Tensor Energy Raises ¥950M in Series A Funding

Tensor Energy Inc., a company that provides cloud services automating the operation and financial management of solar power plants and battery storage systems using AI, has completed a Series A funding round, raising a total of 950 million yen from Global Brain, Globis Capital Partners, and Delight Ventures. This is an additional investment from Globis Capital Partners and Delight Ventures, following their investment in the previous round.

The funds raised will be used to enhance the functionality of our flagship product, “Tensor Cloud,” to improve our sales, marketing, and corporate structures, and to increase our workforce, including hiring executives.

Soaring electricity prices are a serious problem for both households and businesses. This stems from Japan’s unique vulnerability: its reliance on imported fuels. In Japan, where energy self-sufficiency remains at only about 13% (FY2022, Agency for Natural Resources and Energy), geopolitical risks such as the situation in the Middle East directly impact electricity prices. Expanding renewable energy is a crucial task for changing this structure.

On the other hand, with the rapid spread of solar power generation, a new problem has emerged: “We cannot use all the electricity we generate.” During periods of low demand, such as sunny afternoons, the amount of electricity generated exceeds the demand, forcing the cessation of solar and wind power generation. This so-called output control is becoming commonplace nationwide. On March 1, 2026, the first output control was implemented in the Tokyo area, which had previously been free from it, ushering in an era where control is implemented in all 10 areas nationwide. The amount of output control continues to increase (Agency for Natural Resources and Energy, “Long-Term Outlook on Renewable Energy Output Control,” March 16, 2026), and the fact that electricity generated domestically without using fossil fuels is being wasted is an unacceptable loss from both an energy security and economic rationality standpoint.

The core of the solution lies in battery storage. By storing surplus electricity and releasing it when needed, renewable energy can be used efficiently without waste. Furthermore, from April 2026, a system reform will be implemented that will allow even small-scale battery storage and power plants to participate in the electricity supply and demand adjustment market. In March of the same year, the “Bill to Amend Part of the Electricity Business Act” was also approved by the Cabinet, establishing the legal foundation for the market. Just as the financial Big Bang opened up securities trading to the public and led to a surge in trading volume, Japan’s electricity market is now at a historical turning point where not only power companies but also general companies, small and medium-sized businesses, and individuals will participate, leading to an explosive expansion of trading volume.

To reap the benefits of this transformation, a sophisticated platform is essential that can centrally manage power plants and battery storage systems distributed across the country in real time and respond immediately to increasingly complex market rules. Tensor Energy‘s “Tensor Cloud” solves this challenge using AI. By integrating all the functions necessary for power generators—from power generation forecasting and revenue/expense management to optimal battery operation and market trading—onto a single cloud, it maximizes the value of renewable energy.
