Each year, Tri-State develops a 10-year transmission plan that assesses future transmission needs for Tri-State’s 42 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.
