Two 138 kV Substation Power Transformers with Installation and Commissioning

The City of Edmond Public Works Authority is seeking bids for outdoor substation power transformers and associated delivery, installation, and commissioning. - Buyer: City of Edmond Public Works Authority, City of Edmond, Oklahoma; no sub-agency or purchasing office is identified. - Transformer quantity and configuration: The technical specifications call for two outdoor, three-phase, mineral-oil-filled transformers rated 138 kV to 7.557/13.09 kV, with 15/20/25/28 MVA cooling ratings.

No transformer manufacturer is designated; bidders must identify the offered brand and catalog or part number. - Included work and requirements: The manufacturer is to deliver, unload, assemble, install, adjust, test, and commission the transformers, assist with initial service, and instruct purchaser personnel in operation and maintenance. The transformers and accessories require a five-year warranty. - Procurement submittals: Bidders must provide a completed equipment data form, address the material specifications and disclose exceptions, and provide three similar-project references and a non-collusion affidavit. - Term: This is a one-time equipment procurement.
