In September 2019, "Mimayaike Floating Solar Power Plant," a mega- (large-scale) solar power plant with a solar panel capacity of about: 2.8485MW and a grid capacity of 1.99MW, began operation on "Mimayaike," a reservoir in Mimayacho a little way from downtown Takamatsu City, Kagawa Prefecture, Japan (Fig. 1).

Generated power is sold at 21 yen/kWh (hereinafter, excluding tax) based on the feed-in tariff (FIT) scheme to Shikoku Electric Power Co Inc.

A number of reservoirs are scattered around Takamatsu City and other areas in Kagawa Prefecture. There were reportedly more than 20,000 reservoirs at their peak. Even now, Kagawa Prefecture ranks third in the number of reservoirs and top in the ratio of reservoirs to the entire area of a prefecture across Japan.
