Ostrander Substation Addition
CX(s) Applied: B4.11
Location(s): Clackamas County, Oregon
Office(s): Bonneville Power Administration
Bonneville Power Administration (BPA) is proposing to expand its existing Ostrander Substation near Barton, Oregon by approximately 4 acres. The expansion would accommodate three new 230/500 kilovolt (kV) transformers, with provisions for a spare transformer. The expansion of the substation is needed to replace aging infrastructure at the nearby McLaughlin Substation. BPA is proposing to replace the transformers at the Ostrander substation and lease the McLaughlin Substation. The proximity of the west side of the Ostrander Substation would allow connection of the new transformers and associated equipment to the existing McLaughlin-Ostrander 500-kV transmission line. The new transformers at Ostrander Substation would step down the voltage between the Ostrander and McLaughlin substations from 500-kV to 230-kV.
