The objective of this paper is to assess consumer acceptance of Home Energy Management Systems (HEMS), which are expected to play an important role in constructing new smart grid systems. In order to do that, we carried out a questionnaire survey to determine what personal characteristics are shared by consumers who are more interested in HEMS. We conducted probit analysis on the survey responses. The results showed that environmental consumers are more interested in HEMS. There are three types of environmental consumers: consumers who scrupulously try to reduce electricity use, those who are more interested in energy-saving air conditioners or refrigerators, and those who are more interested in advanced energy saving items such as photovoltaic units and heat pumps. The results also showed that each group of consumers can be characterized differently. Consumers who are more interested in advanced energy saving items tend to be younger, have small children, and spend more time at home. Consumers who are positive about the introduction of HEMS include those who hope to have home renovations done, and those who are favorably-disposed toward HEMS automatic control.
