Abstract
Conventional power distribution systems have issues such as rising maintenance costs and vulnerability to natural disasters. Inspired by the concept of battery sharing arising globally in the mobility sector, this paper proposes a new system that eliminates distribution lines in areas with low demand density and instead supplies electricity to consumers by battery delivery. The surplus power generated by the output suppression of solar power generation will be charged to the batteries, effectively reducing the cost of charging to zero. The levelized cost of electricity (LCOE) of the battery delivery system is estimated to be 37 JPY/kWh if it is implemented in part of the Kyushu area. It is suggested that, if 2% of the consumers in the area accept removing distribution lines and switching to battery delivery service, the length of distribution lines could be reduced by 11% and the maintenance cost of the distribution sector could be reduced by about 5 billion JPY per year.
