Merchant Bankers (MBK) formed a capital and business alliance with and took a 20% stake in the start-up licensed aggregator Energy Point for 3 million yen amid its efforts to diversify from real estate into renewable energy, the TSE Standard-listed investment company announced on October 6, 2025.
According to the statement, the partnership will allow MBK to access the license and know-how necessary to operate grid-scale battery storage projects. Energy Point expects the tie-up to provide it with the financial and operational backing, as well as the credibility of a publicly traded company, required to build an aggregation business.
MBK said the two companies will jointly develop grid-scale BESS projects, with Energy Point aggregating the assets once operational. The company aims to build three 2MW/8MWh projects by the end of 2026. It plans to select sites across multiple TSO areas from Hokkaido to Kyushu to diversify risk.
Energy Point was founded in July 2023. Prior to MBK’s investment, the company’s founder and CEO Hikaru Nemoto owned 50%, with two other individuals holding 45% and 5%, respectively.
MBK expanded its investment focus to include renewable energy in May 2025. Since then, it partnered with REIT Co. and Taiwan-based EUKA Power to develop grid-scale battery storage projects. It has also been developing solar power plants for HT Solar jointly with the former.
