Nuvve Japan to Launch Major Grid-Scale Battery Storage Project

The new battery storage project will feature a robust rated output of 2MW and a substantial storage capacity of 8MWh, designed to provide 4 hours of continuous discharge. Operations are set to commence in November 2026, contributing to Nuvve Japan’s growing contract capacity, which now totals 6MW across its projects in the region.

The battery system will incorporate cutting-edge technology from Sungrow, a recognized leader in battery solutions. This partnership ensures a high level of performance, safety, and reliability, critical for meeting the demands during peak evening hours.

Masa Higashida, CEO of Nuvve Japan, expressed enthusiasm about the project, stating, “This project represents another important step forward for Nuvve Japan as we continue to work closely with our partners to deploy high-value energy storage assets across the country.” He emphasized the company’s commitment to building a scalable portfolio that balances grid resilience with long-term commercial viability.

Gregory Poilasne, CEO of Nuvve, also highlighted the broader implications of this project, noting that it adds another revenue stream for the company, which will start generating income in late 2026. He remarked, “Together with our European battery projects, it creates a strong and growing revenue stream into late 2026 and early 2027.”

This new grid-scale battery storage project in Mino City represents a significant milestone for Nuvve Japan as it continues to strengthen its position in the energy market. By utilizing advanced technology and strategic market operations, Nuvve Japan is poised to contribute to the transition towards cleaner energy solutions and enhance the resilience of the electrical grid in Japan.

As Nuvve Japan prepares to launch operations, the company remains focused on creating sustainable energy solutions that align with global efforts to achieve a cleaner and more efficient energy landscape.
