The AES Corporation
AES builds and runs power plants and sells the electricity to utilities, big industrial customers, and people in 15 countries.
AES is an electricity company, but it doesn't really work like the one that sends you a monthly bill. Instead, AES builds and operates power plants — huge batteries, solar farms, wind projects, and natural gas plants — and sells the electricity it produces to utilities, large factories, and other big buyers. It is essentially a merchant and operator of power: it finds places where electricity is needed, puts up the machinery, and earns money selling the output over long contracts.
The business has two main sides. The first is generation: AES owns and runs power plants around the world, mostly in the US, South America, and Asia. The second is a set of regulated utilities, where it runs the local grid and delivers power directly to homes and businesses. Owning the plant and selling the power is the core money-maker; the utility arm adds steady, predictable cash flow. That mix matters because the generation side is more exposed to power prices and fuel costs, while the utility side is closer to a boring-but-reliable toll road. The big story with AES today is that it is trying to turn itself into a leading builder of renewable energy and energy storage. It has been one of the largest developers of grid-scale batteries, which matter because solar and wind produce power only when the sun shines or the wind blows — batteries let that energy be stored and sold when people actually need it. AES also signed long-term deals with tech companies that need enormous amounts of electricity for data centers, which gives the company a fast-growing customer base alongside traditional utilities.
There are real risks. Building power plants is capital-hungry, so AES carries a lot of debt and must constantly raise money to fund projects. Power prices, interest rates, and the weather all affect how much money the plants make, and the company has had to pause some of its big plans when financing gets expensive. Competition comes from giant utility players and other developers, including NextEra Energy. The simple way to see AES: it is a company that builds the machines that make electricity, then collects payments for the power they produce.
