At Iwamizawa City, Hokkaido, in November 2021, Hitachi, Ltd. and Hitachi Hokkaido University Laboratory, which is a joint research facility with Hokkaido University, established a demonstration facility for a stand-alone nanogrid.
Stand-alone nanogrid is a small-scale power system that realizes the idea of the "local production for local consumption" of energy by providing local regions with their own sources of energy that utilize solar, hot spring gas, and other types of alternative energy.
While promoting smart agriculture for Iwamizawa City, a municipality with a declining farming population, such systems have growing expectations as emergency power sources in times of disaster. This article investigates the details of this initiative.
