Abstract
This paper describes business model of multi-energy system from consumers' points of view to promulgate renewable energy power generation such as photovoltaic power system, wind mill power system and so on. In general speaking, renewable energy system has been introduced with stand-alone unit tied up into large grid system (transmission system). In this case, business model of the system is regarded as supplier side. In contrast, multi-energy network system represented as micro-grid system is regarded as consumer side business model. This consumer side business model has conceivable advantages as comparing to supplier side business model in the field of technical aspect of reliable power supply, economical efficiency and added values in creating community business.
