Kioxia Installs Solar Power Generation Systems at Kitakami and Yokkaichi Plants in Japan in Major New Sustainability Initiative

Kioxia Group is increasing the usage of renewable energy by installing large-scale solar power generation systems for the first time at its Kitakami Plant and Yokkaichi Plant. Installed on the rooftop of flash memory fabrication facilities, the new solar power systems will be the largest of their kind at any semiconductor plant in Japan.¹ With a total generating capacity of about 7.5 megawatts (MW), the new solar power systems are expected to generate about 7,600 megawatt hours (MWh) of electricity annually for Kioxia and reduce carbon dioxide emissions by about 3,200 tons per year. With the new solar power systems, we will accelerate our efforts to address climate change, one of the key objectives of our management strategy.

The solar power generation system at Fab1 of our Kitakami Plant became operational recently while the system at Fab6 of our Yokkaichi Plant will be operational in June of this year.

Kioxia Group has set the goal of sourcing 100% of its energy from renewable sources by FY2040, including solar power. We will continue to address climate change proactively and aim to develop sustainably for the benefit of society.

Summary of Kioxia Group’s Solar Power Generation System
	Kitakami (Fab1)	Yokkaichi (Fab6)
Power generation capacity	Approx. 3,600 kW	Approx. 3,900 kW
Estimated annual power generation	Approx. 3,500 MWh	Approx. 4,100 MWh
Annual CO₂ reduction	Approx. 1,600 tons	Approx. 1,600 tons
Operation start date	January 20, 2023	Scheduled for June 2023

The systems will be operated and maintained under a Power Purchase Agreement (PPA) model.²

¹ Based on Kioxia research (as of February 1, 2023)
² PPA operators own the solar power generation equipment and are responsible for installation and maintenance of the system; third parties that make the necessary space available (in this case Kioxia) purchase the electricity generated at the sites from the operators.
