Denison Substation Stage 10, Iowa

The Denison Substation Stage 10 project in Iowa is a federally funded construction solicitation under the U.S. Department of Energy’s Western Area Power Administration, issued as a sealed bid with the solicitation number 89503426BWA000067 and posted on July 7, 2026, with responses due by July 14, 2026. The contract is set aside for small business concerns, with clauses 52.219-6 and 52.219-8 indicating a total small business set-aside and utilization requirements, both containing authorized deviations effective December 2025. The scope centers on constructing critical infrastructure at the substation, including installing a new control building with government-furnished 230-kV panels, relays, and a station battery system; constructing cable trenches connecting to 69-kV, 161-kV, and 230-kV yards; replacing two existing cable trench crossings; removing and reinstalling fiber optic cable between key station points; and providing station service equipment, grounding systems, conduits, and associated electrical components. The work must adhere to WAPA’s Construction Standards, Standard Drawings, and Electrical Equipment Standards, with the Project Specifications taking precedence in case of conflict. All work must be completed within 600 days after the notice to proceed at the designated delivery location in Huron, South Dakota. The contract is awarded on a lowest-price, technically acceptable basis, with a strict all-or-none pricing requirement: failure to price every line item renders a bid nonresponsive, and evaluation includes scrutiny of unbalanced bids related to mobilization under WES-M-2002. The project incorporates key Federal Acquisition Regulation clauses including termination for convenience, default for fixed-price construction, value engineering for construction, and incorporation by reference of other clauses through 52.252-2 and 52.252-6, with deviations properly noted. Bid submission requires sealed original and one copy via FedConnect only, signed SF 1442, Section B pricing, and complete System for Award Management (SAM) representation with active UEI and CAGE codes maintained throughout the contract life. Contract administration is handled by Western Area Power in Billings, Montana, with primary points of contact including Contracting Officer Jonathan Dittmer and Contract Specialist Curtis Richter. All correspondence must go through Procore to the Contracting Officer
