American Electric Power
AEP, headquartered in Columbus, Ohio, is one of the largest electric utilities in the United States, delivering electricity to more than 5 million customers in 11 states. AEP ranks among the nation’s largest generators of electricity, owning nearly 38,000 megawatts of generating capacity in the U.S. AEP also owns the nation’s largest electricity transmission system, a nearly 39,000-mile network that includes more 765-kilovolt extra-high voltage transmission lines than all other U.S. transmission systems combined.

AEP is a leader in the development of transmission technology, and has been since the earliest days of its history. AEP energized the first long-distance transmission line in 1917. In 1969, AEP was the first company in the world to introduce 765-kilovolt (kV) transmission technology, the highest voltage used in the United States today. A history of cutting edge advances in technology, including development and installation of 765 kV transmission lines, the highest voltage, most-efficient transmission lines in the country, continues today. The latest 765 kV technologies use a new six-bundle configuration that cuts audible noise from the project to half that of earlier generations of 765 kV lines.
