This document outlines a federal contract solicitation for turbine and generator rehabilitation work. The U.S. Army Corps of Engineers Engineering District Tulsa is seeking to refurbish the turbine generating units 1 through 4 at the R.S. Kerr Power Plant in Keota, Oklahoma. Work will include replacing the existing Kaplan turbine runners with new ones rated at 49,300 hp to accommodate rewound generators. Turbine work will focus on head covers, wicket gates, turbine shaft, runner, bearings, operating ring, servomotors, and facing plates. The generators' stator windings will be replaced and rated no less than 37,895 KVA at 0.95 power factor with a temperature rise of no more than 75 degrees C above 40 degrees C when operated at rated load. Generator stator core replacements and field winding refurbishment are optional. Upper and lower bearing pads, thrust bearing shoes, and runners will be refurbished. One new set of thrust bearing shoes will be fabricated as spares.
