JinkoSolar Holding Co Ltd announced Jan 7, 2019, that it will provide high-efficiency solar panels to a storage battery-equipped mega (large-scale) solar power plant being developed by Tokyu Land Corp, etc in Kushiro-cho, Hokkaido, Japan.

The plant, "Suzuran Kushiro-cho Solar Power Plant (tentative name)," is scheduled to start operation within fiscal 2019.

For the plant, about 92MW of solar panels and a lithium-ion (Li-ion) battery with a capacity of about 25MWh will be installed on about 163ha of idled land. It will be one of the highest-output battery-equipped solar power plants in Japan. The plant is expected to generate about 105,000,000kWh of electricity, which is equivalent to the amount consumed by 21,300 households, in the first year.

The power producer of the plant is an SPC (special purpose company) invested in by Tokyu Land, Mitsubishi UFJ Lease & Finance Co Ltd (Chiyoda-ku, Tokyo) and Green Power Development Corporation of Japan (GPD, Chiyoda-ku, Tokyo). Fuji Electric Co Ltd provided EPC (engineering, procurement and construction) services for the plant.

JinkoSolar's "Cheetah" high-efficiency solar panel using half-cut cells realizes a stable performance and stable output within the temperature range of -40 to +85°C as well as an excellent load bearing performance. So, it can keep a stable, high output in Hokkaido, where temperature is low and snowstorms are common. Thus far, the company has shipped more than 10GW of the solar panel in 18 months.

Tokyu Land started operation of "Riene Matsumae Wind Power Plant," a wind power generation system equipped with a storage battery system in Matsumae-cho, Hokkaido, in April 2019. The total rated output of its wind turbines is 40.8MW. The output of the storage battery system set up near the plant is 18MW.

The storage battery is a sodium-sulfer (NAS) battery of NGK Insulators Ltd, and the inverter for the battery is a product of Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC).
