Recently completed activities: Major site grading and the substation access drive.
Upcoming activities: Transmission line construction north from the substation site will begin in mid to late October. Initial ground-level work will include installation of erosion control measures, setting mats in wetland areas and pouring concrete foundations for transmission line structures.
Substation construction began in early 2021 and we anticipate completing the work by Summer 2022. Construction schedules may change. Please checkback for updated as work continues.

The new Avery Substation will add capacity to deliver reliable, safe electric power to a fast-growing area of Northern Colorado. Proactive planning for current and future growth will help reduce the risk of electric outages and improve grid reliability while meeting needs for years to come. The new Avery substation will serve homes and businessess in and around Windsor, Severance and Timnath. View benefits.
The Avery Substation Project includes several components:
We have worked with the community on this project since 2012. We invited over 1,700 landowners and stakeholders to attend the public open house on July 9, 2019. Attendees were asked for feedback on two potential sites for the substation and transmission line extension in Windsor, both on property owned by the City of Thornton. Since the public open house, we have identified the West Site, located northeast of the intersection of Weld County Road 76 and Latham Parkway in Windsor as the project location (PDF). We chose the West Site location because it offers a wide range of benefits and is the preferred site based on recent public feedback.
The Town of Windsor approved the Conditional Use Grant permit application for the West Site in November 2019. Additional details about the Town of Windsor Planning Commission and Town Board approvals can be found on the Town of Windsor website (external link).
The substation is located more than 1,500 feet away from adjacent subdivisions to reduce the visual scale of the facility.
The substation maximizes distance from wetlands near Lee Lake and near Weld County Road 76 that may support wildlife.
The substation uses existing vegetation, topography, and distance to reduce the visual impact of the facility and will also incorporate additional landscape screening in the site design.
The substation includes a straighter path for the transmission line and minimizes the number of large support structures, while increasing the distance of the transmission line from the majority of viewers.
The substation is consistent with the consensus of those attending and commenting on the project during the July 2019 public open house for the reasons outlined above.
