NUVVE JAPAN Signs 20-Year Merchant Aggregation Agreement for 2MW/8MWh Grid-Scale BESS in Kani City, Gifu

— Strengthening Asset Management Portfolio and Advancing VPP Strategy Through Multi-Market Operation —

NUVVE JAPAN K.K. (Headquarters: Tokyo; hereinafter “NVJ”), a leader in advanced energy aggregation, is pleased to announce the execution of a 20-year Merchant Aggregation Agreement with a Taiwanese corporation operating in Japan . The aggregation agreement is for a 2MW / 8MWh grid-scale Battery Energy Storage System (BESS) currently under development in Kani City, Gifu Prefecture.

The project is scheduled for grid connection in January 2027 . As the designated aggregator, NVJ will provide end-to-end market integration and AI-driven dispatch optimization for the asset. NVJ has already received a subscription fee of $70,000.

Strategic Context: Expanding Asset Management and VPP Roadmap

As Japan’s power grid evolves with the rapid integration of renewable energy, grid-scale BESS has become critical infrastructure for maintaining frequency stability and managing supply-demand imbalances.

This agreement marks another milestone in NVJ ’s expanding portfolio battery by aggregation services under management . By integrating this 8MWh utility-scale asset into its platform, NVJ is demonstrating steady progress toward its comprehensive Virtual Power Plant (VPP) vision , which seeks to orchestrate diverse energy resources—from EV fleets to large-scale stationary batteries—to enhance grid resilience.

By adopting a "Full-Merchant" model , NVJ will leverage its advanced aggregation platform to maximize value across three key Japanese power markets:

1. Japan Electric Power Exchange (JEPX): Arbitrage through energy time-shifting.
2. Ancillary Services Market: Providing frequency regulation and grid stability (delta-kW).
3. Capacity Market: Monetizing the long-term reliability and availability (kW value) of the storage asset.

The combination of these services brings an expected value between $255,000 and $382,000 of margin for the 2MW annually.

Project Overview

• Location: Kani City, Gifu Prefecture
• Rated Power Output: 2 MW
• Storage Capacity: 8 MWh (4-hour duration)
• Commercial Operation: January 2027 (Planned)
• Contract Duration: 20 Years
• Key Roles:
  • Japanese subsidiary of a Taiwanese company: Project development, ownership, and maintenance.
  • NUVVE JAPAN: Asset management, market aggregation, and automated dispatch control.

Future Outlook

The 20-year term of this agreement underscores the long-term confidence in the Japanese storage market and NVJ’s capabilities. NVJ remains committed to scaling its managed asset base and accelerating the realization of a decentralized, carbon-neutral energy society through its sophisticated VPP technology.
