Pintail Interconnection

115-Kilovolt Transmission Project

Xcel Energy proposes to build a new 115-kilovolt (kV) electric transmission line on steel monopoles from the existing Anadarko Substation to connect and supply the power to operate the proposed Phillips 66 Pintail Compressor Station, approximately 2.5 miles east of the Town of Gilcrest in Weld County, Colorado. The new proposed compressor station is needed to support the increased gas volumes forecasted by local gas producers in 2025. It is being designed with 30,000 hp of electric motor-driven compression that will transport the gas to local processing facilities. Phillips 66 requested the transmission interconnection and will fund its development.

We are evaluating three route alternatives for the transmission line (ranging from 2.5 to 3.5 miles) in a routing study that considers existing and planned land uses, proximity to residences, sensitive plant and wildlife species and their habitats, cultural resources, aesthetics/visual resources, and input received from landowners. Route Alternative 1 was selected as the preferred route.

Xcel Energy’s Pintail Interconnection Project and Phillip 66’s Pintail Compressor Station will be built and permitted separately; however, Xcel Energy and Phillips 66 are coordinating efforts.
