Transmission Maintenance crews responded quickly and in force to restore electric service in southeast Colorado, northeast Colorado and southeast Wyoming after tornadoes damaged three of our transmission lines over a six-day period. Their dedication and skill, along with that of the Engineering and Construction department and Inventory Control department, ensured the resiliency of our transmission system after severe weather extensively damaged or destroyed 40 structures. 

Cooperatives like Big Horn are always looking for ways to better serve their member-owners. One way of doing that is by offering rebates for energy-efficient home and business upgrades.

Tri-State’s mission is to provide reliable, affordable and responsible energy to our members and that work includes planning ahead to avoid risks to our transmission system that can cause power outages.
