Company Overview
ATC was founded in 2001, as the first multi-state, transmission-only utility in the United States. Unlike most other utilities, we have a single focus: transmission. Our transmission system allows energy producers to transport electric power from where it’s generated to where it’s needed. It’s similar to the interstate highway system, with high-voltage electricity traveling on the transmission system wires like vehicles on the highway.

Vision, mission, culture and values

ATC has a defined vision, mission, culture statement and core values that we live and work by every day. They provide insight into who we are, and are essential to our culture and our efforts to provide value to our stakeholders. Our hiring process is designed to find new employees that will be successful within our organization. We are professionals who work hard and have fun, and we seek out individuals who will thrive in our challenging and exciting workplace.
