9, 000 Gallons of Turbine Oil

The Bureau of Reclamation is soliciting offers for the procurement of 9,000 gallons of Mobil DTE Heavy-Medium Oil Group I with ISO Grade 68 circulating lubricant for operating turbines at Grand Coulee Dam. This is a brand-name specific procurement driven by technical compatibility requirements, as mixing different oil groups would cause excessive air entrainment and damage critical equipment, and substituting alternative oils would require draining and flushing the entire 120,000-gallon system. The solicitation incorporates detailed ASTM testing specifications covering air release, copper corrosion, density, demulsibility, flash point, foaming characteristics, kinematic viscosity, pour point, rust prevention, oxidation stability, and viscosity index. Award will be made to the lowest-price responsive offer, with evaluation based solely on price. The solicitation number is 140R1726Q0020, issued on April 23, 2026, with offers due by May 13, 2026 at 12:00 PM Mountain Daylight Time; Amendment 0001, issued April 29, 2026, revised specifications and published a brand name determination, and offerors must acknowledge receipt of this amendment.

This solicitation is set aside as a 100 percent Women-Owned Small Business (WOSB) procurement under NAICS code 324191 (Lubricating Oil and Grease Manufacturing) with a small business size standard of 900 employees. The brand name determination document confirms that only Mobil Heavy Medium DTE oil meets the Bureau's requirements, as market research identified that no other manufacturer produces a Group I oil suitable for this application; previous vendor outreach received nine responses, but only two proposed the Mobil product currently in use. Delivery must be completed 30 days after award to Warehouse B Door 6, located at Highway 155, Grand Coulee, Washington 99133, with the contractor responsible for filling the Bureau's storage tanks equipped with 3-inch cam lock connections. The contract will be awarded as a firm fixed-price purchase order based on the quoters' price per gallon applied to the 9,000-gallon requirement. No specific budget range is published, but pricing will be evaluated as a lowest-price selection among responsive quoters meeting the specified product and delivery requirements.
