NUVVE Japan Pioneers Grid Innovation with First Aggregation Agreement for Stationary Storage Batteries
Nuvve Holding Corp. (Nasdaq: NVVE), a global leader in grid modernization and vehicle-to-grid (V2G) technology, has announced a groundbreaking achievement through its subsidiary, NUVVE Japan Corporation. The company has successfully secured Japan’s first aggregation agreement targeting existing stationary storage batteries. This milestone marks a significant step forward in the country’s efforts to enhance grid stability and optimize energy resources.
The agreement involves a high-voltage storage battery located in Tainai City, Niigata Prefecture. With an impressive output of 1,999 kW and a capacity of 8,170 MWh, this grid-scale storage system is designed to absorb the peak power consumption of hundreds of households throughout the year. Operations are slated to commence in the first half of 2026, positioning this project as a cornerstone for future energy innovations in Japan.
“This scale is standard for grid-scale storage batteries in Japan and is capable of absorbing the peak power consumption of hundreds of households throughout the year,” said Gregory Poilasne, CEO and Founder of Nuvve. “It represents a critical advancement in leveraging energy storage to stabilize the grid while supporting renewable energy integration.”
NUVVE Japan’s Role as Aggregator
Under the terms of the agreement, NUVVE Japan will act as the aggregator, responsible for market operations and control. The company will primarily participate in Japan’s supply-demand adjustment market and the wholesale electricity market. By doing so, NUVVE Japan aims to generate revenue for the client while contributing to regional power stabilization. This dual focus underscores the company’s commitment to balancing economic benefits with societal impact.
As an aggregator, NUVVE Japan will leverage its advanced energy control technologies to optimize the performance of the storage battery. These technologies enable real-time monitoring, predictive analytics, and dynamic adjustments, ensuring that the battery operates efficiently and effectively within the broader energy ecosystem. This capability not only enhances grid reliability but also maximizes the value of existing infrastructure.
A Legacy of Innovation in Energy Management
Based in the United States, Nuvve Corporation has long been recognized as a pioneer in V2G (Vehicle-to-Grid) technology—the first company to commercialize this groundbreaking innovation on a global scale. Over the years, Nuvve has deployed its energy control solutions across multiple countries, demonstrating their ability to enhance grid stability and flexibility. Its technology serves as a mechanism for integrating distributed energy resources, such as stationary storage systems and electric vehicles, into the power network.
This expertise positions Nuvve at the forefront of the energy transition, enabling the efficient utilization of renewable energy sources and reducing reliance on traditional fossil fuels. In Japan, where the push toward decarbonization and energy independence is gaining momentum, Nuvve’s solutions offer a timely and impactful contribution.
Supporting Japan’s Power Infrastructure Evolution
NUVVE Japan is dedicated to advancing the nation’s social infrastructure for stable power delivery. By effectively utilizing existing facilities and adapting to new market designs, the company is helping to evolve Japan’s power network. This approach aligns with the government’s goals of achieving carbon neutrality by 2050 and promoting the widespread adoption of renewable energy.
“This contract is the first step, demonstrating new possibilities for utilizing storage resources in Japan,” added Poilasne. “It highlights how innovative aggregation models can unlock the full potential of distributed energy assets.”
The Tainai City project exemplifies how existing infrastructure can be repurposed to meet modern energy challenges. By aggregating and optimizing stationary storage batteries, NUVVE Japan is creating a blueprint for other regions to follow. This model not only reduces costs associated with building new facilities but also accelerates the deployment of sustainable energy solutions.
Expanding the Distributed Operation Model
Looking ahead, NUVVE Japan plans to expand this distributed operation model to various regions across the country. By leveraging existing storage assets, the company aims to create a decentralized yet interconnected energy ecosystem. This strategy will enhance grid resilience, support renewable energy integration, and provide economic opportunities for stakeholders.
The scalability of Nuvve’s technology ensures that it can be adapted to different contexts and requirements, making it a versatile tool for addressing Japan’s unique energy landscape. Whether in urban centers or rural areas, NUVVE Japan’s solutions are designed to deliver tangible benefits, from improved grid stability to increased energy efficiency.
A Catalyst for Broader Energy Transformation
The successful conclusion of this aggregation agreement underscores NUVVE Japan’s leadership in driving grid modernization. By pioneering the use of stationary storage batteries in this capacity, the company is setting a precedent for others to emulate. This initiative reflects a broader trend toward harnessing distributed energy resources to build smarter, more sustainable power systems.
As Japan continues its journey toward a greener future, collaborations like this one between NUVVE Japan and local partners will play a pivotal role. They demonstrate the importance of innovation, cooperation, and forward-thinking policies in achieving national and global energy goals.
