Transmission
Keeping the Energy Flowing
Making the connections that power tomorrow's possibilities drives us. With a commitment to safety and a long history of continuous innovation, we uniquely combine an in-depth knowledge of the current electrical system with an understanding of the marketplace and technologies that will make up the grid of the future.
We own the nation's largest electricity transmission system — 40,000-miles — with more 765-kilovolt extra-high voltage transmission lines than all other U.S. transmission systems combined. It brings high-voltage power from generation operations to substations, where it's "stepped down" to be used by numerous distribution networks.
Strengthening the Grid
We are investing significantly to update and strengthen the grid across its footprint. Watch this video to see what's driving the need for these improvements and how AEP Transmission is getting it done.
We use industry best practices to protect wetlands, waterways, habitats and endangered species, be it in the siting of new construction, the build itself, or site restoration activities.
