In order to realize a carbon-neutral society by 2050, the government is aiming to make variable renewable energy sources such as photovoltaic panel and wind power generation the main source of electricity. To achieve this goal, it will be necessary to increase the electrification ratio on the building side, adjust electricity supply and demand through storage batteries (including EV batteries) and demand response, and utilize hydrogen. In order to study how much of these devices and systems should be installed in a city, it is essential to have an urban energy simulator that can not only calculate the total annual amount, but also analyze energy supply and demand fluctuations by the minute. In this module, we will construct an urban energy supply-demand simulator based on GIS data as a platform that can examine future urban energy systems, and propose what the future urban energy system should be like. The simulator to be developed can evaluate the impact of the introduction of various energy element technologies into a city, and will contribute to the formulation of urban energy policies.
Concept of the research
This research is unique and different from previous studies in that it can analyze the energy demand of individual buildings, areas, and even the city level, including energy peaks, with calculations at five-minute intervals. Another novel aspect is the incorporation of transportation energy into urban energy calculations in anticipation of the future connection of electric vehicles to the grid.

Fukuoka City government has declared that it will reach carbon neutrality by 2040. In our ongoing research, we are performing calculations for Fukuoka City and hope to demonstrate the feasibility of this goal in line with the city’s declaration. If possible, we would like to collaborate with the Fukuoka City government to study the urban energy policy of Fukuoka City as a prototype to demonstrate the usefulness of this simulator, thereby serving as a foothold for the widespread social implementation of the results of this research.
In addition, we are also conducting a study in Oki Island Town, Shimane Prefecture, and can propose how energy systems should be in areas with declining populations. We intend to appeal to the importance of urban energy planning to society by publicizing the study’s results.
