Nuvve Denmark ApS, a subsidiary of Nuvve Holding Corp., will develop three battery energy storage system (BESS) projects with a total capacity of 6MW in Eastern Denmark. The installations will be located across Helsingør and Ringsted on the island of Zealand, each offering 2MW of power and two-hour storage duration.
Projects designed for grid services
The new batteries will primarily deliver ancillary grid services and enable energy arbitrage. The company will use its proprietary software platform to manage real-time switching between the most profitable grid services while limiting battery degradation. This approach aims to maximise returns in the Danish electricity market, where the growing share of renewables is creating increasing opportunities for energy storage solutions.
The projects are expected to reach Ready-to-Build status during the first half of 2026, with commissioning anticipated by the end of the same year. Total investment is projected at $10mn, with a potential internal rate of return of 25%, according to the company.
A fast-evolving market
Denmark is pursuing a target of a 100% renewable electricity system by 2030. This shift includes the phase-out of conventional generation, making energy storage critical for grid reliability. In this context, Nuvve aims to expand its footprint with these first commercial stationary battery deployments in the country.
For more than nine years, Nuvve has operated a Virtual Power Plant (VPP) qualified by Danish system operator Energinet for frequency regulation services. The company reports having generated between $400 and $600 per kilowatt-year on smaller-scale projects and expects similar revenue performance from the new assets.
Looking ahead to 2026
These projects represent a strategic milestone in Nuvve’s growth plan in Northern Europe. The company expects to significantly scale up its VPP in the region. Management anticipates accelerating asset deployment starting in 2026, leveraging experience gained in the United States and Japan.
