Recent Japanese industries have been drastically changing the industrial structure due to the deregulation of the Electric Utility Law. The first phase has been deregulated in 1995 for wholesale power business, the second phase in 2000 and third phase is on 2004 and 2005 respectively for partial liberalization in retail power markets. And Independent Power Produces (IPP) or Power Producer Suppliers (PPS) have been emerging in the Japanese power industries. In such circumstances, distributed resources (DR) systems such as micro-gas turbine wind-mill and etc, have been discussing to spread then to the customers. Especially combined heat and power (CHP) system are of high interested items for higher efficiency than conventional power units. Further combined heat, information and power system (CHIPS) is highest concern to spread the DR system as represented to the demonstration project in Hachinohe city.
