A webinar hosted online by Japan Branding will explain how utilization rates in the battery storage business affect revenue. It will cover the background, key topics and event details.
Japan Branding Co., Ltd., which plans and operates battery storage systems, announced that it will hold an online webinar in early October 2026 explaining the importance of utilization rates as grid-scale battery storage becomes more widespread. Representative Director Maeda Yuki (前田 雄吉) will serve as the speaker and outline the basic principle that battery storage creates revenue opportunities only when it is operating.
As background, the Central Research Institute of Electric Power Industry states that battery storage is equipment that consumes only the amount lost even when it operates, and that revenue is zero without operation. The Ministry of Economy, Trade and Industry has also provided estimates based on the assumption of 365 days and one cycle per day, while explaining that the current clearing rate in the balancing market is only 60%.
The webinar will cover five main topics: the premise that operation is required, the assumed annual operating schedule, the importance of reliable performance in the capacity market, the realities and challenges of the balancing market, and the trade-off between operation and degradation. The event is scheduled for 19:00-20:00 in early October 2026, will be held online, and is free to attend. Applications can be made through the official website or official LINE account.
