Eclipse, a prominent developer and operator of Battery Energy Storage Systems (BESS), has entered into a strategic partnership with global banking giant BNP Paribas, aimed at accelerating the rollout of large-scale battery storage infrastructure across European markets. As part of the agreement, BNP Paribas will also make a strategic equity investment in Eclipse, reinforcing its commitment to support energy transition technologies.
The collaboration is designed to strengthen Europe’s energy resilience by increasing the deployment of battery storage projects that can store renewable power when generation is high and release it during peak demand periods. Eclipse brings to the table its integrated BESS capabilities — from project development to real-time optimisation — while BNP Paribas contributes deep financial sector expertise and structuring strength.
Eclipse’s proprietary algorithmic trading platform, Flowstream, plays a central role in the partnership by optimising storage performance across both the company’s own portfolio and third-party assets. The company currently manages a pipeline of 16 industrial-scale battery storage projects in France and Belgium, totalling approximately 850 megawatts of capacity in development.
Under the terms of the partnership, BNP Paribas will offer customised financing solutions for BESS projects to asset owners. These solutions include hedging tools designed to help manage merchant risk and reduce capital costs at the asset level, making large battery storage investments more attractive and financially viable in a competitive market.
In addition, the two organisations will work together to offer long-term offtake arrangements, combining Eclipse’s technical expertise with the bank’s credit credentials. This combined approach is expected to open up new avenues for investors and developers looking to participate in the rapidly expanding battery storage sector.
Leaders from both companies emphasised their shared vision of boosting Europe’s energy infrastructure. Eclipse’s co-founder said the partnership would enable more robust financing and revenue solutions for clients, while BNP Paribas executives highlighted the collaboration’s potential to enhance market flexibility and contribute to broader European objectives for energy resilience and sustainability.
