Complimentary monthly review of European day-ahead and balancing markets reflects energy storage growth in Europe

Nuvve Holding Corp. (NASDAQ:NVVE) ("Nuvve" or the "Company"), a clean-energy technology company specializing in grid-scale battery energy storage and vehicle-to-grid (V2G) solutions, today announced the launch of the European Power Market Brief, a free monthly publication reviewing price trends, market drivers and the near-term outlook across European day-ahead and balancing markets.

The inaugural issue (Issue 01, July 2026) reviews June 2026 and sets out the outlook for July and August. It examines the Nordic hydro situation, a seasonal single price driver, natural gas impacts on energy pricing during low-renewable hours, the influence of solar on midday and negative-price hours as well as commentary on the implications for balancing and dispatch, the markets in which flexible energy-storage assets compete.

Drawing on public data from sources including the ENTSO-E Transparency Platform, EnergiNet, NVE and Open-Meteo, the brief will provide operators, investors, partners and policymakers with a consistent monthly read on the conditions shaping European power prices. It is published as market commentary for information purposes only and does not constitute investment advice, a recommendation, or an offer of any product.

"Europe’s power markets are increasingly where the volatility and the value sit, and that is exactly where Nuvve is focused," said Gregory Poilasne, Co-Founder and Chief Executive Officer of Nuvve. "We wanted to share the same market read we follow internally in a clear, accessible format that anyone tracking the European energy transition can use month to month with an initial focus on the Nordics that will expand over time to the whole of Europe."

The European Power Market Brief will be published monthly. To subscribe or send feedback, contact info@nuvve.com.
