Battery storage looks simple – a steel box that charges when prices are low and discharges when they’re high. But financing a BESS project in Europe means underwriting a trading position: convex revenues, volatile returns, and a growing menu of contractual choices that each shift the risk profile in a different direction.Lisa McDermott, Managing Director and Head of Energy Transition Project Financing at ABN AMRO, has been structuring BESS deals across Europe since 2020. In this episode, she opens up the credit committee. What gets a project over the line, and what quietly stops it.Covered:- Why battery storage finance is fundamentally different from solar or wind and why contracting it away doesn’t change the underlying risk when the contract ends.- From physical tolls to day-ahead swaps, Lisa breaks down which offtake structures are gaining traction in Europe and why the day-ahead swap is the hardest to bank.- Too much merchant exposure, insufficient sponsor equity, weak technical track record and why pushing too many levers at once is the fastest way to stop a deal.- How battery warranties have evolved from 8 to 20 years and why coverage beyond the debt tenor is a bankability requirement, not a nice-to-have.- Germany’s grid fee reform has created financing uncertainty at COD, while the Netherlands’ congestion model is, counter-intuitively, better for bankability.Want to model battery revenue stacks or stress-test tolling structures for a specific market?
