AEP Transmission is a division of American Electric Power. AEP is one of the largest electric utilities in the United States, delivering electricity and custom energy solutions to nearly 5.4 million customers in 11 states.
AEP owns the nation’s largest electricity transmission system, a more than 40,000-mile network that includes more 765-kilovolt extra-high voltage transmission lines than all other U.S. transmission systems combined.
AEP’s utility units operate as AEP Ohio, AEP Texas, Appalachian Power (in Virginia and West Virginia), AEP Appalachian Power (in Tennessee), Indiana Michigan Power, Kentucky Power, Public Service Company of Oklahoma, and Southwestern Electric Power Company (in Arkansas, Louisiana and east Texas). AEP’s headquarters are in Columbus, Ohio.
AEP Transmission is actively investing in the future by creating the infrastructure needed for electric reliability and economic growth. We are rapidly growing and we are building part of the more than $60 billion in U.S. projects planned through 2024 – grid improvements to be completed by the members of the Edison Electric Institute (EEI), the trade association for U.S. investor-owned electric utilities. This growth is fueled by changes in the generation market and the need to build more reliability, redundancy and capacity into the transmission system. AEP works together with communities, renewable generation providers, regulators, transmission developers and other utilities to design and build energy solutions without borders.
