Palisades-Goshen Rebuild BPA’s Palisades-Goshen 115-kilovolt transmission line has gradually deteriorated due to exposure to the elements and normal wear and tear. BPA is proposing pole replacements and other upgrades to improve the line’s reliability and accommodate future load growth in the area. The line extends 52 miles from the Palisades Dam in eastern Idaho to BPA’s Goshen Substation south of Idaho Falls, Idaho. BPA proposes to replace the existing 115-kV wood poles with new 230-kV poles which will be about five feet taller. The new poles will allow the line to eventually operate at 161-kV and will prevent BPA crews from having to obtain a line outage when performing line maintenance. Schedule BPA completed a preliminary environmental assessment in April 2008 and will accept public comments on the document through May 9, 2008. BPA held public scoping meetings on May 30 and May 31, 2007, in Shelley and Irwin, Idaho and accepted comments through June 15, 2007. If BPA decides to proceed with this project, construction would begin in late spring 2008. Letters Comments Environmental documents Map
