Chugin Energy partnered with Clean Energy Connect to offer off-site PPAs starting with a 2MW deal to supply its group company Chugoku Bank, the companies announced on August 7, 2025. On the same day, the scheme partly started operations.
According to the statement, Chugin Energy will build 20 to 21 small-scale solar power plants in Okayama and Hiroshima prefectures and supply their output to nine of the bank’s facilities including its main branch in Okayama City. Once fully operational, the projects’ annual output is expected to reach about 2.1GWh.
Clean Energy Connect will support development and operations. It is unclear whether the company, which is a licensed power retailer, will also sleeve the PPA. Chugin Energy does not have the necessary license.
The companies said they plan to use the intra-group PPA as a case study for offering similar schemes to other companies.
Chugin Energy, established in 2023, has been focusing on installing rooftop systems at Chugoku area businesses under on-site PPAs. As of the end of June 2025, it operated 47 solar power plants totaling about 15.5MW. The deal with Chugoku Bank is its first off-site PPA.
Clean Energy Connect specializes in developing distributed low-voltage solar projects for physical and virtual off-site PPAs. The company operated about 2,300 power plants totaling 200MW as of the end of July 2025, up from about 1,500 totaling 130MW in late June 2024. It has signed deals as large as 70MW with companies including Google, Amazon, and NTT Anode Energy.
