The City of Pasadena Water and Power Department seeks qualified firms to provide ongoing maintenance services for inlet air chillers serving gas turbines at the Glenarm Power Plant in Pasadena, California. The scope of work includes preventative maintenance, inspection, repair, and emergency services for three gas turbine units: GT-3 and GT-4 (GE LM6000 simple cycle, 47 MW each with McQuay WDC 126 chillers at 2,200 tons each, commissioned October 2003) and GT-5 (combined cycle with GE LM6000 turbine and Shin Nippon steam turbine, 67 MW total capacity with two Trane CVHF0870 centrifugal water chillers commissioned December 2016). The chillers utilize closed-loop chilled water systems to maximize gas turbine power output under certain operating conditions.
