Project
Garver designed a 4.6-mile 69kV transmission line along the City of Siloam Springs' north and east boundaries. This line adds electrical capacity for a 20-year projected city growth. Garver's design incorporated several owner-requested enhancements, including galvanized steel poles and high temperature aluminum conductor steel supported (ACSS) transmission lines to provide standby capacity required for long-range planning.

The line starts near the Oklahoma / Arkansas state line at an interconnection point with Siloam Spring's power provider, Grand River Dam Authority. The line runs approximately 2.8 miles east to the location of a new proposed substation site and then turns south 1.8 miles to tie into an existing 69kV transmission line, thus completing a 69kV loop around the city. The transmission line has capacity for one medium voltage under-build over most of its length.

By working closely with the city, Garver provided a design that meets the special needs and desires of its client.
