     trigeneration systems have been used with advantage in the last years in distributed electricity generation systems as a function of a growth of natural gas pipeline network distribution system, tax incentives, and energy regulation policies. typically, a trigeneration system is used to produce electrical power simultaneously with supplying heating and cooling load by recovering the combustion products thermal power content that otherwise would be driven to atmosphere. concerning that, two small scale trigeneration plants have been tested for overall efficiency evaluation and operational comparison. the first system is based on a 30 kw (iso) natural gas powered microturbine, and the second one uses a 26 kw natural gas powered internal combustion engine coupled to an electrical generator as a prime mover. the stack gases from both machines were directed to a 17.6 kw ammonia–water absorption refrigeration chiller for producing chilled water first and next to a water heat recovery boiler in order to produce hot water. experimental results are presented along with relevant system operational parameters for appropriate operation including natural gas consumption, net electrical and thermal power production, i.e., hot and cold water production rates, primary energy saving index, and the energy utilization factor over total and partial electrical load operational conditions.
