BNP Paribas and Eclipse Form Battery Storage Partnership Across Europe

BNP Paribas and UK-based energy storage company Eclipse have announced a strategic partnership, including an equity investment by BNP Paribas in Eclipse, to accelerate deployment of battery energy storage systems across Europe. The collaboration will combine BNP Paribas's financial structuring capabilities with Eclipse's grid-scale optimization expertise to offer tailored financing and hedging solutions for BESS projects.

Founded in 2022, Eclipse Power builds and operates utility-scale battery storage projects that stabilize electric grids, support renewable energy integration, and increase power system flexibility. Under the new partnership, the two companies will provide asset owners with customized financing solutions for BESS projects alongside hedging instruments designed to manage merchant risk and reduce asset-level cost of capital. The collaboration will also enable them to offer long-term offtake solutions, bringing together BNP Paribas's credit and structuring capabilities with Eclipse's continuous trading expertise.

Large-scale BESS systems store surplus renewable power and release it during peak demand, improving grid reliability and reducing dependence on fossil fuel generation. As Europe advances its renewable energy targets, battery storage has become an increasingly critical infrastructure layer. The BNP Paribas–Eclipse partnership reflects growing recognition by major financial institutions that private capital must underpin the build-out of storage capacity needed to make intermittent renewables dispatchable. The deal also aligns with EU objectives of energy resilience and strategic autonomy.

The partnership positions BNP Paribas as a more active player in the physical energy transition beyond traditional green bond and sustainable finance offerings. For Eclipse, the equity investment and long-term financing access from a major European bank accelerates its project pipeline across multiple markets. As battery storage costs continue to fall and regulatory frameworks for energy storage mature across EU member states, the partnership is structured to scale. Broader demand for BESS across utilities, independent power producers, and corporates is expected to grow significantly through the end of the decade.
