IBIDEN Engineering Co., Ltd. Starts

Japan’s Largest Water Floating Solar Power Generation

at the Closed Lumberyard Parking Site of IBIDEN’s Kinuura Plant

IBIDEN Engineering Co., Ltd. (Head Office: Ogaki City, Gifu Prefecture; President and

Representative Director: Hidetoshi Yamauchi) started operation of the Japan’s largest water

floating solar power generation plant, which employs in-house developed floats, at the closed

lumberyard parking site of IBIDEN’s Kinuura Plant. The new plant started power generation on

February 15, 2016, and celebrated its successful opening ceremony on March 14, 2016.

The water floating solar power generation system has 7,680 solar panels and is expected to

have a certificated output of 1.99 MW and an annual output of approximately 2,400 MWh. This is

almost equivalent to annual energy consumption of 660 households and offsets an annual

reduction of approximately 1,120 tons of CO2. All electricity generated is sold to the power

company.

To install the water floats, the Company developed a lightweight, corrosion-resistant and

high-density polyethylene that is patent-pending. Solar power generation output usually drops in

the summer due to the rise in outside air temperature, however , the water floating system,

possibly reflecting a cooling effect, is expected to boost power generation 5% compared to the

land-based system.

In these operations, the IBIDEN Group continues to respect people and the global

environment.
