About this file
These documents contain technical reference drawings for generator step-up (GSU) transformers at the Fort Peck Dam in Montana, specifically for Switchyard #2, Units 4 and 5. The drawings provide detailed engineering specifications, including plan views, section views, connection diagrams, and dimensional layouts for two transformers manufactured by ELIN. The technical drawings cover electrical connection details, transformer configurations, terminal arrangements, and technical specifications such as voltage ratings (230 GND Y-13.8 Delta), transformer capacities (36000/48000 KVA), and various technical parameters for electrical components and control devices.
The drawings are part of a broader federal contract opportunity (Solicitation W9128F25RA053) for GSU transformer supply at Fort Peck and Oahe Dams, involving design, manufacturing, factory acceptance testing, delivery, and associated control components. The primary NAICS code is 335311 (Power, Distribution, and Specialty Transformer Manufacturing), with a small business size standard of 800 employees. The contract is being administered by the U.S. Army Corps of Engineers Omaha District, with site visits scheduled in May 2025 and solicitation documents available through SAM.gov.
