JDA SPARE GSU BUSHING INSTALL AND TRANSFORMER TESTING

SYNOPSIS

The U.S. Army Corps of Engineers (USACE) Portland District is soliciting a contract for The John Day Lock and Dam Spare GSU Bushing Install and Transformer Testing in Goldendale, Washington. The proposed project will be a sole-source, firm-fixed price (FFP) contract.

Background: The existing spare Generator Step-Up (GSU) transformer has been stored at its current location on the intake deck of the John Day Lock & Dam since 1978 and is not currently operational. The spare GSU transformer does not have bushings, low-voltage bushing housing, radiators, fans, temperature indicators, and the control cabinet is missing some devices.

Currently, John Day Dam does not have an operational spare transformer should one of the in-service units fail which poses significant risk to the regions power needs. This testing contract is critical to understanding if the current ‘spare’ unit can be upgraded and availability for emergency service restored or if an entirely new transformer needs to be purchased. If a new transformer is required, the lead-time on that supply is 3-5 years.

The existing spare GSU transformer has been stored at its current location between GSU Transformer Banks T3 and T4 on the intake deck (elevation 281) since 1978.
Serial#            7000893
Rating            164MVA/218MVA
Oil Capacity   15539 Gal

The spare GSU transformer does not have the following components installed:
• High-voltage (HV) bushing
• HV neutral bushing
• Low-voltage (LV) bushings
• LV bushing housings
• Radiators
• Fans
• Temperature indicators

John Day Operating Project presently has a spare 500kV shell-form single phase Westinghouse (now owned by Hitachi) GSU
transformer located between GSU transformer banks T3 and T4 on the intake deck (EL. 281). The Project maintains a spare GSU
transformer onsite in the event of an existing transformer experiences failure. As part of the solicitation, the spare transformer will be
installed with Government furnished bushings and tested. In addition, the spare transformer will be furnished and installed with
bottom terminals for the Government-furnished high-voltage (HV) and low-voltage (LV) bushings and other ancillary materials. The
requested Hitachi bottom terminals for the HV, HV neutral, and LV bushings would be a direct replacement for the existing Hitachi
(previously, Westinghouse) bottom terminals on the spare GSU transformer at John Day Operating Project. The GSU system and its
drawings are proprietary to Hitachi. With the proprietary nature of the system, the installation of the materials and the associated
electrical testing must be performed by an authorized Hitachi Representative.

Purpose: The US Army Corps of Engineers – Portland District has a requirement to solicit non-personal services to include the install of government furnished bushings on a spare 500kV shell-form single-phase Westinghouse generator step-up (GSU) transformer and related electrical testing. This requirement also includes furnishing and installing bottom terminals for the government-furnished highvoltage and low-voltage bushings as well as other ancillary materials described herein. All work must be in accordance with the details provided in this Performance of Work Statement (PWS) and comply with all local, state, and federal regulations.
