinois, Virginia, Tennessee) through Nicor Gas, Atlanta Gas Light, Virginia Natural Gas, and Chattanooga Gas. Revenue declined 4.4% in 2024, largely reflecting lower natural gas commodity prices passed through to customers (gas distribution utilities earn margins on delivery, not the commodity itself). Southern Company Gas provides revenue diversification and stable utility earnings that complement the electric utility subsidiaries.
Mississippi Power & Other Electric — 6% of Revenue
Mississippi Power serves customers in southeast Mississippi and is the smallest of Southern Company’s regulated electric utilities. Revenue grew 7.1% in 2024. This segment also includes other miscellaneous electric operations. Mississippi Power has a smaller customer base but operates under a similar regulated-return model.
Southern Power (Wholesale) — 7% of Revenue
Southern Company’s competitive wholesale generation subsidiary, which owns and operates natural gas, solar, and wind generation facilities that sell power to utilities and commercial customers under long-term power purchase agreements (PPAs). Revenue grew 5.9% in 2024. Southern Power has been a vehicle for Southern Company’s renewable energy expansion, building utility-scale solar farms across the Southeast and Southwest. Unlike the regulated utilities (which earn a guaranteed return), Southern Power operates in competitive wholesale markets — but long-term PPAs provide revenue visibility.

Southern Company (SO) Key Financial Metrics
- Gross Margin: 54.3%
- Operating Margin: 20.5%
- Revenue Growth: 5.8%
Is Southern Company Profitable?
Yes, Southern Company is consistently profitable as a regulated utility. The 54.3% gross margin reflects the pass-through nature of fuel costs — utilities recover fuel expenses from customers, and the gross margin represents the delivery and generation margin. The 20.5% operating margin is solid for a utility and reflects regulated returns on invested capital. Net income grew 10.3% to $4.3 billion, partly reflecting the completion of Vogtle Units 3 and 4 (which eliminates the earnings drag from construction-in-progress charges) and growing rate base across all utility subsidiaries. As a regulated utility, Southern Company’s profitability is fundamentally tied to the allowed return on equity (ROE) granted by state regulators — typically 10-11% — applied to the company’s growing rate base of generation, transmission, and distribution assets. The key to earnings growth is investing capital in assets that earn this regulated return.
Southern Company (SO): What to Watch
- Data center load growth in Georgia and Alabama — The Southeast is seeing explosive data center development, and Georgia Power’s territory (metro Atlanta) is one of the largest data center markets in the US. The pace of new data center connections and load additions could drive above-average electricity demand growth for years.
- Vogtle Units 3 and 4 nuclear performance — The Vogtle nuclear expansion (the only new nuclear reactors built in the US in decades) went massively over budget ($35B+) and years behind schedule. Now that both units are commercially operational, their performance (capacity factor, reliability, operating costs) is critical for Georgia Power’s earnings and for the nuclear industry’s credibility.
- Rate case outcomes and regulatory relationships — Southern Company’s earnings growth depends on regulators approving capital investments and allowing fair returns. Constructive regulatory environments in Georgia, Alabama, and the gas distribution states are essential.
- Renewable energy expansion — Southern Company is investing in solar and wind generation across its utility territories and through Southern Power. The pace and economics of the renewable buildout affect both the rate base growth and the company’s emissions reduction trajectory.
- Interest rate sensitivity — Utility stocks trade as bond proxies — when interest rates rise, utility valuations decline as investors can earn competitive yields from risk-free bonds. Southern Company’s 3.5-4% dividend yield is less attractive in a high-rate environment.
Southern Company (SO) Financial Summary
Southern Company is one of the largest US electric utilities, serving 9 million customers across the Southeast through Georgia Power (44% of revenue), Alabama Power (30%), Southern Company Gas (17%), and other subsidiaries. Revenue grew 5.8% to $25.4 billion in 2024, with Georgia Power (+8.7%) and Alabama Power (+8.5%) leading growth driven by data center demand and rate base expansion. The 20.5% operating margin is solid for a regulated utility, and net income grew 10.3% to $4.3 billion. The key growth catalysts are data center electricity demand in metro Atlanta (one of the largest US data center markets) and the earnings uplift from the newly operational Vogtle Units 3 and 4 nuclear reactors, which provide carbon-free baseload power increasingly valued by AI/data center customers.
