JERA, its wholly-owned subsidiary JERA Cross, and Ryohin Keikaku, which runs the Muji retail chain, signed an agreement about collaboration related to CO2 emission reduction through, among other things, joint development of solar power plants.

According to Ryohin Keikaku’s statement issued on January 10, 2025, the companies are discussing the establishment of a joint venture that would develop renewable power plants from which environmental value would be supplied to Ryohin Keikaku. “We calculated that if we were to cover Ryohin Keikaku’s entire 40,000t-CO2 emission reduction target through solar generation, we would need to develop approximately 60MW by 2030,” said the statement.

For the first phase of their collaboration, JERA and Ryohin Keikaku are eyeing the development of approximately 12MW within one year of launching the joint business. Currently, a virtual PPA through which the joint venture would sell generated non-fossil certificates to Ryohin Keikaku and power into the wholesale market is being considered. Ryohin Keikaku estimates the development costs for the portfolio to reach approximately 3.6 billion yen.

According to the statement, Ryohin Keikaku currently has rooftop solar power plants at 25 of its standalone stores.

The partnership between JERA Cross and Ryohin Keikaku comes just days after the former announced it would be helping the logistics giant Yamato Holdings with decarbonization.
