Currently decommissioned, Rohr owned and managed the natural gas fired 3.5 MW cogeneration facility which served the Riverside plant with baseload requirements for electricity and steam. Built in 1985 by University Energy of San Diego, the plant consisted of a genset, a bypass stack, an ABCO heat recovery steam generator, and controls. The genset was powered by an Allison 501-KB5 gas turbine equipped with water injection to control NOx emissions. The system ran approximately 6,000 hours a year. It was shut down on weekends by agreement with the City of Riverside municipal utility.

Operating and field service technicians from IPT’s other sites supplemented the staff for shift relief and emergency maintenance help.

IPT provided additional technical, engineering, and management services as requested by Rohr. IPT was responsible for turbine upgrades, emissions retrofit, maintenance and turbine overhaul management.
