Duke Energy Corporation

Duke Energy makes and sells electricity to millions of homes and businesses.

Duke Energy is a giant utility, which is a fancy word for a company that makes electricity and pipes it into your house. It serves about 8 million electric customers, mostly in the Carolinas, Florida, and the Midwest, plus around 1.6 million gas customers. You pay Duke every month whether you think about it or not, and that steady stream of payments is the whole point. Think of it as a toll booth on the road to your light switch — Duke built the road, maintains it, and collects a fee from nearly everyone who drives on it.

The business splits into two main pieces. One is Electric Utilities and Infrastructure, which is the overwhelming majority of revenue and profit, generating and delivering power to homes and businesses. The other is Gas Utilities and Infrastructure, a smaller slice that moves natural gas through pipes. Regulators decide how much Duke can charge and what profit it's allowed to earn, so it's not a wild free-for-all — it's more like a boring, reliable business that grows slowly and predictably. That's exactly why investors like it: it pays a solid dividend and doesn't swing wildly with the economy.

Lately Duke is spending heavily on the boring-but-huge stuff: upgrading the grid, building more solar and batteries, and shifting away from coal toward cleaner power. It's also still dealing with the aftermath of coal ash cleanup, which costs real money. Because utilities need constant cash for these giant projects, Duke reinvests most of its cash flow into the business and funds the rest with debt and new shares, while still paying shareholders a dependable dividend. It's not exciting, but it's essential — the kind of company that keeps the lights on and the money flowing.
