Nuvve and Volt Establish “NuvveVolt” to Enter Korea’s National-Scale ESS Market

NuvveVolt will participate in the 2025 KPX Energy Storage Systems Central Auction

SAN DIEGO & SEOUL, South Korea--(BUSINESS WIRE)--Nuvve Holding Corp. (“Nuvve”) (Nasdaq: NVVE), a global leader in grid modernization, energy storage and vehicle-to-grid (V2G) technology, today announced its registration with South Korea–based Volt to participate in the 2025 Second-Round ESS Central Auction with the Korea Power Exchange (KPX), marking Nuvve’s first formal entry into the rapidly expanding Korean energy-storage market.

“The creation of NuvveVolt represents a major milestone in Nuvve’s Asia-Pacific expansion strategy,” said Masa Higashida, CEO of Nuvve Japan. “Korea is one of the world’s fast moving energy storage systems markets, and our collaboration with Volt positions us to deploy our intelligent energy-management platform at national scale.”

Registration was completed on December 4, enabling the consortium, led by Nuvve Japan and Volt, to move forward on a national-scale battery-energy-storage (BESS) project totaling 95 MW / 570 MWh. Bid submission for the auction is scheduled for January 12, 2026 and award announcements expected in mid-February.

“Nuvve’s technology foundation was originally built to deliver advanced grid services by aggregating highly distributed and unpredictable electric vehicle batteries,” said Gregory Poilasne, CEO of Nuvve. “We have created sophisticated tools for managing these dynamic assets and are now applying this expertise more broadly for any type of storage across various geographic regions, including Asia, to stationary storage and microgrid solutions.”
