Voltage: 115/230 kV line
Estimated cost: $65 million
Target in-service: 2020
The Northern Greeley Area Project will increase electric reliability and load-serving capability of the Xcel Energy electric transmission system in and around the Greeley area. The approximately 25 miles of new 115 kilovolt (kV) and 230 kV transmission lines will be a first step 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. The 44 kV voltage is no longer a standard industry voltage.
The Northern Greeley Project has been a part of the company’s long-range transmission plans since 2013 and has been presented and documented in numerous forums and reports, including annual Rule 3206 Reports and Rule 3627 Plans.
The plan aligns with the objectives of the SB100-07 statute by starting to establish transmission into a proven energy resource zone, which could provide future interconnection opportunities for wind resources in the area.
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 Greeley 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 other infrastructure. Those issues are determined through a separate local government siting process.
The Northern Greeley Area Transmission Project consists of the following components:
