Eclipse has secured €20 million in Series A funding to support the expansion of battery energy storage deployment and long-term offtake solutions across Europe. The financing round was co-led by BNP Paribas and Noria, with continued backing from existing investors including Wind Capital. The investment marks a significant step for the Paris-based company as demand for flexible power infrastructure accelerates across European electricity markets.
Funding to Scale Battery Storage Across Europe
The new capital will be directed toward three core areas of growth for Eclipse. These include the development of its first proprietary battery storage projects, further enhancement of its in-house optimization platform Flowstream, and the expansion of long-term offtake solutions for asset owners. By combining infrastructure development with advanced market optimization, Eclipse aims to strengthen its position in the rapidly evolving battery energy storage systems sector.
Battery storage is becoming increasingly important as Europe integrates more renewable energy into its power grids. Storage assets help stabilize electricity systems by balancing supply and demand, absorbing excess generation, and releasing power when needed. Eclipse’s model is designed to address this growing need by offering both owned storage assets and services for third-party battery storage operators.
Flowstream Platform at the Center of Expansion
A central part of Eclipse’s strategy is Flowstream, its proprietary optimization and trading platform for battery energy storage assets. The platform enables real-time optimization across European electricity markets, helping storage asset owners maximize operational and financial performance. With the Series A funding, Eclipse plans to broaden the adoption of Flowstream among battery storage owners across the continent.
The company’s integrated approach combines technology, trading expertise, route-to-market services, and infrastructure development. This positions Eclipse to support projects from development through financing, operation, and optimization. For asset owners and lenders, the company aims to provide more bankable revenue structures in a market where long-term visibility remains a key challenge.
Strategic Partnership With BNP Paribas
The financing follows a strategic partnership announced earlier this year between Eclipse and BNP Paribas. The partnership is intended to support the financing and deployment of battery energy storage systems across Europe. Together, the two companies plan to offer long-term offtake solutions that combine Eclipse’s storage optimization expertise with BNP Paribas’ financing, structuring, and credit capabilities.
Augustin Derville, Co-founder and CEO of Eclipse, described the funding round as a defining milestone for the company. He said Eclipse has built the team, technology platform, and partnerships needed to become a leading European platform for battery storage optimization, infrastructure development, and long-term offtake solutions. He added that the company is now well placed to support the next generation of utility-scale battery storage projects across Europe.
Investor Confidence in Eclipse’s Model
BNP Paribas said the partnership reflects a shared belief that battery storage and flexibility solutions will play a central role in transforming European power markets. Olivier Osty, Deputy COO of BNP Paribas Group and CEO of BNP Paribas Corporate and Institutional Banking, said storage infrastructure will be important for the energy transition and Europe’s energy security. He added that combining Eclipse’s development and optimization capabilities with BNP Paribas’ financing expertise could help support scalable and bankable flexibility infrastructure.
Noria also highlighted Eclipse’s positioning in the European battery storage market. Christophe Guillaume, Co-founder of Noria, pointed to the company’s secured pipeline, differentiated technology platform, and integrated model covering development, financing, and optimization. He said Noria was pleased to support Eclipse alongside BNP Paribas as the company works to become a leading specialized player in battery energy storage optimization across Europe.
The €20 million Series A round gives Eclipse additional resources to expand its technology platform, deploy its own battery storage projects, and serve third-party asset owners. As European electricity markets place greater value on flexibility, companies that can combine storage infrastructure with optimization and long-term revenue solutions are becoming increasingly relevant. Eclipse’s latest financing and partnership with BNP Paribas position the company to play a larger role in Europe’s battery storage and energy transition landscape.
