A 100% CO2-free micro-grid project using cutting-edge technologies in Japan is presented. At first, the overview of new project located in Rokkasho in Japan is introduced. Then the project results are evaluated on self-sufficiency rate in the community using a kind of dispatchable demand response and direct load control, the direct control of heat pump water heaters with a tank. The ratio is also evaluated when battery and control system are demonstrated. The analysis results between the battery capacity and ratio are introduced at last.
