The BonEffice system combines a performance and decisions-support software with engineering and economic analyses. This is provided as a continuous efficiency improvement plan as well as by permanent help desk support. Unlike existing market systems, typically advertised as advisory systems, BonEffice provides real time data on how much fuel can be saved by measuring how close the process parameters are to optimal in a given power plan unit. BonEffice model works even if the data is incomplete and relatively low quality.
