Eclipse Partners with BNP Paribas to Fuel Next Growth Phase
Eclipse, a leading battery storage developer, owner, operator, and energy trading specialist, has entered into a landmark strategic partnership with BNP Paribas, one of the largest banking groups in the Eurozone, to accelerate the deployment of Battery Energy Storage Systems (BESS) across Europe. The collaboration marks a significant step forward in strengthening Europe’s energy resilience and supporting the continent’s transition to a more flexible, low-carbon electricity system. As part of the agreement, BNP Paribas will make a strategic equity investment in Eclipse, reinforcing the company’s growth ambitions and enhancing its ability to scale projects across key European markets.
The partnership brings together complementary strengths. Eclipse has built a fully integrated business model that spans the entire BESS value chain—from project development and ownership to operations and advanced real-time energy trading. BNP Paribas contributes deep financial expertise, structuring capabilities, and more than two decades of experience in European physical and financial power markets. Together, the two organizations aim to create innovative financing and revenue solutions that unlock the full value of battery storage assets while reducing risk and lowering the cost of capital for project owners.
At the heart of Eclipse’s competitive advantage is its proprietary algorithmic trading platform, Flowstream. This state-of-the-art software enables real-time optimization of battery storage assets in wholesale electricity markets. Flowstream continuously analyzes price signals, grid conditions, and market volatility to determine the most profitable and system-supportive operating strategies. By optimizing charge and discharge cycles, the platform maximizes revenue streams from energy arbitrage, balancing services, and ancillary markets, while also supporting grid stability.
Unlike many market participants that focus exclusively on development or trading, Eclipse operates as a fully integrated BESS player. The company develops, owns, and operates industrial-scale battery storage facilities while also providing optimization services for third-party assets. This dual capability gives Eclipse a granular understanding of asset performance, regulatory frameworks, and market dynamics. It also allows the company to structure projects and revenue strategies that are aligned with evolving market conditions.
Eclipse’s development pipeline reflects its strong position in the sector. The company currently manages 16 projects across France and Belgium, representing a combined capacity of approximately 850 megawatts (MW). These projects are designed to provide critical flexibility to power grids increasingly dominated by renewable generation such as wind and solar. As renewable penetration rises, so does the need for storage solutions capable of balancing supply and demand in real time, mitigating curtailment, and ensuring system reliability during periods of volatility.
BNP Paribas’ strategic equity investment underscores confidence in Eclipse’s business model and growth trajectory. Beyond capital support, the bank will work alongside Eclipse to provide tailored financing solutions for battery storage projects. This includes structured debt financing, innovative hedging instruments, and long-term offtake arrangements designed to manage merchant exposure and stabilize project revenues.
Merchant risk remains one of the key challenges facing BESS developers. Unlike traditional generation assets that may benefit from long-term power purchase agreements (PPAs) or regulated returns, battery storage revenues are often linked to dynamic wholesale markets. While this volatility can create attractive upside opportunities, it also introduces uncertainty that can complicate project financing. Through this partnership, Eclipse and BNP Paribas aim to mitigate these risks by offering sophisticated hedging structures and credit-backed offtake solutions.
By leveraging BNP Paribas’ strong credit profile and structuring expertise, the partnership can provide long-term revenue contracts that enhance bankability. At the same time, Eclipse’s advanced trading and optimization capabilities ensure that storage assets are operated to capture maximum market value. This combination is expected to reduce asset-level cost of capital and accelerate project deployment timelines.
Augustin Derville, Co-founder and CEO of Eclipse, emphasized the strategic significance of the collaboration. He noted that Eclipse has developed unmatched expertise across the BESS value chain, blending project development capabilities with grid-scale optimization know-how. According to Derville, this integrated model provides unique insight into power market behavior and evolving system needs. The partnership with BNP Paribas will enable Eclipse to deliver long-term revenue solutions to clients while securing robust financing structures that support the rapid expansion of battery storage across Europe.
From BNP Paribas’ perspective, the partnership aligns closely with its broader sustainability and energy transition strategy. Olivier Osty, Deputy COO of BNP Paribas Group and CEO of BNP Paribas Corporate & Institutional Banking (CIB), described the collaboration as an innovative step toward building a more resilient and flexible European energy infrastructure. By combining industrial-scale battery expertise with financial structuring capabilities, the two companies are positioned to develop solutions that enhance market efficiency, improve system flexibility, and contribute to sustainability objectives.
The timing of the partnership reflects broader shifts in the global energy landscape. Electricity demand is increasing steadily, driven by the electrification of transport, heating, and industrial processes. Electric vehicles, heat pumps, data centers, and digital infrastructure are placing new demands on power systems. At the same time, renewable energy is expected to meet nearly all incremental electricity demand in the coming decades. Projections suggest that electricity could account for approximately half of global final energy consumption by mid-century.
This transformation requires more than additional renewable generation capacity. It demands flexible infrastructure capable of managing intermittency, balancing grids in real time, and ensuring reliability under increasingly complex operating conditions. Battery energy storage systems are emerging as a cornerstone technology in this new paradigm. They provide fast-response balancing services, support frequency regulation, enable peak shaving, and reduce reliance on fossil-fuel-based peaking plants.
Europe, in particular, faces both opportunity and urgency. The continent’s ambitious decarbonization targets, combined with its drive for greater strategic autonomy and energy security, are accelerating investment in clean energy infrastructure. Power markets across the European Union are evolving to accommodate higher shares of renewables and distributed generation. However, scaling storage deployment requires innovative financing models and risk management frameworks that can adapt to market volatility and regulatory complexity.
The Eclipse–BNP Paribas partnership is designed to address precisely these challenges. By aligning technical optimization capabilities with financial engineering expertise, the two organizations can create comprehensive solutions for utilities, independent power producers (IPPs), and corporate energy consumers. These stakeholders increasingly seek storage-backed solutions that provide price stability, flexibility, and resilience in an uncertain energy environment.
Moreover, the collaboration reinforces Europe’s broader objectives of enhancing energy security and supporting industrial competitiveness. By accelerating BESS deployment, the partnership contributes to a more decentralized and resilient grid architecture. Storage assets located close to demand centers can alleviate congestion, reduce transmission losses, and enhance local system reliability.
As Europe continues to navigate the energy transition, partnerships that integrate technology innovation with financial sophistication will play a decisive role. Eclipse and BNP Paribas are positioning themselves at the forefront of this evolution. Through equity investment, tailored financing, advanced trading solutions, and long-term revenue structures, the partnership aims to unlock new opportunities in battery storage while supporting Europe’s journey toward a secure, sustainable, and flexible energy future.
With a robust pipeline, advanced optimization technology, and the backing of one of Europe’s leading financial institutions, Eclipse is well-equipped to scale its operations and expand its footprint. For BNP Paribas, the collaboration represents a strategic investment in the infrastructure that will underpin Europe’s next generation of energy markets. Together, the two organizations are charting a path that blends innovation, resilience, and financial strength—key ingredients for powering Europe’s energy transition in the decades ahead.
