UNS Electric, Inc., (UNSE), a UniSource Energy Services subsidiary, on March 16 filed with the Arizona Corporation Commission an application for a certificate of environmental compatibility to build the Golden Valley 230-kV Transmission Line Project in Mohave County, Ariz.
The line, which would be located within and near Kingman and Golden Valley in Arizona, is designed to improve service reliability by replacing aging equipment and providing greater electric capacity to accommodate a projected increase in peak energy demand over the next decade in the north Golden Valley and surrounding areas, the company said.
The existing 69-kV transmission system is not equipped to serve future energy demands in the northern area of UNSE’s service territory in Mohave County, the company said.
The line would total about 17 miles to 18 miles in length, depending on the alternative approved, the company said, noting that while all portions of the line would be designed to accommodate double-circuit 230-kV transmission, portions would be built as either single-circuit 230-kV transmission, double-circuit 230-kV transmission, or double-circuit 230/69-kV transmission. In the areas where the structures are built as double-circuit 230/69-kV transmission, the existing 69-kV line would be removed or topped to allow for existing distribution and/or communication facilities to remain in place.
Noting that it, in conjunction with the Bureau of Land Management (BLM), has considered six alternative routes for the project, UNSE said that its preferred route — E1 East Cerbat Alternative — aligns with the BLM’s preferred route for the project.To read the complete article, visit TransmissionHub.
