Duke Energy Corporation
Duke Energy Corporation, through its subsidiaries, operates as an energy company in the United States. The company operates through two segments: Electric Utilities and Infrastructure (EU&I); and Gas Utilities and Infrastructure (GU&I). The EU&I segment generates, transmits, distributes, and sells electricity to customers in the Southeast and Midwest regions. It generates electricity through coal, hydroelectric, natural gas, oil, renewables, and nuclear fuel. This segment also engages in the wholesale of electricity to municipalities, electric cooperative utilities, and other load-serving entities. The GU&I segment distributes natural gas to customers in the residential, commercial, industrial, and power generation natural gas sectors; and invests in pipeline transmission projects, renewable natural gas projects, and natural gas storage facilities. The company was formerly known as Duke Energy Holding Corp. and changed its name to Duke Energy Corporation in April 2006. Duke Energy Corporation was founded in 1904 and is headquartered in Charlotte, North Carolina.
What does it do?
Duke Energy is one of the largest electric and gas utility companies in the United States, powering homes and businesses across six states — including North Carolina, South Carolina, Florida, Indiana, Ohio, and Kentucky. Think of it like the company that keeps your lights on and your heat running. It owns and operates power plants (using nuclear, natural gas, coal, and renewables), plus thousands of miles of power lines that deliver that electricity to roughly 8 million customers. It also distributes natural gas to about 1.6 million customers through a separate part of the business.
Utilities like Duke are getting a second look from investors right now because of the massive surge in electricity demand driven by AI data centers, electric vehicles, and the push to bring manufacturing back to the US — all of which need enormous amounts of power. Duke sits right in the middle of some of the fastest-growing regions in the country, particularly the Southeast, meaning it could see demand growth that utilities haven't experienced in decades. In a world of uncertainty, its regulated business model — where the government essentially guarantees it can earn a set return — makes it a rare source of predictable income.
How does it make money?
Duke makes money in a straightforward way: it charges customers for electricity and gas, and regulators (state governments) approve the rates it can charge, ensuring Duke earns a reliable profit. Its Electric Utilities and Infrastructure segment is by far the biggest piece, generating the bulk of its $32.2 billion in annual revenue — up from $30.4 billion the prior year, a 6% increase. The gas business adds a smaller but steady stream of income. Because regulators allow Duke to pass most cost increases on to customers, its revenue and profits are unusually stable compared to most companies.
Why do investors care?
The growth story for Duke comes down to one word: demand. AI data centers are being built at a record pace, and many are landing in Duke's service territory in the Carolinas and the Southeast. Duke has announced a multi-year capital investment plan of roughly $73 billion through 2028 to expand and upgrade its grid — and when regulated utilities invest in infrastructure, they are typically allowed to earn a guaranteed return on that spending, which directly grows their profits over time. For this to work out, Duke needs regulators to keep approving rate increases and new infrastructure spend, and electricity demand needs to keep rising as expected.
