Partnership Opens New Revenue Market

Nuvve Holding Corp. (NASDAQ:NVVE), a global leader in advanced energy storage and grid modernization solutions, today announced it is partnering with OMNIA Global to jointly address a pipeline in excess of 1 GW over the next 24 months with the supporting financing. The first and earliest project is a 50MW/75MWh European CE-approved battery energy storage system (BESS) located in Sweden. This marks a significant expansion of the company's European energy storage footprint.

BESS plays a critical role in modern electricity grids by balancing supply and demand, integrating renewable energy, and enhancing grid stability. BESS technology enables the storage of excess energy generated during periods of low demand and its rapid deployment during peak usage, improving reliability while reducing dependence on fossil fuel-based generation.

Sweden represents one of Europe's most attractive markets for energy storage investment, driven by its ambitious climate goals, high penetration of renewable energy, and well-developed electricity market. The country's growing wind and solar capacity, combined with increasing electrification across transportation and industry, has created strong demand for flexible storage solutions. Supportive regulatory frameworks and market structures further enhance the commercial viability of BESS assets, positioning Sweden as a strategic hub for long-term energy storage development.

The first project is expected to commence operations during the second quarter of 2026. It forms part of Nuvve's broader European development pipeline, which includes battery storage sites in several of the continent's best-performing energy markets.

Recent market conditions in these regions support potential revenues of €240,000–€300,000 per MW per year (approximately $260,000–$325,000 per MW-year). This project is expected to bring incremental revenues to Nuvve during the second quarter of 2026 after the first batteries become operational.

"The partnership represents a significant revenue opportunity spread across a pipeline exceeding 1GW, positioning Nuvve as a leading global provider of grid-scale energy storage," said Gregory Poilasne, CEO of Nuvve. "Nuvve continues to build a high-quality portfolio designed to deliver long-term, recurring value through asset ownership, asset management, and exclusive development rights."

Nuvve will serve as the owner and asset manager for the facility and provide full market access services to optimize revenue generation and grid participation. The acquisition strengthens Nuvve's position in the rapidly growing Nordic energy storage market and reinforces its long-term strategy of deploying scalable, revenue-generating infrastructure.

This transaction aligns with Nuvve's broader strategy to expand its global energy storage and grid services platform by leveraging long-term contracts, advanced software, and market optimization capabilities to deliver sustainable growth.

Nuvve also secured exclusive rights to support and deploy battery energy storage projects developed through exiting partnerships that OMNIA Global established. Nuvve also has a Right of First Refusal to acquire ownership stakes in future deployments within this pipeline.

"We see Nuvve as a uniquely fitting partner to efficiently project manage and execute the roll-out of our pipeline utilizing Nuvve's unique load balancing software and years of experience in BESS from the early days of the market. The European market has high arbitrage opportunities for fast movers and with the partnership of Nuvve we have found a partner that efficiently and comfortably can look at a large scale roll out with the most experienced team of its sector," said Daniel Hansen, CEO and Chairman of OMNIA Global.
