Thornton Substation Project

The Thornton Substation Project
The City of Thornton has experienced rapid development over the past decade with the addition of new retail, commercial centers and residential communities. To support this growth, meet customers’ needs for reliable power and continue to strengthen the local economy, Xcel Energy is working with residents to build the first substation in Thornton since 1992. It will provide the much-needed power to sustain and serve the community for future generations.

Project Purpose
As the area continues to grow, so do the energy demands of the community. Without this new substation, Thornton residents and businesses are at high risk for service interruptions, like the one experienced in 2012 which lasted over five hours. The new substation will provide the reliable power that residents and business owners can depend on.

Construction Details
Xcel Energy has spent numerous hours in the community gathering input and feedback. We have taken— and will continue to take—residents’ concerns into account in a final construction design, such as undergrounding the power lines into and out of the substation, as well as  incorporating an architectural wall and landscaping to match neighborhood aesthetics.

Proposed Schedule
Xcel Energy filed an application for a Certificate of Public Convenience and Necessity (CPCN) for the Thornton Substation, which was granted by the Colorado Public Utilities Commission in April 2015. In 2015 and 2016 we met with members of the community to develop a substation design suitable for the community. In October 2016, Xcel Energy filed applications for local government approvals to build the project. If approved, Xcel Energy expects to start construction early in 2017 and have the substation in service in 2018.
