Mitsubishi Chemical installs 1,982.4 kW floating PV at Hiroshima plant
- Installation capacity 1,982.4 kW of floating photovoltaic panels on the plant's regulating reservoir.
- Estimated annual reduction of 1,000 t‑CO2/year, equivalent to 2.2 GWh/year.
- Operations started August 1, 2026 at the Hiroshima Plant's flood control basin.
- KYORAKU CO., LTD. installed, owns and operates the system under an on-site PPA while the plant purchases the generated electricity.
Project overview
Mitsubishi Chemical installed a floating photovoltaic power generation system on the regulating reservoir at its Hiroshima Plant, and the system began supplying electricity on August 1, 2026.
Technical details
The installation capacity is 1,982.4 kW. The company estimates annual CO2 emissions will be reduced by 1,000 t‑CO2/year, equivalent to approximately 2.2 GWh/year.
Operational model
The project is organised as an on-site Power Purchase Agreement (PPA). KYORAKU CO., LTD. is responsible for installing, owning and operating the generation system on site, while the Hiroshima Plant purchases and consumes the electricity generated.
Expected benefits
Floating deployment allows use of renewable energy without new land development and enables direct on-site consumption, which reduces transmission losses and grid fees and improves power-use efficiency. The company intends to switch part of the plant's power to the generated renewable electricity to help reduce CO2 emissions.
