YAMAKURA DAM: 13,744 kWp

Located in the prefecture of Chiba, Japan, this 13,744 kWp floating solar plant is installed on a water retention dam, Yamakura dam, with an area of 430,000 m² (43 ha).

The platform is equipped with Classic version of Hydrelio® technology and supports 50,904 floating solar panels of 60 cells (270W KYOCERA standard modules). The total structure covers 32% of the water surface.

For this project, Ciel & Terre supervised the engineering of the floating PV system. Our scope included the supply of our Hydrelio® (manufactured in Japan) and the design of the floating platform.

Anchored at the bottom of the pond, the anchoring solution has been designed to meet a maximum 15.3 m depth and a same water level variation (15.3 m, as the pond can be affected by drought).

Yamakura’s floating solar plant has been operational since March 2018 and generates green electricity to the local grid.
