Malta to Otero Transmission Line Rebuild

Project Overview

Xcel Energy is building a better, cleaner energy future by taking steps to create a smarter and stronger energy grid, for a more secure energy supply. This commitment includes replacing infrastructure reaching the end of its useful life.

We plan to replace the 50-year-old transmission line that runs from the Malta substation southward to the Otero tap, roughly adjacent to US-24 between Lake County Road 52 and Chaffee County Road 371.

The transmission line delivers critical energy between Colorado’s central mountain communities and the San Luis Valley. It was originally built with wood H-frames. Due to natural weathering and the overall age of the poles and equipment, the line is reaching the end of its useful life and must be replaced. The transmission line will be rebuilt to current industry standards that include additional measures to reduce wildfire risk. New infrastructure will improve electric service reliability to homes and businesses in the region and help meet the growing energy needs for years to come.

Project details

The majority of the 20-mile line crosses land owned by the Bureau of Land Management, U.S. Forest Service and state conservation easements within Chaffee and Lake counties. A small portion crosses private property. All work will be done in compliance with strict conservation requirements established by these public agencies.


The rebuild project will take approximately two years of construction work to complete and is dependent on weather. Crews will conduct survey work and planning in 2024 and will begin construction operations in 2025. Work will continue until fall and resume in 2026.
