It can procure about 160 MWh of renewable energy annually, diversifying procurement methods alongside existing off‑site PPAs and advancing decarbonization.

The issue involved the storage of molds and other items free of charge in the medical device business, and the company has already completed payment of related costs. They plan to thoroughly implement measures to prevent recurrence and respond accordingly.
HOYA Corporation has concluded an off-site corporate PPA with Marubeni Shin Denryoku for the supply of renewable energy from a solar power plant at the Akishima Factory, aiming to achieve its renewable energy ratio target.
