WAPA Ault to Cloverly Transmission Line
Voltage: 115/230 kV line
Estimated cost: $65 million
Target in-service: 2020
The Northern Colorado Area Plan will increase electric reliability and load-serving capability of the Xcel Energy electric transmission system in and around the Greeley area, and will provide accommodation for new generation resources in the region. The project will replace approximately 42 miles of the existing, lower voltage transmission lines with approximately 25 miles of new, higher voltage transmission.
The proposed Western Area Power Authority (WAPA) Ault to Cloverly Transmission Line includes approximately 25 miles of new 115 kilovolt (kV) and 230 kV transmission line, between the WAPA Ault Substation, located approximately five miles northwest of the town of Ault and the Cloverly Substation, located approximately one mile northeast of Greeley. The project also includes two new substations and one substation expansion.
The first phase of the project includes building approximately seven miles of 230 kV transmission line between the WAPA Ault Substation and a new substation near the town of Ault. Pending approvals, the entire project is expected to be completed by 2020.
Public Open House
A public open house was held in Ault on October 26 to serve as an opportunity for residents to learn more about the project, view potential route maps, ask questions and provide feedback on the project and potential routes. Another open house will be held in early 2018 for the remaining segments of the project.
Project Need and Benefit
The Northern Colorado Area Plan is part of an initiative to replace the existing 44 kV system in the area with higher voltage transmission facilities. The 44 kV system is one of the oldest transmission assets owned by Xcel Energy with some of the infrastructure dating back to the early 1900’s. Replacement of this lower voltage system will increase reliability and load serving capability in and around the area, and will provide accommodation for new generation resources in the region.
The Northern Greeley Plan has been a part of the company’s long-range transmission plans since 2013.
Xcel Energy filed a Certificate of Public Convenience and Necessity (CPCN) application with the Colorado Public Utilities Commission (CPUC) on March 9, 2017 to construct the Northern Colorado Area Plan. When proposing a high voltage transmission line project, investor-owned utilities must file a CPCN application with the CPUC. You can review all regulatory filings on the CPUC web site by entering 17A-0146E in the ‘Proceeding Number’ field. The CPCN process allows the Company to proceed with implementation, but does not decide the specific routes and locations of the transmission lines and substations. Those issues are determined through a separate local government siting process. Xcel Energy will file for development permit approvals with Weld County and the towns of Ault and Eaton in fall 2017.
