Why we do it better

Collaborative partners

We believe there is no one-size-fits-all approach to transmission development. Instead, we prefer a collaborative approach to provide value to our partners by understanding their needs, challenges, opportunities and goals.

Investing in our partners’ success 

Year after year, ATC customer service surveys show that if given a choice in transmission builders, we are the preferred choice. Our mission is to enhance our partners’ ability to deliver energy, interconnect resources and access the wholesale energy market – cost effectively, reliably and safely. Our focus on collaboration allows us to add value, apply industry leading resources and share best practices with our partners.

We are among the top utilities nationally for transmission line construction, we are considered among the top transmission providers for reliability, and we have a reputation for superior customer service.

Diversity, strength in ownership

Our owners include investor-owned utilities, municipalities, municipal electric companies and cooperative utilities.

  • Strength in ownership numbers eases burden of compliance for all
  • Projects are studied to solve multiple system issues
