Transmission planning

Transmission planning

Each year, Tri-State develops a 10-year transmission plan that assesses future transmission needs for Tri-State’s 43 member electric cooperatives. The transmission component of this plan is developed in conjunction with West Connect and the Colorado Coordinated Planning Group (CCPG), formal regional transmission planning organizations recognized by the Western Electricity Coordinating Council (WECC).

As part of a new requirement of the Colorado Public Utilities Commission (COPUC), called Rule 3627, Tri-State filed its 10-year transmission plan with the COPUC on February 1, 2014.

For more information, to send us your questions or comments regarding our transmission plans, or to be added to the stakeholder outreach list for future transmission planning meetings, please email TransmissionPlanning@tristategt.org.
