The ground-breaking ceremony for a 102.3MW solar power plant took place in Yakumo-cho (town), Futami-gun, Hokkaido, Japan, May 17, 2018.

The ceremony was attended by about 100 people related to the region including those related to the power producer and construction companies and Yakumo-cho Mayor Katsunori Iwamura. It will be one of Japan's largest-scale solar power plants equipped with a storage battery.

The power producer of the mega (large-scale) solar power plant, "Softbank Yakumo Solar Park," is Hokkaido Yakumo Solar Park LLC (SPC: special purpose company), a fifty-fifty joint venture between SB Energy Corp (Minato-ku, Tokyo) and Mitsubishi UFJ Lease & Finance Co Ltd (Chiyoda-ku, Tokyo).

The construction started in April 2018, and the SPC aims to start operation of the plant within fiscal 2020. The plant will be built on flat land that is adjacent to a Pacific coast and long in the north-south direction.

It is a former pasture land (area: about 132ha) formerly owned and managed by Taiheiyo Kisen Kaisha Ltd (Chiyoda-ku, Tokyo) and Taiheiyo Nojo Co Inc (Futami-gun, Hokkaido). At this point, the land is owned by Yakumo Real Estate Service. The SPC rents the land for the power generation project.

The total solar panel capacity of the plant will be about 102.3MW, and the plant will transmit 75MW of electricity to a power grid. It is expected to generate about 100,682,000kWh of electricity, which is equivalent to the amount consumed by 27,967 households, per year. Also, the amount is about 230% larger than the total power demand in Yakumo-cho. The FIT tariff set for the plant is ¥36/kWh.
