The acceleration of diffusion of the DER (distributed energy resources) is hoped for because of the promotion for highly effective use of energy, especially in the house and commercial section in Japan. From this point of view, it is necessary to focus on the feature of DER such as intermittent renewable resources, low quality and low density. The purpose of our study is to clarify the demand of multi (involved low) quality energy and to solve the problem which is optimization of the energy network supply system whose alternative is DER system and large power grid. For these reasons, in this paper, we drew up and sent out questionnaires and analyzed them by CVM. After we evaluated the potential of the multi-quality energy supplying system, we concluded that low energy quality have enough possibility to supply for some of the home appliance.
