Project Update

Colorado’s Power Pathway construction underway on Segments 2 and 3

October 2023

Construction Activities Update

We have started construction activities for Segments 2 and 3 of Colorado’s Power Pathway, including Canal Crossing, Goose Creek and May Valley substations. For more information on current construction activities, visit our Construction page.

Permitting Activities Update

Land use permitting activities continue for Segments 1, 4 and 5 in Weld, Pueblo, Arapahoe, Elbert, El Paso and Lincoln counties. Approvals have been received in Morgan, Washington, Kit Carson, Cheyenne, Kiowa and Crowley counties for Segments 1, 2, 3 and 4 land use permits.

We have determined that a new substation, named Sandstone, will be developed along Segment 4 in northeastern Pueblo County. Segment 4 will continue to connect May Valley Substation in Kiowa County to Tundra Substation in Pueblo County.

We are proceeding with development activities for the May Valley – Longhorn Extension in Kiowa, Prowers and Baca counties and have identified the new Longhorn Substation site. Construction on the Extension and Longhorn Substation is anticipated to begin in 2025 and be completed in 2026, pending the Colorado Public Utility Commission’s final approval. Permitting for the May Valley – Longhorn Extension is anticipated to begin in 2024.

We encourage landowners to participate in the land use permit processes managed by the cities and counties that govern them. For more information on public hearings and the types of permits required, please visit our Permitting page.

Field Survey Activities Update

Land agents will continue to conduct outreach to landowners along the preferred transmission line route to answer questions, discuss and evaluate site-specific concerns, and discuss easements that may be needed. Construction crews are reviewing the transmission line route for factors that could affect construction methodology, such as access constraints.

Additional field crews are conducting environmental and cultural resource evaluations, land use surveys, and are assessing the condition of nearby infrastructure as part of required field survey work. These activities are being conducted in the public right-of-way and on private property where appropriate access rights of entry have been established.

Segment Status

The map reflects the location of the preferred transmission line route by segment, new substations and existing substations:

  • Blue outline – transmission line or substation permitted by jurisdiction, not yet under construction
  • Green outline – transmission line or substation under construction
  • Orange outline – transmission line or substation in permitting stage with jurisdiction
  • Solid dark and light red lines – Township and section boundaries (these are not transmission centerlines)

Additional revisions may be posted; please check back as this map will reflect the most up-to-date information.
