The Department of the Interior, Bureau of Reclamation, is soliciting proposals for the upgrade of excitation systems at the Canyon Ferry and Yellowtail Powerplants in Fort Smith and Helena, Montana, under solicitation number 140R6026Q0007. The project involves retrofitting existing Eaton/Cutler Hammer ECS-2100 voltage regulators to Basler Electric DECS-2100 models, which includes the installation of new control boards and human-machine interfaces, as well as the removal of outdated hardware. This upgrade is critical for maintaining operational efficiency and safety, as the current systems are beyond their serviceable life, and the estimated cost for a full system replacement is significantly higher than the proposed upgrade. Quotes are due by February 16, 2026, at 1500 MST, and must be submitted via email to the designated contacts. The contract period is set from February 16, 2026, to May 17, 2027, and this opportunity is a Total Small Business Set-Aside under NAICS code 335311.
