Keeping the Energy Flowing

We are dedicated to making the connections that power tomorrow's possibilities. 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 — more than 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.

The Power of the Grid

It's the largest machine in the world, and yet few of us know much about the electric transmission grid that makes life possible. "The Power of the Grid" introduces you to what it is, what it does and what's ahead for this critical infrastructure.

Investing in Transmission

The trends transforming and affecting the electric grid require investment in strengthening and expanding the AEP transmission system. These upgrades keep reliable, affordable electricity flowing to customers who rely upon it every hour of every day.

Why invest?

Building for Tomorrow, Together

Together, we can pool expertise and resources to tackle the challenges of transmission projects throughout North America and bring increased capacity and reliability to the grid.
