Hokuriku Electric Power Biz Energy Solution is building a 5MWDC ground-mounted solar power plant at Toray’s Ishikawa Factory in Nomi City, Ishikawa Prefecture, the materials manufacturer said on March 4, 2025.
According to the statement, the wholly-owned subsidiary of Hokuriku Electric Power plans to finish construction work this month and start power supply in April 2025. The power plant is expected to generate 6GWh annually, all of which will be used at the 37,000m2, 600-person Ishikawa Factory, which produces polyester and nylon long fibers for the textile industry and carbon fibers for the aviation and sports equipment industries.
The Japan Energy Hub PPA database shows this is Toray’s first publicly disclosed PPA. In March 2022, the company announced that from April of that year 100% of its headquarters’s power consumption would be covered by non-fossil certificates from J-POWER’s wind power plants secured through a scheme organized by the building’s owner Mitsui Fudosan.
Starting from 2022, Hokuriku Electric Power Biz Energy Solution signed numerous PPAs including a 2.46MWDC on-site deal with Fukui Byora and a 6.22MWDC off-site deal with Seven-Eleven Japan.
The contract with Toray is the Hokuriku EPCO group company’s largest on-site PPA. It follows a similar ground-mounted on-site deal between SMFL Mirai Partners and YKK AP and Chubu Electric Power’s off-site PPAs with projects built on offtaker-owned land, showing a broader trend of developers trying to secure projects with large industrial companies that own unused land amid a decreasing number of other sites suitable for larger solar projects.
