The Western Transmission Consortium, a member-owned entity dedicated to building interregional and interjurisdictional transmission infrastructure across the Western United States, announced its official launch on May 6.
With founding members representing eighty-four utilities across the eleven Western states, the launch of TWTC “is a significant milestone in the effort to develop a more resilient, coordinated, and future-ready electric grid that enhances reliability and enables greater integration of energy resources across the West,” it said.
A number of public power utilities are members of TWTC.
Structured to support collaborative development across the eleven Western states, TWTC has transitioned from its initial development company phase into its operational phase.
This transition comes as TWTC completes critical governance, budgetary, and project curation milestones.
As part of this progression, TWTC held a meeting on April 25, 2025, during which the Founding Members advanced discussions around project selection and alignment with state and federal planning goals.
The group will continue to move forward with due diligence on nine individual projects covering 1,100 miles across five Southwestern states.
TWTC will now move forward in June to identify and prioritize high-impact transmission projects in the Northwest.
