Avery Substation Project

Avery Substation Project

Estimated Length: 1.5 miles
Voltage: 230 kV
Estimated Cost: $14.8 million
Estimated In-service Date: Spring 2020

A public open house is scheduled for July 9.  View details below.

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.

The Avery Substation Project includes several components:

  • A new electric distribution substation located in the Town of Windsor
  • Overhead double-circuit 230,000-kilovolt (kV) electric transmission line (0.5 miles in unincorporated Weld County, 0.4 miles in Town of Severance and 0.5 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 1.5 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. To meet the growing needs of this region, construction of the substation needs to start by the end of 2019.

Please Join Us at a Public Open House for an Update

Xcel Energy invites you to attend a public open house to update the community on our proposed Avery Substation Project prior to submittal of the Conditional Use Grant application to the Town of Windsor later in July, 2019. We have reviewed public comments and other feedback about the proposed substation location and will be sharing information about modifications to the proposed substation location on Thornton-owned land at the northeast corner of Weld County Road 76 and Latham Parkway. Landscape screening options and concerns about wetlands and wildlife will be discussed.
