Lake City Unplanned Outage

An unplanned power outage affected the Lake City and Powderhorn areas on Wednesday, August 18, 2021, during Tri-State Generation & Transmission maintenance along the main transmission line into Lake City along Hwy 149.

The purpose of the maintenance was to provide vegetation management, which helps ensure reliability of the transmission line in the Lake City area. Vegetation management activities include tree trimming within the right-of-way that helps protect the transmission line from damage from branches, falling trees, and wildfire.

At 8:57 a.m., equipment operated by a Tri-State contractor made contact with a guy wire that helps support one of the transmission structures. This contact caused the transmission line to trip and power was interrupted.

Tri-State transmission crews inspected the affected structure and the transmission line to determine that the line could be safely restored. In coordination with GCEA, Tri-State reenergized the line at 11:19 a.m.

“With this type of an outage on our transmission system, our Tri-State crews help ensure the safety of the public by thoroughly inspecting the system before a line is reenergized,” said Lee Boughey, VP Communications at Tri-State. “We appreciate GCEA members’ patience and understanding as we worked to safely restore power.”
