Please note per Amendment 01, the site visit was rescheduled for 05 May 2022. Your firm MUST RSVP to BOTH Karl Ahlen (karl.t.ahlen@usace.army.mil) AND Kristina Morrow (kristina.k.morrow@usace.army.mil) in order to attend. The U.S. Army Corps of Engineers, Portland District, has a requirement to replace a damaged section of metal-enclosed bus duct at the Lookout Point Dam. Power is delivered from three hydropower generating units to the Bonneville Power Administration (BPA) at 115kV through three Generator Step-Up (GSU) transformers located on the downstream deck of the powerhouse and a 115kV breaker in the BPA switchyard. In January 2020, the GSU transformer T2 experienced a differential trip during a switching operation of the 115kV breaker that then triggered the fire protection deluge system at transformer T2. This water infiltration resulted in a ground fault and damage to the metal-enclosed bus duct between the Unit #2 breaker and the transformer T2.
