Xcel Energy is proposing to replace the 60-year-old Alamosa to Antonito 69-kilovolt (kV) transmission line in the San Luis Valley to increase electric reliability and reduce potential safety risks associated with aging poles and equipment.

The 39-mile line is critical to providing reliable service to customers and cannot be taken out of service to be replaced. For that reason, we need to build a new power line in the area, either in a new corridor adjacent to the existing line or in a separate corridor near the current location.

Xcel Energy is currently studying preliminary route options to relocate the existing line.

We held open houses in November 2021 to introduce the project and ask for feedback on potential route options. We continue to evaluate those comments and study routes we may eventually propose for development. If you’d like to provide feedback on potential routes, please email or call 1-855-839-8865.

Project Need

Due to natural weathering, lightning damage and unscheduled interruptions in service, the wood pole structures, equipment and components that were installed more than 60 years ago need to be replaced.

The new infrastructure will address aging poles and equipment to improve electric service to homes and businesses in Alamosa and Conejos counties.

Project Description

The existing 69 kV transmission line will be rebuilt. All structures and conductor wires will be removed and rebuilt with new fire-resistant steel structures, new conductors and new Optical Ground Wire (OPGW). The OPGW keeps our system smart by providing a communication channel to transport system performance data to aid in faster, more efficient response times if power is interrupted. The OPGW also aids as a grounding source for lightning during storms.

Public Outreach

Xcel Energy is committed to working with residents, landowners, officials, and other stakeholders to explain the need for the Project and to identify a route that minimizes impacts to the environment and communities while aligning with engineering and safety standards. Residents and landowners are encouraged to provide feedback by submitting a comment postmarked on or before March 24, 2022, for consideration during the routing study and local permitting process. You can also email us at or calling toll-free 1-855-839-8865.

Please take a few minutes to provide your comments or questions about the transmission project by filling out the public comment form. Thank you.
