Nuvve Denmark ApS, a subsidiary of Nuvve Holding Corp. (Nasdaq: NVVE), a global leader in distributed grid assets management and vehicle-to-grid (V2G) technology, and E&B Renewables ApS, a Danish developer of renewable energy projects, have entered into a Non-Binding Memorandum of Understanding (MoU) to deploy Battery Energy Storage Systems (BESS) in Europe. This MoU establishes a framework based on the collaboration initiated with the three projects announced by Nuvve in Denmark in November 2025.

Under the agreement, the parties expect to develop a diversified portfolio of stationary batteries that will be managed by Nuvve. The projects are expected to include battery power capacity from 2 MW to 100 MW that will be interconnected to the grid.

E&B Renewables and Nuvve plan first to deploy 3 projects in Denmark, each at 2 MW. In early 2026, the partnership intends to secure an additional 20 to 50 MW of projects throughout the Nordic and Baltic countries. Recent market conditions in these markets allows for potential revenues respectively of approximately 2,000,000 kr/MW-yr ($340,000 MW-yr) and 3,400,000 kr/MW-year ($532,000/MW-yr) depending on the location in Denmark and 480 000€/MW-year ($570,000 /MW-yr) in Estonia. These projects usually have a 15-year life span.

The partners intend to target projects where the revenue risk can be hedged over the course of the batteries’ life, across multiple value streams, beyond arbitrage and grid services, thanks to the Nuvve platform, that unlocks potential behind-the-meter services, energy communities, local flexibilities for network operators and physical flexibility purchase agreements (FPA) with prosumers on or next to BESS sites. The MoU is non-binding but reflects the intent of Nuvve and E&B Renewables to cooperate in good faith towards a partnership to pursue the foregoing projects.

“This agreement is the beginning of the materialization of the previously announced expansion of our focus to stationary storage and microgrids,” said Gregory Poilasne, CEO of Nuvve Holding Corp.

“E&B Renewables is eager to work with Nuvve to identify the best projects that offer high yields, low risk, and short time to market,” said Nicolaj Brask Christiansen, co-CEO of E&B Renewables.

“The value of the projects developed by E&B will be brought to a new level by Nuvve’s grid asset management technology which enables upside and risk mitigation from diversification of revenue streams,” added Matias Bøje, co-CEO of E&B Renewables.
