Notice text
Detroit Dam and its Big Cliff downstream reregulating plant are located on the North Santiam River. Detroit's power generation comprises two units recently up rated to 70 MVA. Big Cliff contributes an additional 20 MVA from a single unit. Their combined 160 MVA feeds BPA's power grid via a pair of 87 MVA transformer banks located at the Detroit powerhouse. Each bank comprises three single phase 29 MVA units and is dedicated to its respective generator. Switchgear in the Detroit powerhouse allows routing of Big Cliff's power to either, but not both, of the two banks. The transformers have been in service 1953 (62 years).
Work will include the manufacturing and factory testing of two three-phase generator step-up (GSU) power transformers rated 87,000 kVA, 230 kV high-voltage (H), 13.2 kV low-voltage (X), Class ONAN cooling, for delivery f.o.b. Detroit Dam power plant. The transformer shipment, hauling, site reassembly, field testing, and coordination with a separate installations’ contractor are required.
