SIZE & TECHNOLOGY: 4.5 MW Electric, 100,000 lb/hr steam gas turbine / HRSG

IN-SERVICE: Fall 2009

FIRM ROLE: EPC (Engineering, Procure, Construct), Start-up, Commissioning, Close-Out


In an effort to manage production costs in the Northeast, Frito-Lay chose to reduce overall energy costs by installing a combined heat and power plant at their Killingly, CT facility. Waldron was selected as the EPC contractor to install a gas turbine based CHP plant in a stand alone building adjacent to the manufacturing plant. The prime mover selected was the 4.5 MW Centaur 50 gas turbine, manufactured by Solar Turbines. Heat is recovered in a Rentech supplemental fired boiler that produces up to a peak steam output of 60,000 lb/hr. Integral in the boiler is a SCR system to control NOx emissions to 2.5 ppm at the stack.


The plant was named a Pace Setting Plant in the Combined Cycle Journal, second quarter 2009.
