West Energy Solution Inc announced that it will build a 2.688MW floating solar power plant on a reservoir in Takamatsu City, Kagawa Prefecture, Japan.

West Energy Solution (Hiroshima City) is a subsidiary of West Holdings Corp. The mega (large-scale) solar power plant will be the largest-scale floating solar power plant in Japan, the company said.

The plant will be installed on the surface of "Shin-ike," a reservoir that the city owns in Kawanaihara, Kagawa-chou, Takamatsu City. West Energy Solution will rent part of its water surface (about 250,000m2) and set up about 10,000 solar panels, aiming to start power generation in July 2016.

West Energy Solution will become the power producer for the plant and provide EPC (engineering, procurement and construction) services. The solar panel and PV inverter employed for the plant are products of West Holdings and Toshiba-Mitsubishi Electric Industrial Systems Corp (TMEIC), respectively. The project cost is expected to be about ¥800 million (approx US$6.49 million).

On the reservoir, three companies including West Energy Solution plan to build mega solar power plants with a total output of 8.1MW.

In May 2015, Kyocera Corp and Century Tokyo Leasing Corp (TC-Lease) started operation of "Hyogo Kasai City Sakasamaike Floating Mega Solar Power Plant" (output: about 2.3MW) on the surface of the "Sakasamaike" reservoir in Kasai City, Hyogo Prefecture (See related article).

The output of the floating solar power plant to be built by West Energy Solution (output: 2.7MW) will exceed the output of Hyogo Kasai City Sakasamaike Floating Mega Solar Power Plant and will be the largest of all the floating solar power plants in Japan.

Also, West Holdings has so far dealt with floating solar power plants in Saitama, Osaka and Saga prefectures (See related article 2).
