Eclipse, a top company in battery storage development and energy trading, has teamed up with BNP Paribas, one of the biggest banks in the Eurozone, to speed up the spread of Battery Energy Storage Systems (BESS) across Europe. BNP Paribas will make a strategic equity investment in Eclipse as part of the deal.
Strengthening Europe’s Energy Resilience
The goal of the partnership is to help big battery storage projects grow and make Europe’s energy supply more secure. Eclipse is an integrated BESS player that builds, owns, and runs energy assets on an industrial scale. The company has 16 projects in France and Belgium that are in the works and will have a total capacity of 850 MW.
Through its proprietary algorithmic trading platform, Flowstream, Eclipse optimizes battery storage assets in real time for both its own portfolio and third-party assets. This capability allows the company to maximize asset performance and respond quickly to market changes.
Financing and Risk Management Solutions
Under the partnership, BNP Paribas will provide tailored financing solutions for BESS projects, along with hedging instruments to help manage merchant risk and lower the cost of capital at the asset level.
Together, Eclipse and BNP Paribas will offer long-term offtake solutions by combining the bank’s credit strength and structuring expertise with Eclipse’s advanced optimization and continuous trading capabilities. The partnership builds on BNP Paribas’ more than 20 years of experience in European physical and financial power markets.
Augustin Derville, Co-founder & CEO, Eclipse, said: “Eclipse has developed unmatched expertise across the Battery Energy Storage System value chain, combining project development with grid-scale optimization capabilities. This dual business model gives us a unique understanding of market dynamics. The partnership with BNP Paribas will enable us to deliver long-term revenue solutions to our clients, and robust asset financing to support the growth of battery storage across Europe.”
Olivier Osty, Deputy COO, BNP Paribas Group and CEO, BNP Paribas CIB, stated: “This innovative partnership between BNP Paribas and Eclipse reflects our shared commitment to building a more resilient energy infrastructure for Europe. By combining Eclipse’s expertise in industrial-scale battery storage with BNP Paribas’ financial and structuring capabilities, we are developing solutions that enhance market flexibility, efficiency, and sustainability, helping utilities, IPPs, and corporates navigate the transition while contributing to the EU’s broader objectives of energy resilience and strategic autonomy.”
Supporting the Energy Transition
Renewable energy is expected to meet almost all of the new demand for electricity in the coming decades. This is because electrification and population growth are making the demand for electricity go up. The partnership puts both companies in a good position to help pay for new energy assets, which will help Europe move toward a power system that is safer, more flexible, and more sustainable.
