Business Model
What each company does and how it makes money
Public Service Enterprise Group is a regulated utility holding company operating primarily in the Northeastern and Mid-Atlantic United States. It generates revenue through its two main segments: PSE&G (regulated electric and gas distribution, ~70% of earnings) and PSEG Power (competitive power generation and wholesale energy marketing, ~30%). The company's primary moat comes from its regulated utility operations which provide stable, predictable returns through government-approved rate structures.
Ameren is a regulated electric and natural gas utility serving customers in Missouri and Illinois through rate-regulated generation, transmission, and distribution operations. It earns revenue primarily from regulated electric service (roughly 80% of total) and natural gas distribution, with rates set by state commissions that allow recovery of costs plus a reasonable return. Its key advantage is its regulated monopoly status in its service territories, providing stable cash flows through cost-of-service ratemaking.
