Nuvve Announces Third European BESS Project in Weeks, Crossing 150 MW of Combined Capacity Under OMNIA Global Partnership

60 MW Romania project brings Nuvve's announced European BESS portfolio to more than 150 MW across three countries in under two weeks; annual fee revenue potential ranges from $250,000 to $500,000 per MW, with a right of first refusal to acquire each asset

Nuvve Holding Corp. (NASDAQ:NVVE), a global leader in vehicle-to-grid (V2G) technology and grid-interactive energy solutions, today announced it has extended its strategic cooperation with OMNIA Global (Zug, Switzerland) to include a 60 MW / 120 MWh standalone battery energy storage system (BESS) in Braşov, Romania — the third major European project activated under the companies' cooperation agreement in less than two weeks.

The Romanian project, developed through SPV Braşov 60, brings Nuvve's total announced European BESS capacity under the OMNIA Global partnership to more than 150 MW — comprising 50 MW in Sweden, 40 MW in Austria, and now 60 MW in Romania — with commercial operations across all three assets targeted to begin in 2026. Including Nuvve's existing battery and V2G projects, the company's combined energy storage platform now exceeds 150 MW across multiple geographies.

Three Countries, Three Projects, Under Two Weeks

The pace of execution under the OMNIA Global cooperation agreement is a direct reflection of the pipeline maturity OMNIA Global brought to the partnership. When Nuvve and OMNIA Global announced their broad strategic cooperation earlier this month — establishing a framework for pipeline access, grid aggregation, and right of first refusal across OMNIA Global's European portfolio — OMNIA Global's development pipeline already comprised more than 700 MW across 16 projects in Austria, Romania, and Bulgaria, at various stages of development and due diligence. The speed at which individual assets are planned to be activated into the Nuvve commercial platform reflects that readiness.

The three announced projects to date — Sweden, Austria, and Romania — share a common commercial profile: contracted EPC agreements, secured site and grid access rights, and commercial operation dates planned for 2026.

Revenue Per MW: A High-Margin Fee Model Across Markets

Nuvve's potential revenue across its European BESS platform scales directly with the generation and dispatch performance of each project. Across the announced portfolio, Nuvve's revenue potential ranges from approximately $250,000 per MW per year in markets with established ancillary service pricing, to as high as $500,000 per MW per year in higher-yield markets such as Romania, where grid balancing service premiums remain elevated relative to Western European benchmarks.

With a potential revenue scaling at a very fast path considering the deployments underway, Nuvve's GIVe™ platform will soon be leveraged in its full capacity, managing grid aggregation and dispatch optimization across each project's local ancillary service and wholesale energy markets.

About SPV Braşov 60

The Braşov project is a 60 MW / 120 MWh standalone BESS positioned to serve Romanian balancing and ancillary service markets, with commercial operation targeted for Q4 2026. Key project attributes:

• Capacity: 60 MW / 120 MWh standalone BESS
• Location: Braşov, Romania — a high-demand grid node within the Romanian national transmission network
• Planned Commercial Operation Date: Q4 2026
• Development Status: Binding offer submitted; project advancing toward ready-to-build
• Market Context: Romania's balancing and ancillary service markets offer among the highest per-MW revenue yields in continental Europe, driven by accelerating renewable penetration and grid stabilization requirements
• Revenue Optimization: Managed by Nuvve's GIVe™ platform across Romanian FCR, aFRR, and balancing market mechanisms
• Nuvve Commercial Rights: Consulting fee, 9% grid aggregation fee on all project revenues, and right of first refusal to acquire the completed asset

Leadership Perspectives

"Three projects, three countries, more than 150 MW — in under two weeks. That is the pace we committed to when we entered into the OMNIA Global cooperation agreement, and that is the pace we are delivering. What matters here is not just the scale — it is the economics. At $250,000 to $500,000 of revenue per MW per year, Nuvve is building a European energy platform that generates high-margin recurring revenue from day one of operation. Romania is an especially compelling market given its yield profile, and we expect it to be one of the strongest contributors to our European fee revenue base."

— Gregory Poilasne, Co-Founder & Chief Executive Officer, Nuvve Holding Corp.

"Our pipeline exists because we prioritise the development work — securing grid access, completing due diligence, signing EPC contracts — before any asset is brought to a partner. The Braşov project is the third demonstration of that in two weeks. Romania is a market we know deeply, and the revenue dynamics there are exceptional for grid-scale storage operators. Nuvve is going to revenue on a 150 MW European platform, with an expanding pipeline behind it."

— Daniel Hansen, CEO, OMNIA Global
