Replacing and maintaining aging infrastructure is important for the power industry to continue to deliver reliable and resilient power. Xcel Energy recently replaced and repaired some transmission and distribution structures near Glenwood Springs, Colorado, on the side of a steep canyon above the heavily trafficked I-70 corridor.
The transmission and distribution poles are part of the state power grid, which consists of hundreds of miles of high-voltage transmission lines that run across the State of Colorado. The pole replacement work would take place on the 6584 Shoshone-Glenwood Springs 69kV transmission line, which runs between the Shoshone Hydroelectric Plant – built in 1906 – and the Glenwood Springs Substation. Work would also be performed on the distribution-owned lines, including some distribution under-build as part of the circuit 6584 pole replacement work occurring between the plant and the Grizzly Creek Rest Area in Glenwood Canyon.
Many of the transmission structures had reached their end-of-life, with some dating back to their initial placement in the early 1900s.
The rebuild meant removing the existing wood structures, insulators and hardware, and installing new monopole wood structures, insulators and hardware. This work would be critical to allow Xcel Energy to continue to deliver reliable power to Western Colorado – today, tomorrow, and well into the future.
