TRD GSU Transformer Replacements

The Department of the Interior Bureau of Reclamation is seeking a contractor to replace nine single-phase Generator Step-Up (GSU) transformers at three hydroelectric power plants located in California's Central Valley Project: Spring Creek, Judge Francis Carr, and Trinity Powerplant. The contract encompasses the full scope of transformer replacement services, including removal of existing electrical equipment, supply and installation of new transformers, anchorage work, and associated electrical infrastructure modifications. Key requirements mandate that the transformers be filled with synthetic ester insulating fluid, feature standardized connection heights, and be designed with the capability to be installed at any of the three plant locations. Evaluation criteria will assess technical approach, transformer performance specifications, manufacturing facility details, transportation logistics, company experience, and past performance. The proposal due date is October 31, 2025, at 0900 PDT, with proposal validity extended to 120 calendar days. Offerors must acknowledge receipt of all amendments prior to the proposal submission deadline to avoid potential rejection. The solicitation includes multiple amendments addressing site visit questions, specification clarifications, economic price adjustment provisions, and electronic submission procedures via Kiteworks.

This is an unrestricted procurement with no small business set-aside designation, issued under NAICS Code 237130 (Power and Communication Line and Related Structures Construction) and PSC Code Z2MD (Repair or Alteration of EPG Facilities - Hydro). The estimated contract value ranges from $35,000,000 to $50,000,000, with the contract period spanning 2,900 calendar days from the notice to proceed. No incumbent contractor is identified in the solicitation materials. The contract will be awarded on a firm-fixed price basis with provisions for economic price adjustment related to labor and material costs. The contractor must submit a small business subcontracting plan with negotiated subcontracting goals across various small business categories. The anticipated notice to proceed date is January 28, 2026, and all work performance will occur at the three identified California power plant locations within the Bureau of Reclamation's Central Valley Project.
