Lehi Power Carter Substation Transformers RFP

Lehi City Corporation Power Department is conducting a Request for Proposal (RFP) to procure two three-phase power transformers for the Glen Carter Substation located in Lehi, Utah. The procurement seeks a qualified supplier to design, fabricate, inspect, test, deliver, dress, and fill transformers rated at 138-12.47kV with 13.2kV nominal low voltage, specifically engineered for operation at 4,600 feet above sea level. Bidders must submit comprehensive proposals electronically through the Bonfire website, with questions due by December 4, 2025, at 5:00 PM MST, and final proposals due by December 11, 2025, at 5:00 PM MST. Respondents are required to provide a detailed letter of transmittal, identify key project team members, submit client references, provide a transformer availability timeline, and furnish current financial reports. Evaluation criteria will include relevant qualifications, professional reputation, quality of goods and services, financial resources, litigation history, schedule availability, future maintenance capabilities, and proposed pricing. The transformers are expected to be installed in May 2029, with the City reserving the right to reject any proposals and negotiate contract terms.

There are no specific set-aside designations or restrictions on participating organizations mentioned in the documentation. The RFP requires that all transformers must be manufactured and assembled in the United States of America and carry a five-year warranty from final acceptance. While no incumbent vendors are identified, the specification mandates extensive technical compliance with ANSI, NEMA, NFPA, and ASTM standards. The transformers will require integration with existing substation infrastructure at the Carter Substation. Although a precise award value is not specified, the procurement includes detailed pricing mechanisms, such as loss evaluation methodology where guaranteed losses exceeding specified values will result in cost deductions. Bidders must provide pricing on a per-unit basis for two transformers, including field service engineering, technician costs, spare bushings, and potential additional service days. The comprehensive specification suggests a potentially significant investment in critical electrical infrastructure for Lehi City's power distribution system.
