Bonneville Power Administration is proposing to expand Forest Grove Substation located in Washington County, Oregon. The purpose of this project is to improve load service and reliability within the Portland vicinity as per the North American Electric Reliability Corporation reliability standards. Within the existing Forest Grove Substation, the switchyard fence line would be expanded to the north to make room for a new bay. Additionally, structure 12/1 of the Keeler-Tillamook #1 transmission line would be relocated approximately 10-feet ahead online in order to provide sufficient room to string a new conductor into the substation. If necessary, a tree may be removed from the Northeastern corner of the substation property to make room for a new access road along north perimeter of the substation property.
