Pinnacle Peak Substation, AZ

Wilson performed above-grade electrical work for new 500kV and 230kV substations, including all associated wire and equipment. Work included rerouting existing 500kV and 230kV transmission lines in a heavily congested corridor to bypass or cut-in to new and existing yards owned by three different utility companies.

Wilson performed work under six circuits of existing energized 230kV lines with limited outages.
