Eclipse, a European platform that develops, operates, and optimizes battery energy storage systems, has raised €20 million (~$23 million) in a Series A financing round to expand battery storage deployment across Europe.

The round was co-led by BNP Paribas and Noria, with participation from Eclipse’s existing investors, including Wind Capital.

The company said the capital will support three priorities: deploying its first proprietary battery storage projects, continuing the development of Flowstream, and expanding long-term offtake solutions across Europe.

Flowstream is Eclipse’s proprietary optimization and trading platform, designed to optimize storage assets in real time across European electricity markets.

Christophe Guillaume, Co-founder of Noria, said: “We have been convinced by Eclipse’s positioning in the European battery storage market, built around a secured pipeline, a highly differentiated proprietary technology platform, and an integrated model combining development, financing, and optimization, notably for third-party assets. We are pleased to support Eclipse, together with the unique partnership established with BNP Paribas, in its ambition to become a leading specialized player in BESS optimization across Europe.”

The capital raise follows a strategic partnership announced earlier in 2026 between Eclipse and BNP Paribas. Under the partnership, the companies plan to jointly offer long-term offtake solutions that combine Eclipse’s optimization and energy market capabilities with BNP Paribas’ financing, structuring, and credit capabilities.

VC funding raised by energy storage companies in Q1 2026 increased 9% YoY, with $1.2 billion in 26 deals compared to $1.1 billion in 18 deals in Q1 2025, and a 44% increase in deal count, according to Mercom’s Q1 2026 Funding and M&A for Energy Storage report.

In October 2025, enspired, an optimizer for battery energy storage systems, extended its Series B funding over €40 million (~$47 million), with participation from new investor Future Energy Ventures. The round also includes renewed commitments from Zouk Capital, EnBW New Ventures, Banpu NEXT, PUSH VC, and 360 Capital.
