The Bureau of Reclamation is seeking contractors for the Grand Coulee Right Powerplant GSU Transformer Replacements project in Washington State, approximately 90 miles west of Spokane. The project involves replacing three in-service, single-phase Generator Step-Up (GSU) power transformers, with comprehensive requirements including manufacturing, testing, transportation, removal, and disposal of existing transformers. Key contract requirements include handling asbestos materials, installing seismic anchorage systems, modifying fire protection systems, and complying with Buy American provisions. Evaluation criteria will likely focus on contractors' capabilities, past performance on similar high-value projects (minimum $8M), transformer manufacturer details, and demonstrated expertise in power infrastructure replacements. The sources sought notice response deadline is February 11, 2025, at 5 PM Mountain Time, with an anticipated contract award in fiscal year 2026.

The contract is not set aside for any specific small business designation and falls under NAICS codes 237130 (Power and Communication Line Construction, $45M size standard) and 335311 (Transformer Manufacturing, 800-employee size standard). The estimated contract value exceeds $10 million, with the project requiring three new 50 MVA transformers featuring synthetic ester fluid insulation and specific voltage and temperature requirements. Contractors will need to demonstrate capabilities for comprehensive transformer replacement, including removing existing equipment, installing new infrastructure, and modifying electrical connections. The work will be performed at the Grand Coulee Dam, which can be accessed via a government-owned rail siding in Odair, Washington. The contract will likely be structured as a hybrid Firm Fixed Price arrangement for both construction and supply components.
