Tri-City IPS Expansion â? ? Transformer

Clackamas County Procurement Division, specifically for Water Environment Services (WES), is issuing an Invitation to Bid (ITB #2025-55) for pre-purchasing two identical pad-mounted, three-phase distribution transformers for the Tri-City Influent Pump Station Expansion Project. The procurement aims to increase the pump station's firm capacity from 47.6 million gallons per day (MGD) to 72.4 MGD by replacing existing electrical systems. The transformers are specified as 2,500 kVA units with 12.47kV delta primary and 480/277V wye secondary connections, featuring a dead-front, radial-feed design and liquid-immersed, self-cooled construction. Manufacturers must comply with current Department of Energy efficiency requirements and provide less-flammable, biodegradable dielectric fluid. The bid was issued on June 10, 2025, with bids due on July 15, 2025, at 2:00 PM PST, and delivery of the transformers is required 18 months from the signed purchase order. Bidders must submit detailed documentation including product data and certifications, adhering to specific technical requirements with a focus on equipment performance, safety, and environmental considerations.

The procurement allows for potential intergovernmental cooperative purchasing, enabling other public agencies to potentially purchase under the contract's terms. While specific set-aside designations are not explicitly mentioned in the documentation, the bid appears open to qualified manufacturers and suppliers who can meet the technical specifications. The transformers will integrate with existing pump station infrastructure, replacing current electrical systems to support expanded capacity. No incumbent vendors are identified in the provided documentation. The procurement represents a significant infrastructure investment for Water Environment Services, though specific budget ranges or award values are not disclosed in the available materials. Bidders will need to demonstrate technical competence, compliance with efficiency standards, and ability to provide transformers that meet the precise electrical and environmental specifications outlined in the invitation to bid.
