Our History

Since our founding in 2003, ITC has:

  • Acquired and integrated three electrical transmission businesses as owner/operator
  • Pioneered a greenfield transmission-only utility, ITC Great Plains
  • Identified and facilitated critical regional transmission projects
  • Established a portfolio of actionable development projects
  • Partnered with local utilities on projects
  • Explored creative approaches to power grid modernization

We continue to pursue these strategies, all part of our vision toward a “Greater Grid. Greener Future.” Here are some milestones:
