Cogeneration is defined as the generation of electric power and coincident recovery of useful thermal energy from a single prime mover using a single fuel. The 1 MW gas turbine cogeneration system at Texas Department of Mental Health and Mental Retardation (TDMHMR), Austin, came on line in March, 1992 and is a unique application of federal and state funds. This system has been analyzed for its present performance and loads using hourly measured data. The Energy Systems Laboratory (ESL) at Texas A&M University has been collecting hourly data for natural gas use and the electrical energy produced by the engine since August, 1992. Waste heat recovered by the Waste Heat Recovery Boiler (WHRB) is also monitored. This paper describes the present system, analyzes the system using hourly monitored data, calculates energy and dollar savings, compares the measured results with the estimated savings, and discusses some of the problems encountered during the first year of operation.
