We are proposing Colorado’s Power Pathway Project. The approximately 560 miles of 345-kilovolt double-circuit transmission line in mostly rural counties will open new avenues for renewable energy resources to be built and delivered to customers, helping meet the state’s clean energy goals, and bringing low-cost electricity where it’s needed.
These rural counties are rich with renewable energy resource development potential, but do not currently have a network transmission system that can integrate new resources needed to meet the state’s clean energy goals.
This $1.7 billion proposal supports the company’s Clean Energy Plan that will add 5,500 megawatts of new generation, primarily renewables, to the grid and deliver by 2030 an estimated 85% reduction in carbon dioxide emissions from 2005 levels.
We have filed a Certificate of Public Convenience and Necessity with the Colorado Public Utilities Commission for a transmission line to be built between substations that span from the Front Range to areas of north central, eastern and southern Colorado. The most northern point will be at our existing Fort St. Vrain Substation in Platteville in western Weld County.
The Pathway Project will then span east to a new substation near Fort Morgan, then southeast to Cheyenne County near the Cheyenne Ridge Wind Project, south to Prowers County near Lamar, then west to Tundra Switching Station in Pueblo County. The project will then run north to its terminus at the Company’s existing Harvest Mile Substation, located southeast of Aurora in Arapahoe County. A segment from Prowers south to Baca County is also under consideration. The project also involves expansion of three existing substations, expansion of one planned but not yet in-service substation, and construction of three new substations.
The transmission expansion is proposed to be completed in stages, with the first segments in service by the end of 2025 and others following in 2026 and 2027. Construction would be sequenced and is planned to start in 2023.
The project requires approval from the Colorado Public Utilities Commission (CPUC) for a Certificate of Public Convenience and Necessity (CPCN). The Commission determines whether the project is needed and in the public interest. Xcel Energy's application with the CPUC can also be found by visiting the Public Utilities Commission web site at state.co.us and entering Proceeding No. 21A-0096E in the Search field. Visit the CPUC website to view regulatory documents associated with the project, including notices, filings, public comments and more.

Local land use permits may also be required for approval in the counties or municipalities where the project is located.
Your input is important. In the coming months, we will begin to conduct our routing and siting studies for the Pathway Project. As part of this effort, we will be conducting public outreach to gather input for routing and siting decisions. More information about outreach and contact information for the project team will be posted here in the near future.
