Abstract—Energy management systems (EMSs) for electricity consumers which manage energy consumption and control some energy consuming equipment in consumer side are expected to be one of effective measures for optimized energy supply and utilization. On the other hand, it is difficult to clarify the benefit of EMS installation, because EMS does not reduce energy consumption only with its installation but improvement or optimization of energy usage in consumer side should be necessary. In addition, whereas advantages of EMS installation such as energy cost and CO2 emission reduction have been considered, negative (trade-off) factors of energy saving have not been discussed enough. This paper proposes a benefit evaluation approach of EMS and the EMS installation impact on enterprise productivity is considered. Also, simulations using Monte Carlo method are conducted and their results are discussed and evaluated.
