USA, Colorado: Tri-State Generation and Transmission Association has completed and energized its 230 kV Burlington-Lamar transmission line in Colorado, which along with other projects under construction, increases reliability for Tri-State’s member distribution cooperatives, and provides for additional generation interconnection of more than 700 MW. Tri-State began construction on the line and improvements to its Burlington and Lamar substations in February 2024.
The line was energized last Friday. It is 112 miles long and is one of several major Tri-State transmission projects that will continue to be built into 2028. The projects under the Eastern Colorado Transmission Expansion, when completed, will have significant benefits for Tri-State’s interconnected transmission system, and bolster reliability for members.
As with almost all permitting and construction of major transmission line projects, the Burlington-Lamar project was years in the making. The company first proposed the expansion project in the early 2000s, examined the proposal again in 2016, and began development in 2020.
The line required permits, including some public hearings, from more than a dozen local, state, and federal government agencies or business entities. About 95% of the line was developed on private land, and crosses more than 100 parcels of land, requiring more than 700 signatures for access, options to acquire right-of-way, compensation, encroachment, and acquisition of right-of-way easements.
