Toshiba’s semiconductor facilities adopt off-site PPA model for renewable energy procurement

Toshiba Electronic Devices & Storage Corporation has implemented off-site power purchase agreements (PPAs) to secure renewable energy for its two semiconductor manufacturing facilities: Kaga Toshiba Electronics Corporation in Ishikawa Prefecture and Himeji Operations – Semiconductor in Hyogo Prefecture. Both facilities will receive renewable energy with additionality from newly built solar power plants.
Under Toshiba Group’s "Environmental Future Vision 2050," the company aims to counter climate change and achieve net-zero greenhouse gas emissions across its manufacturing sites by fiscal year 2030. The adoption of off-site PPAs complements existing on-site PPA models and other renewable energy initiatives.
Kaga Toshiba has partnered with Hokuriku Electric Power Company for its off-site PPA, starting renewable energy use in June 2025. The facility expects to procure approximately 27 GWh annually by fiscal year 2027, reducing greenhouse gas emissions by about 13,000 tons per year, equivalent to the emissions of roughly 5,000 households.
Himeji Semiconductor, under an agreement with Kansai Electric Power Company, began using renewable energy in April 2025. It procures approximately 6.2 GWh annually, resulting in an emissions reduction of about 2,500 tons per year, equivalent to around 1,500 households. Since April 2022, Himeji Semiconductor has achieved 100% renewable energy consumption. Kaga Toshiba’s new 300-millimeter wafer fabrication facility, operational since February 2025, also operates on 100% renewable energy.
Both facilities will continue to optimize their renewable energy mix through off-site PPAs. Power semiconductors produced at these sites support electricity supply and control, contributing to reduced power consumption. Toshiba Devices & Storage Group aims to further environmental conservation and sustainability through its manufacturing practices.
