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 the Colorado Public Utilities Commission (COPUC), Rule 3627, Tri-State files its 10-year transmission plan with the COPUC on a biennial basis each February 1.

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.

Transmission projects

Tri-State continues to invest in transmission infrastructure to ensure dependable power delivery to its 43 member cooperatives throughout its four-state service territory. The West’s vast power supply network is currently strained – improvements and expansion to the system are essential to enhancing regional power reliability.

Additional transmission facilities open the door to diverse energy resources that include renewable energy. The investments in additional lines support renewable energy projects by alleviating transmission constraints to make projects economically viable. Expanding Tri-State's transmission network facilitates the G&T's ongoing pursuit of additional renewable resources.
