The Pacific Northwest Regional Office of the U.S. Bureau of Reclamation is conducting market research for a construction contract to supply and install six (6) 276 MVA, 45-degree rise, single-phase, outdoor, step-up transformers. Three (3) single-phase transformers will be connected on the high voltage side in wye and on the low voltage side in delta to create a three-phase connected bank.

Type: Single-phase, outdoor, GSU Transformer Capacity and Temp Rise: 165/220/276 MVA, 45-degrees C rise Frequency: 60-hz High Side: 310.687kV (538.125kV system) with 1675kV BIL Low Side: 15kV with 110kV BIL Impedance: 17.2% on a 276 MVA base Insulating Fluid: SYNTHETIC ESTER FLUID

Installation will occur over two different outage periods, one bank of three transformers per outage. The work will be located at the Nathaniel “Nat” Washington Power Plant (formerly named the Third Power Plant) at Grand Coulee Dam, adjacent to the Cities of Grand Coulee and Coulee Dam, Washington, approximately 90 miles west of Spokane, Washington, in Okanogan County.

The principal components of work will be:

1. Remove and dispose of three (3) GSU transformers from in-service operations.

2. Remove and dispose of four (4) GSU transformers from spare locations.

3. Remove and reinstall three (3) GSU transformers from in-service operation to spare.

4. Furnishing, installing, and commissioning two sets of three in-service generator step-up power transformers (total of six transformers).

5. Furnishing and installing new seismic anchorage systems for the new transformers.

6. Modify existing isolated phase bus for new transformers.

A DRAFT copy of the specifications is attached to this announcement, industry comments are welcome.

Drawings will be emailed to interested parties after receipt of a completed Federal Non-Disclosure Agreement (attached). Send completed NDA’s with a request for the drawings to the Contract Specialist Scott Cooper at smcooper@usbr.gov.

The estimated magnitude for this project is between $150 and $175 million.
