Avery Substation Project

Avery Substation Project

Project update: The Town of Windsor approved the Conditional Use Grant permit application for the Avery Substation in November 2019.The substation is proposed to be located northeast of the intersection of Weld County Road 76 and Latham Parkway in Windsor. View approved site location. Xcel Energy is continuing to work with the Town of Windsor for other approvals, including the Administrative Site Plan and Minor Subdivision applications. Pending permit approvals, construction on the substation will begin in the spring of 2020. Please check back for updates. Xcel Energy will be in contact with surrounding landowners prior to start of construction.

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 while meeting the energy needs of existing and new homes and businesses for years to come. The new Avery substation will help improve grid reliability in Windsor and the surrounding communities as our existing Cobb Lake and Windsor Substations approach capacity. View benefits.

Project Location Chosen

We have worked with the community on this project since 2012. We invited over 1,700 landowners and stakeholders to our most recent public open house on July 9. Attendees were asked for feedback on two potential sites for the proposed 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 proposed location. 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).

Proposed West Site information

Distance

The proposed site is located more than 1,500 feet away from adjacent subdivisions to reduce the visual scale of the facility.

Wetlands and wildlife

The proposed site maximizes distance from wetlands near Lee Lake and near Weld County Road 76 that may support wildlife.

Screening

The proposed site 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.

View simulations

Transmission line

The proposed site 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.

Community preferred

The proposed site 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.

Project Overview

The Avery Substation Project includes several components:

  • A new electric distribution substation located in the Town of Windsor
  • Overhead double-circuit 230-kilovolt (kV) electric transmission line (0.5 miles in unincorporated Weld County, 0.4 miles in Town of Severance and 0.4 miles in Town of Windsor)
  • New distribution lines and upgrades to existing distribution lines near the towns of Windsor, Severance, and Timnath, Colorado.

Power for the proposed 1.3 mile 230-kV transmission line will be provided by interconnecting with the existing Platte River Power Authority (PRPA) Timberline-Ault 230-kV transmission line. This connection will supply the proposed Avery Substation with the electrical supply needed to power the distribution feeders serving the surrounding communities.
