Taiyo Holdings Co Ltd announced Nov 21, 2019, that a floating solar power plant with an output of about 1.214MW has started operation on the surface of a pond in Mie Prefecture, Japan.

The plant, "Shijyuku Shin-ike Floating Solar Power Plant," started to sell electricity Oct 31, 2019. It uses a reservoir in Shijyuku-cho, Iga City, Mie Prefecture. It is expected to generate 1,417,000kWh of electricity per year. It sells electricity to Chubu Electric Power Co Inc at a price of ¥18/kWh (excluding tax) based on the feed-in tariff (FIT) scheme.

The power producer of the plant is Taiyo Green Energy Co Ltd (Ranzan-machi, Saitama Prefecture), which is a subsidiary of Taiyo Holdings. The plant became Taiyo Green Energy's 10th solar power plant in operation. All of its solar power plants were installed on water surface.

With the new plant, the total amount of electricity generated by the Taiyo Holdings group's solar power plants increased to about 16.1GWh per year, which is equivalent to 110% of the amount of electricity that the group consumes per year in Japan as of the end of fiscal 2018.

In the past, Taiyo Holdings announced that the amount of electricity generated by its nine floating solar power plants had exceeded its power consumption in Japan as of mid-September 2019, generating enough solar electricity to cover 100% of the power consumption (See related article).

For the Shijyuku Shin-ike Floating Solar Power Plant, Taiyo Green Energy acquired a development plant for which permissions such as facility certification had been obtained, from the original developer, and the company commercialized it.

Taiyo Green Energy entrusted EPC (engineering, procurement and construction) services to Smart Energy Co Ltd (Chuo-ku, Tokyo). Environmental-Resources Development Consultant Co Ltd provided floats for setting up solar panel on the water. The solar panel and PV inverter employed for the plant are products of Hanwha Q Cells Co Ltd and Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC), respectively.
