Eclipse Raises €20M for Battery Storage Market Platform

Eclipse, a nascent player in energy storage optimization, has successfully closed a €20 million Series A funding round. The investment, co-led by banking giant BNP Paribas and the investment fund Noria, signals strong confidence in the company's mission to create a more efficient financial market for battery storage assets. This capital infusion follows an earlier €5.5 million seed round, which included participation from Wind Capital.

Founded in 2023 by Augustin Derville, a former co-founder of electric vehicle charging network Electra, Eclipse aims to tackle the inherent intermittency of renewable energy sources. The company's proprietary technology platform, Flowstream, is designed to intelligently manage energy storage. It capitalizes on price fluctuations by purchasing electricity during periods of low demand and low cost, storing it in batteries, and then selling it back to the grid when demand and prices surge. This strategy directly addresses the significant issue of wasted energy, with France alone losing approximately 3 TWh in 2025 due to storage limitations, a volume that had doubled year-on-year.

A key differentiator in this funding round is the strategic involvement of BNP Paribas, which is not only an investor but also a crucial offtaker. This partnership provides Eclipse with enhanced credibility and guarantees long-term revenue streams for battery asset owners, a critical factor for securing project financing. Historically, such assurances were primarily offered by large energy conglomerates like Engie, TotalEnergies, and EDF. By integrating BNP Paribas's financial expertise and market access with Eclipse's algorithmic prowess, the venture seeks to make flexibility infrastructure more bankable and scalable across Europe.

Olivier Osty, Deputy CEO of BNP Paribas and CEO of BNP Paribas CIB, highlighted the synergistic nature of the collaboration. "By combining Eclipse's expertise in developing and optimizing storage assets with BNP Paribas's know-how in financing and structuring, we aim to contribute to the emergence of bankable, robust, and large-scale deployable flexibility infrastructure across Europe," he stated. This strategic alliance was initially announced in February 2026, preceding the funding round's closure.

The energy storage market is experiencing significant growth, driven by the increasing penetration of renewables and the need for grid stability. Eclipse currently manages approximately 5% of its 2030 target of 2 gigawatts under management. However, with numerous battery projects reaching maturity and seeking optimization solutions, the company is well-positioned for rapid expansion. Derville noted that a single contract with BNP Paribas could double their managed megawatts, underscoring the potential for swift scaling.

The newly acquired capital will be instrumental in funding Eclipse's own storage projects, further development of the Flowstream platform, and accelerating its offtake solutions across the European continent. The company, which currently employs around twenty individuals, operates in France and Belgium and is actively exploring expansion into markets like Spain. This strategic move by Eclipse, backed by significant financial and strategic partners, marks a pivotal step in monetizing energy storage and supporting the transition to a more resilient and renewable energy future.
