Following Paris agreement, the Japanese government has asked local municipalities to formulate a ‘Decarbonization plan’. In order to build up an effective action plan, it is necessary to clarify energy supply and demand structure in a regional scale. However, the official statistics of energy data which is the basis of understanding the regional energy structure is not sufficiently organized at the municipal scale in Japan. Therefore, in this research, we aim to suggest the way to clarify regional energy supply and demand structure through drawing energy flow charts.
Moreover, we also analyze changes in regional energy system introducing renewable energy resources and evaluate their impacts on carbon emissions reduction and improvement of energy system efficiency on data analysis. These data set has been collected from the operational characteristics of smart community projects underway in Miyako city, Iwate prefecture. A smart community aims an innovative energy system introducing ICTs to improve efficiencies as well as QOL. In the project, electricity generated from 4 MW PV plants is supplied to the customer facilities through the integration by CEMS （Community Energy Management System）. The accumulated data from smart meters and the EMS （Energy Management System） is also used in the analysis.
