About this file
This solicitation is for the replacement of station service (SU) and central quick-start (CQ) feederboards at the Bonneville Lock and Dam Powerhouse II located in Oregon. The U.S. Army Corps of Engineers seeks to replace aging 480V panels that are original equipment and whose components are no longer manufactured. Bonneville Dam provides hydropower and navigation on the Columbia River and Powerhouse II was completed in 1982 with eight main generating units for a total rated capacity of 612 MW. The SU and CQ panels were not included in recent station service work and their condition rating is now marginal, necessitating this replacement solicitation.
