CCPG - Weld County Expansion Project

Public Service Company of Colorado (PSCo) invites your participation in the Tot 7 Expansion planning process.

The plan is expected to consist of new transmission originating at the existing Ault Substation in Weld County, Colorado, and connecting to the existing transmission system northeast of the Denver-metro area.

The project would increase local reliability to customers, especially in the Greeley, Colorado area, and provide transmission capacity to serve anticipated load growth in the region. The project may also accommodate additional generation resources north of Denver.

Since the project is expected to modify the existing Western Electricity Coordinating Council (WECC) Path 40 (Tot 7), PSCo is initiating the WECC Project Coordination Review and Project Rating Processes. The Colorado Coordinated Planning Group (CCPG) will be used in part as the forum for the processes.
