About this file
This document package includes engineering drawings and specifications for a federal contract opportunity to replace aging switchgear units and control panels at Bonneville Lock and Dam Powerhouse II in Oregon. The solicitation is being conducted by the U.S. Army Corps of Engineers Portland District on behalf of the Department of the Army. The project scope involves replacing the original 480V switchgear units and control panels in Powerhouse II, which are no longer supported due to being end-of-life components. Powerhouse II was completed in 1982 and the switchgear and control panels slated for replacement are the original equipment installed at that time. Replacing these critical electrical distribution components will improve reliability of power distribution to the hydropower generating units at Bonneville Dam Powerhouse II.
