Publicly Traded Large-Cap Electric Utilities

U.S. Exchanges

List of Publicly Traded Large-Cap Electric Utilities Listed on Major U.S. Exchanges

The companies on this list are large-cap utilities that provide electricity service to tens of millions of customers throughout the United States. Through their subsidiaries, most of these companies offer their service to a specific region or a state but there are examples like The AES Corporation who are global service providers. It is common for these companies to have between 17,000 and 35,000 megawatts of generating capacity. It should be noted some of the larger companies exceed that capacity and some of the smaller state-focused companies fall below that range.

The means in which companies generate their power is quite diverse, even within the same company. It is not uncommon for the same company to generate power from more than one source which can include biomass, fossil, hydro, natural gas, solar, wind and nuclear sources.
