Pawnee-Daniels Park 345-kV Transmission Project

This proposed project consists of approximately 124 miles of 345-kV transmission from Public Service Company of Colorado’s (PSCo) Pawnee Substation in northeastern Colorado to its Daniels Park Substation south of the Denver metro area.

The first 95 miles of the project would expand the planned Pawnee-Smoky Hill 345-kV transmission line so there is a double-circuit, 345-kV transmission line between Pawnee and Smoky Hill substations. One circuit would be the Pawnee-Smoky Hill 345-kV line, and the second circuit would be one section of the Pawnee-Daniels Park 345-kV line.

For the remaining 29 miles between PSCo’s Smoky Hill and Daniels Park substations, new double-circuit, 345-kV transmission line would be constructed. One of the two circuits would be the second portion of the Pawnee-Daniels Park 345-kV line. The second circuit would create a new 345-kV transmission line between PSCo’s Smoky Hill and Daniels Park substations.

This proposed project is expected to accommodate approximately 300-500 megawatts of resources, interconnecting at or near the Pawnee Substation.
