Expanding Beyond Electric Vehicles

This agreement represents an expansion into stationary storage battery management. The move broadens Nuvve’s energy management capabilities beyond its core V2G business.
The technology integrates distributed storage assets to improve power system efficiency. It also enhances reliability across the grid.
Poilasne called the contract a first step. He said it demonstrates new possibilities for utilizing storage resources in Japan.
Plans for Future Growth
NUVVE Japan plans to expand this distributed operation model to other regions. The company will leverage existing storage assets across Japan.
The expansion supports stable power delivery infrastructure. It also aligns with grid modernization efforts in the country.
The aggregation model allows NUVVE Japan to participate in multiple market mechanisms. These include both supply-demand adjustment and wholesale electricity trading.
The high-voltage storage battery in Tainai City serves as the initial proof of concept. NUVVE Japan will use this project to demonstrate the viability of its approach.
The company expects to replicate this model with other storage assets. Future agreements will target various regions throughout Japan.
The operation commences in the first half of 2026 with the Tainai City installation.
