Fort Peck Excitation System Upgrade

Summary (Newest Update)

Background The U.S. Army Corps of Engineers (USACE) is seeking information from interested and qualified contractors regarding the potential modernization of excitation systems at Fort Peck Dam, a remote hydroelectric facility located on the Missouri River near Glasgow, Montana. The facility consists of two powerhouses with a total of five generating units. The existing excitation systems present reliability and supportability concerns due to aging equipment, partial legacy upgrades, and obsolescence of key control components. Work Details The work involves modernization efforts for excitation systems at Fort Peck Dam, specifically: - For Powerhouse 1 (Units 1-3): - Existing digital excitation regulator hardware remains serviceable. - Front-end excitation controls, field breakers, and operator interface components are obsolete or experiencing reliability issues. - A targeted modernization approach may include replacing failing or obsolete front-end components while reusing existing regulator hardware and cubicles with necessary modifications. - For Powerhouse 2 (Units 4-5): - Existing excitation systems include legacy components operating beyond their recommended design life. - A full excitation system replacement is being evaluated for these units, which may involve removal of existing equipment and installation of new digital static excitation systems. - The anticipated scope includes modern digital excitation systems, integration with existing generator and plant systems, excitation modeling and validation testing, as well as factory and site acceptance testing. Work will be conducted at a remote location with limited local labor availability and will require coordination across multiple generating units and outage windows. Place of Performance Fort Peck Dam, located on the Missouri River near Glasgow, Montana.
