Various Size Single Phase Polemount & Single & Three Phase Padmount Transformers

The City of Colton Electric Utility Department is seeking bids for various transformers, including single-phase polemount and single and three-phase padmount transformers. The procurement encompasses multiple transformer sizes and specifications, such as 50 KVA standard pole mount, 37.5 KVA and 50 KVA CSP pole mount, 75 KVA standard pole mount, 100 KVA and 167 KVA low profile padmount, 500 KVA and 750 KVA normal profile padmount, and 1500 KVA normal profile padmount transformers. All transformers must comply with NEMA & ANSI standards and have specific voltage requirements, primarily 12470 Delta primary voltage with various secondary voltage options. The bid evaluation will be based on firm price (FOB delivered to the Electric Yard), delivery time, and the cost of guaranteed average transformer losses. Bids are due on September 24, 2025, at 2:00 PM, with a public bid opening at that time. Bidders must submit detailed specifications, including outline dimension and nameplate drawings, a Bidder's Proposal and Statement, and a Non-Collusion Affidavit. The City of Colton reserves the right to accept or reject any or all bids, with the final agreement being a City of Colton Purchase Order.

The solicitation does not explicitly mention specific set-aside designations or restrictions on responding organizations. Bidders will be required to provide comprehensive documentation on transformer losses, with a unique penalty calculation for transformers exceeding quoted loss values. The bid package includes a specific formula for assessing no-load and load losses, which will factor into the overall evaluation. While specific budget ranges are not detailed in the provided documentation, the comprehensive transformer specifications suggest a significant procurement investment. The transformers will be delivered to the City of Colton Electric Yard, indicating a localized procurement focused on meeting the electrical infrastructure needs of San Bernardino County. Potential vendors will need to demonstrate technical capabilities in producing transformers that meet precise electrical performance specifications, with particular attention to loss characteristics and voltage configurations. The procurement appears designed to ensure high-quality electrical infrastructure components for the City of Colton's utility operations.
