We sell the Smart Star series of next-generation energy storage systems for home use in Japan. The series comes equipped with the AI software GridShare that optimizes storage battery operation for home use.
GridShare predicts the power output of solar generation facilities while analyzing and learning household power consumption patterns. It optimally controls the charging and discharging of each battery unit, enabling the efficient operation of both photovoltaic power generation systems and energy storage devices. Using GridShare¡¯s function of remotely controlling the charging and discharging energy storage devices, we seek to commercialize GridShare by working with electricity companies and others to verify demand responses using household energy storage devices, which is drawing attention as a solution to today¡¯s electricity shortages.

With Ïã½¶ÊÓÆµ exclusively selling the Smart Star series of products, an approximate total of 60,000 units (equivalent to 700 MWh/180 MW) have been sold as of the end of January 2025.

Furthermore, we have established IBeeT Corporation, a joint venture with Tokyo Century Corporation, to provide Smart Star systems and other distributed power sources and related equipment through a subscription service with no upfront costs. We are also collaborating with TRENDE Inc. to further promote peer-to-peer (P2P) electricity trading.*1

As a new initiative, we are working on the energy storage plant business¡ªwhich is gaining increasing popularity in Japan¡ªand are advancing the construction of specific energy storage plants, including a project in Toyooka, Hyogo Prefecture, with the Kaneka Group; a project in Suita, Osaka Prefecture, with Osaka Gas and Tokyo Century Corporation; and a project in Fukuoka Prefecture, with the Tokyu Land Corporation Group. Ïã½¶ÊÓÆµ, in partnership with Gore Street Capital Limited, has been selected as a joint operator of a fund established by the Tokyo Metropolitan Government to promote energy generation and storage. The fund has secured over eight billion yen from both public and private sources and has officially commenced operations, focusing primarily on investments in grid energy storage facilities.

In addition to the accumulation of these kinds of energy storage assets, we have also concluded a strategic capital and business alliance with UON Pty Ltd., an Australian off-grid decarbonized energy solutions provider, and are expanding our distributed power supply business operations in Japan to overseas markets. Going forward, we will continue working to create further synergies within the existing investment value chain, through a wide range of initiatives ranging from residential storage batteries to large-scale power plants, and both on-grid and off-grid solutions.
Ïã½¶ÊÓÆµ will continue to work with excellent partners in the evolution of its energy storage device business as we contribute to the realization of the efficient use of renewable energy, the stabilization of the power supply and the creation of a decarbonized society utilizing distributed energy.
