Colorado regulators approve Public Service Company of Colorado’s distribution substation

The Colorado Public Utilities Commission recently granted, without a hearing, an application by Xcel Energy’s (NYSE:XEL) Public Service Company of Colorado for a certificate of public convenience and necessity (CPCN) for the construction of the Titan Distribution Substation Project.

As noted in the decision, which has a mailed date of June 8, the project will be built in the Sterling Ranch area of Douglas County, Colo. The substation will be built immediately adjacent to the existing Waterton substation and will not require the construction of new transmission lines, but it will require the construction of short transmission tap lines from the existing transmission line into the proposed substation, the commission said.

The substation will be energized by building a 200-foot segment of 230-kV transmission tap line, which will interconnect with the company’s nearby 230-kV Daniels Park-Waterton transmission line.

The commission also said that the project’s estimated total cost, not including land costs, is $19.9m, and that the company is not requesting accounting treatment of the project costs.

Construction on the project is scheduled to begin in early 2021, and the facility is expected to be in service by the end of 2022, the commission said.

The application, which was filed in late March, was not contested, the commission said, adding that the company requests approval of the CPCN to serve about 55 MVA of new load growth from the Sterling Ranch and Shea Home residential developments in Douglas County, and to address reliability concerns in the area by providing backup and load transfer capability to the nearby Martin, Marcy, and Santa Fe substations.

Additionally, the project would position the company to serve a proposed expansion of the Lockheed Martin Aerospace Waterton Canyon campus, although the company did not have a specific load projection for that facility at the time that the application was filed.

The commission also said that the project will be adjacent to land that is mixed zoning, including land that is zoned for agricultural and open space conservation issues. The company has indicated that the nearest residential structure is more than 900 feet away, and that a wall can be built around the substation for noise mitigation, should noise become an issue, the commission said.

Among other things, the commission said that it “finds that the proposed project is needed to satisfy load growth and reliability requirements.”
