Pawnee-Daniels Park Project

Construction Update

  • Construction is underway on the 20-mile segment of the Pawnee-Daniels Park project in Aurora and Parker between the new Harvest Mile Substation and the Daniels Park Substation. View project area.
  • Crews have started foundation work east of I-25 and are moving south. Structure settling should begin in late April or early May. Site preparations are also taking place including inspections and material delivery. Crews are hauling materials, including steel structure sections to the project right-of-way near Daniels Park Substation in Douglas County.

Rebar cages are built offsite and delivered to the construction site to be used as part of the transmission foundation.

We want to thank you for patience during construction activities. It’s our mission to ensure your family, neighbors and construction crews stay safe each day. Please use caution when walking or driving near construction zones. The new transmission line will enable the electric grid to carry more renewable energy, improve overall system reliability and support the region’s economic growth.

Project Overview

The Pawnee-Daniels Park project includes the construction of 125 miles of 345 kilovolt (kV) double circuit transmission line between Pawnee Substation, near Brush, CO, and the Daniels Park Substation, south of the Denver-metro area, as well as one new 345kV substation and expansion of five other 230 kV and 345 kV substations. Construction is underway on portions of the project. The in-service date is October 2019.

Project Need

The project is required to facilitate future generation development (including Xcel Energy's Rush Creek Wind Generation Project). It will help support Resource Planning predictions for other generation development in the region, meets SB-100 requirements for Energy Resource Zones (ERZ) 1 and 2, and improve system reliability.

Regulatory and Permit Approvals

The Colorado Public Utilities Commission (CPUC) approved a Certificate of Public Convenience and Necessity application for the project on April 9, 2015.

The CPCN included an in-service date for the project of May 2022 with construction beginning in 2020. However, in late 2015, Congress extended the Production Tax Credit for new wind generation projects, but with a declining recovery schedule for projects that start construction after 2016. As a result of this, Xcel Energy filed with the CPUC asking them to modify their previous decision in order to accelerate the in-service date to October 2019 and the construction start date to January 2019 for the Harvest Mile-Daniels Park portion of the project. In September 2016 we, along with multiple parties, agreed to a settlement that included moving the in-service date to 2019. The settlement agreement received final approval October 2016. View the settlement agreementsAdvancing the in-service date of the Pawnee-Daniels Park project will help ensure that customers reap the tax credit benefits which significantly reduce the cost of wind generation.

Final local permits were approved for the projects in December, 2017. Permits were obtained with the City of Aurora, Arapahoe County, Douglas County and Town of Parker.
