SAN DIEGO & TOKYO--(BUSINESS WIRE)-- Nuvve Holding Corp.

Its technology is recognized as a mechanism for integrating distributed storage assets to improve the efficiency and reliability of the entire power system.

NUVVE Japan is committed to supporting the social infrastructure for stable power delivery and is implementing the evolution of the power network through the effective utilization of existing facilities and adaptation to new market designs.

“This contract is the first step, demonstrating new possibilities for utilizing storage resources in Japan,” added Poilasne.
