The power producer is Toyama Prefectural Government Enterprise Bureau, and power selling began in March 2016.

The mega-solar plant in Toyama Shinko was developed by utilizing a former waste disposal site undergoing its purification period. It is situated in the Toyama Shinko Coastal Industrial Site (Fig. 2).

In Toyama Prefecture, solar power plants face certain conditions that do not exist in warm regions on the Pacific Ocean side. These conditions necessitate measures against snow cover (Fig. 3).
