Reducing 278 tons of CO2 emissions per year. A floating photovoltaic system on the pond adjacent to the Hirakata Plant in Japan, has entered full-scale operation

KYOCERA Document Solutions Inc. (President: Takashi Nagai) announces that, from January 2026, its Hirakata Plant (Osaka) has begun using power generated by a floating photovoltaic system utilizing the agricultural reservoir “Moya Pond,” which adjoins the plant. The photovoltaic system was installed by Kyocera EPA LLC, and the generated power is supplied to the plant under a PPA (Power Purchase Agreement) model.

The Hirakata Plant had previously introduced renewable energy, with rooftop solar installations, but securing additional installation sites became a challenge as generation capacity expanded. Floating photovoltaic systems make effective use of reservoir surface area and can be installed without the large-scale earthworks or land alterations required for newly created ground-mounted systems, thereby reducing environmental impact.

The new installation is expected to supply approximately 663 MWh of electricity annually, equivalent to about 5.3% of the plant’s annual electricity consumption. Annual CO2 emissions are projected to be reduced by approximately 278 metric tons (equivalent to 19,857 trees*). In addition, by returning fees for use of the reservoir surface to the local community as maintenance and management payments, the project contributes to addressing regional issues.
