Asahi Corporation (Hamamatsu City, Shizuoka Prefecture) built a mega (large-scale) solar power plant in a coastal area of Obuchi/Okinosu, Kakegawa City, Shizuoka Prefecture, Japan, and had a ceremony to celebrate the electric conduction of the plant Nov 22, 2017.

The plant, "Kakegawa Obuchi/Okinosu Extra-high Voltage Solar Power Plant," was built in two areas between which there is Higashi-oya River. The right and left areas measure about 13ha and 4ha, respectively.

In the past, the areas were designated as an "agricultural/industrial complex," and it was not possible to build solar power generation facilities. In December 2013, Kakegawa City, Shizuoka Prefecture and Asahi Corporation concluded an agreement. The city helped lift the designation and negotiate with local communities while the prefecture helped land reclamation and so forth..

On the right and left banks, 51,375 and 16,380 solar panels were respectively installed. The total capacity of the solar panels is 17.95MW. The plant is expected to generate about 19,750,000kWh of electricity, which is equivalent to the amount consumed by 5,400 households, per year and eliminate 9,500t of CO2 per year.

The solar panel is a polycrystalline silicon type manufactured by Canadian Solar Inc (265W), and the PV inverter is a product of Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC) (500W x 30).

Asahi Corporation has already built 25 solar power plants in the western part of the prefecture, and the latest plant has the largest scale. Also, with the operation of the new pant, the ratio of renewable energy in the power consumption in Kakegawa City increases from 7.4% to 8.8%. The city has a goal of increasing the ratio to 11% by fiscal 2025 but now expects to achieve the goal in fiscal 2018.
