The high side of the Power City substation north of Hermiston was expanded to allow for 115kV (kilovolt) transmission lines to flow in and out of the substation, tying into UEC’s existing 115kV facilities in the area. Power City is an existing distribution substation within UEC’s system that provides power to many members in Umatilla, Hermiston, and the surrounding areas. Originally built in 1999, the station has been providing reliable service for 23 years.
