Abstract

To realize a decarbonized community, it is increasingly important for local governments and various other regional entities to introduce and expand local production of local consumption-type energy systems. We conducted a case study on the regional energy supply using a local energy planning and evaluation system we are developing to promote such localized consumption of energy. Specifically, using actual supply data from local power companies in Nose Town and Toyono Town, reductions in primary energy consumption were calculated by assuming scenarios in which renewable energy and energy management technologies were introduced. The evaluated scenarios included the use of conventional equipment, distributed regional energy supply, the adoption of renewable energy and local power producers and suppliers (PPS), the use of mobility devices such as EVs for energy storage, and optimal control of storage batteries. The results indicate that the introduction of renewable energy can significantly reduce the electricity supplied from grid power outside the area. However, since the actual reduction effects naturally depend on the assumed scale of implementation, evaluation cases based on various scenarios should be accumulated and knowledge should be standardized in the future.
