The US Army Corps of Engineers, Walla Walla District is seeking sources to Manufacture and Supply one new 230 kV spare single phase transformer at McNary Dam. McNary Dam replaced aging GSU transformers with new transformers designed, manufactured, and tested between 2004 and 2010. A critical spare initiative performed by HDC in 2012 indicated McNary Dam was the highest priority project in the Federal Columbia River Power System (FCRPS) to warrant purchase of a spare transformer.

The spare transformer must be the same configuration and impedance as the existing transformers. The work includes review of the existing design, manufacturing, shop testing, delivery, post-delivery testing, and installation for long term storage in an existing spare vault.

The spare transformer shall be a single-phase generator step-up (GSU) power transformer rated 40,000/53,333/66,667 kVA, 230 kV GrdY/132.8 kV high-voltage, 13.2 - 13.2 kV low-voltage, Class ONAN/ONAF/ONAF cooling.

Other requirements include, but are not limited to the following.
1. Identical H-X, H-Y, and X-Y percent impedances as the existing transformer within the tolerances specified by paragraph Tolerances for impedance of IEEE STD C57.12.00, 2015
2. Identical interface to the existing powerhouse annunciation, control and power connections
3. Connect to existing ISO phase bus duct with no modification to existing system
4. Identical locations of:
• Low-voltage bushings
• High-voltage bushings
• Neutral bushings
• De-energized tap changer
• Control panel
• COPS tank location
• Radiators and cooling fans
5. Overall similar electrical clearances to overhead conductors
6. Overall similar physical clearances to surrounding structures
7. Identical mounting as existing transformers including welded base with wheels and locking device
8. Identical high-voltage, low-voltage, and neutral bushings as the existing bushings.
9. Similar cooling fans and radiators that are interchangeable with the fans and radiators on the existing transformers
10. Similar quantity of oil as the existing transformers
