Nuvve Holding Corp. (NASDAQ:NVVE) surged more than 180% in premarket trading Thursday after revealing that its Japanese subsidiary has secured a significant aggregation deal involving stationary storage batteries in Japan.
The agreement covers a large high-voltage storage system located in Tainai City, Niigata Prefecture, featuring 1,999 kW of output and 8,170 MWh of capacity. The company said operations are slated to begin in the first half of 2026.
Under the contract, NUVVE Japan will act as the aggregator, overseeing system control and market participation, particularly in Japan’s supply-demand adjustment market and wholesale power market. The model is designed to deliver revenue for the client while helping stabilize local grid conditions.
“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.
Known for its leadership in vehicle-to-grid technology, Nuvve framed the deal as a strategic step that broadens its energy management activities beyond EV applications. The company’s platform connects and optimizes distributed energy resources to improve grid efficiency and resilience.
“This contract is the first step, demonstrating new possibilities for utilizing storage resources in Japan,” Poilasne added.
NUVVE Japan said it aims to replicate this distributed operating model in additional regions across the country, tapping existing storage infrastructure to support grid stability and emerging modernization efforts.
