TRANSFORMER LOAD TAP CHANGER RETRO-FIT PROJECT

The Western Area Power Administration’s Desert Southwest Region is soliciting a turnkey retrofit of the legacy oil-type load tap changer on the McGraw Edison Power Transformer, Serial No. C-05324-5-1, located at the Headgate Rock Substation in La Paz County, Arizona. The project requires the replacement of the existing load tap changer with a new RMV-II-1320-15kV Vacuum LTC equipped with an integrated transition throat and the proprietary ETOS® MD-IV smart diagnostic platform from Reinhausen Manufacturing Inc., along with a reactor-type accessory set and ANSI-compliant control cabinet. The contractor must mobilize to the substation, perform pre-testing and final testing including Doble power factor, TTR, winding resistance, insulation resistance, and oil analysis, conduct internal inspections, install the new equipment via welding and cabinet replacement, complete a 48-hour vacuum process at 1 Torr or less with dew point testing under 1%, and deliver comprehensive documentation including as-built drawings, test results, and revised schematics. The work is to be completed within a 14-day continuous onsite period, and the contractor must submit an approved work schedule to the Contracting Officer and Contracting Officer’s Representative within 10 days of award. This solicitation is a total small business set aside under NAICS code 335311 for power transformer manufacturing, with a small business size standard of 800 employees, and is evaluated on a lowest price technically acceptable basis where technical acceptability serves as a pass/fail gate. All quotes must include the vendor’s SAM Unique Entity Identifier, be submitted electronically via FedConnect or email to reysewiltz@wapa.gov with the solicitation number in the subject line, and remain valid for 60 days beyond the closing date. Invoicing must be conducted through the U.S. Treasury’s Invoice Processing Platform, and contractors must comply with Federal, State, and OSHA safety standards including 29 CFR 1910, 1925, and 1926. Additional requirements include submission of crane inspection records and operator certifications if cranes are used, a 45-day advance notice for any foreign national personnel via WAPA Form 3000-72, adherence to anti-discrimination laws, and compliance with WAPA’s express warranty and consecutive numbering requirements.
