Edison Electric Institute Membership
The Edison Electric Institute (EEI) serves as a primary organization for investor-owned utility companies. These entities are predominantly publicly-traded corporations responsible for the critical infrastructure required to supply power and electricity to both residential consumers and commercial businesses.
As of January 2026, the EEI maintains a comprehensive directory of its membership, which includes full members, Strategic Partners, and Associate Members.

Understanding the Membership Hierarchy
To accurately interpret the EEI membership list, it is essential to understand the distinction between holding companies and operating utilities. In the EEI directory, companies listed without an asterisk are parent or holding companies. These are the overarching corporate entities that own and manage one or more utility providers.
Conversely, companies marked with an asterisk are regulated operating utilities. These are the actual entities that manage the grid and deliver power to customers, operating under the ownership of the parent company listed directly above them.
Major Utility Groups and Their Subsidiaries
The membership spans a vast array of regional providers. For example, large holding companies like American Electric Power oversee multiple operating utilities, including AEP Ohio, AEP Texas, and the Appalachian Power Company. Similarly, Exelon Corporation manages several key providers such as ComEd, PECO, and BGE.
Other significant members include Duke Energy, Southern Company (which oversees Georgia Power and Alabama Power), and NextEra Energy, which includes Florida Power & Light Company.
