What the company or idea is
Entergy is a vertically integrated electric utility headquartered in New Orleans, formed in 1913 as Arkansas Power Company, renamed in 1989, and expanded via the 1994 merger with Gulf States Utilities.
How it actually makes money
Entergy makes money by generating and selling electricity to three million retail customers across Arkansas, Louisiana, Mississippi, and Texas.
What works
Its scale works: 24,000 MW of generating capacity, $11 billion in annual revenue, and service to three million customers confirm operational reach within its four-state footprint.
What does not
The material does not establish how Entergy funds its capital expenditures, what its profit margins are, how it prices power, or how it manages climate-related regulatory risk.
What to take from it
Entergy illustrates the persistence of regional, regulation-dependent utility models—built on century-old foundations, scaled through acquisition, and sustained by captive retail customers—not innovation or market expansion.
Is it worth your time
Yes—if you are studying how vertically integrated utilities operate in regulated southern US markets, or how legacy infrastructure companies consolidate through merger.
