■ The Challenges We Face
Soaring electricity prices have become a serious issue for both households and businesses. Behind this is Japan's inherent vulnerability of relying on imported fuels. In Japan, where the energy self-sufficiency rate remains at around 13% (FY2022, Agency for Natural Resources and Energy), geopolitical risks such as the situation in the Middle East directly affect electricity bills. Expanding renewable energy is the most important task to change this structure.
On the other hand, with the rapid spread of solar power generation, a new problem of "not being able to fully use the generated electricity" has emerged. During times of low demand, such as daytime on sunny days, power generation exceeds demand, and the practice of unavoidably stopping solar and wind power generation, known as output curtailment, is becoming a norm nationwide. On March 1, 2026, output curtailment was implemented for the first time in the Tokyo area, which had previously been unaffected, marking the beginning of an era where curtailment is implemented in all 10 areas nationwide. The volume of output curtailment continues to trend upward (Agency for Natural Resources and Energy, "Long-term Outlook for Renewable Energy Output Curtailment, etc.", March 16, 2026). Discarding electricity generated domestically without using fossil fuels is an unacceptable loss from the perspectives of both energy security and economic rationality.
The core of the solution lies in storage batteries. By storing surplus electricity and releasing it when needed, renewable energy can be utilized without waste. Furthermore, from April 2026, institutional reforms will be implemented that allow small-scale storage batteries and power plants to participate in the electricity supply-demand adjustment market. In March of the same year, a "Bill Partially Amending the Electricity Business Act" was also approved by the Cabinet, establishing the legal foundation for the market. Just as the financial "Big Bang" once opened up securities trading to the public and trading volume surged, Japan's electricity market is now at a historic turning point where all players, from power companies to general enterprises, small and medium-sized businesses, and individuals, can participate, and trading volume will expand explosively.
To reap the benefits of this transformation, an advanced platform is indispensable to centrally manage power plants and storage batteries dispersed nationwide in real-time and respond quickly to increasingly complex market rules. "Tensor Cloud," developed by Tensor Energy, solves this problem utilizing AI. From predicting power generation to revenue management, optimal operation of storage batteries, and responding to market transactions, it provides the functions necessary for power generators.
