Eclipse, a battery storage development and energy trading company, has entered into a strategic partnership with BNP Paribas, to accelerate the deployment of Battery Energy Storage Systems (BESS) and strengthen Europe’s energy resilience. The agreement includes a strategic equity investment by BNP Paribas in Eclipse.
Eclipse operates as an integrated BESS player, developing, owning and operating industrial-scale energy assets. Through its proprietary algorithmic trading platform, Flowstream, the company optimises battery storage assets in real time across both its own portfolio and third-party projects. Eclipse currently has a development pipeline of 16 projects in France and Belgium, representing a combined capacity of 850 MW.
Under the partnership, BNP Paribas will provide tailored financing solutions for BESS projects, alongside hedging instruments designed to manage merchant risk and lower asset-level cost of capital. The two organisations will jointly offer long-term offtake solutions, combining BNP Paribas’ credit strength and structuring expertise with Eclipse’s optimisation and continuous trading capabilities to support the financing and scaling of battery storage infrastructure.
Augustin Derville, Co-founder and Chief Executive Officer of Eclipse, said the company had developed deep expertise across the battery storage value chain by integrating project development with grid-scale optimisation. “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,” he said.
Olivier Osty, Deputy Chief Operating Officer of BNP Paribas Group and Chief Executive Officer of BNP Paribas CIB, described the collaboration as a reflection of the two companies’ shared commitment to strengthening Europe’s energy infrastructure. By combining Eclipse’s industrial-scale storage expertise with BNP Paribas’ financial and structuring capabilities, he said, the partnership would enhance market flexibility, efficiency and sustainability, while supporting the EU’s objectives of energy resilience and strategic autonomy.
