This week on Energy Unplugged, we’re delighted to welcome Martin Daronnat, Head of Flexibility & Structured Origination at ENGIE . He joins Casimir Lorenz, Aurora’s Managing Director for Central Europe, for a deep dive into the emerging market for flexibility purchase agreements (FPAs) and their role in financing and operating large-scale battery energy storage systems (BESS). Martin has over 10 years of experience in energy, with a strong background in flexibility and renewables structuring and origination. Under his leadership, ENGIE offers flexibility offtake agreements and structured products that make energy assets bankable while optimising risk exposure, including market and credit risk. In 2024, ENGIE closed Germany’s first long-term fixed-price physical FPA, enabling a large-scale BESS project to reach financial close. Main topics include: How flexibility purchase agreements (FPAs) support large-scale battery storage projects and make them bankable. Exploration of the key factors that determine FPA pricing, including technical battery parameters, market and credit risk, and contract terms. How portfolio effects and strategic positioning influence the value of batteries for traders and asset owners. Differences between fixed-price, partial, and merchant FPAs across European markets.
