AEP Transmission

What AEP Transmission does

AEP Transmission LLC is a regulated, transmission-only subsidiary of American Electric Power Company, Inc. (NASDAQ: AEP), headquartered in Columbus, Ohio, with operations spanning 11 states—Arkansas, Indiana, Kentucky, Louisiana, Michigan, Ohio, Oklahoma, Tennessee, Texas, Virginia, and West Virginia—and a workforce of 10,000+ employees. The company designs, constructs, and maintains high-voltage electric transmission infrastructure, including 345-kV, 138-kV, and 69-kV transmission lines, substations, steel pole and lattice tower structures, and reconductoring projects. It also delivers property-owner coordination services (rights-of-way, easements, line locations, access roads, agricultural operations support) and environmental stewardship programs (habitat conservation, bird collision prevention, construction clearing), supported by advanced field-survey technologies including LiDAR, ground penetrating radar, and unmanned aerial vehicle inspections.

The company's primary customer base is its parent company's regulated operating utilities—SWEPCO, AEP Texas, Appalachian Power, Public Service Company of Oklahoma (PSO), Indiana Michigan Power, and Kentucky Power—serving a combined end-customer base exceeding 5 million across multiple states. Revenue is generated through FERC-regulated transmission tariffs and state utility commission rate cases, recovering invested capital plus a regulated return on equity under cost-of-service frameworks. Long-term contracted capacity agreements with affiliate operating companies anchor demand, while regional transmission organizations such as the Southwest Power Pool (SPP) mandate incremental reliability projects.

AEP Transmission's flagship growth initiative is the Power Ready Grid program—a multi-billion-dollar rebuilding and reconductoring effort targeting approximately 5,000 miles of aging transmission lines across five states, supported by a $1.6 billion DOE-guaranteed term loan closed on October 15, 2025—the first financing to close under the new Energy Dominance Financing program. The modernization is explicitly oriented toward serving rising electricity demand from data centers and AI workloads, and is expected to support approximately 1,100 construction jobs while delivering infrastructure upgrades such as doubling voltage capacity on key corridors from 69kV to 138kV.
