In May 2026, our co-host Laurent Segalen had the privilege of chairing a high-profile panel hosted by SolarPower Europe at its annual Solar Power Summit in Brussels, one of the leading gatherings for the European solar and energy storage sectors.
This episode brings highlights from the hour-long conversation, featuring two distinguished industry leaders: Fredrik Andrén Sandberg from RWE and Hanna Kunzmann from EQT. Between them, their organisations oversee more than 10 GW of battery storage projects either in operation or under development, offering a unique perspective on the realities of financing and scaling storage assets.
The discussion addressed one of the most important questions facing the energy transition today: the bankability of battery storage investments. As battery deployment accelerates across Europe and beyond, investors, developers, and policymakers are increasingly focused on understanding the risks and opportunities that will determine the sector's long-term attractiveness.
The conversation examines battery bankability through four interconnected dimensions. First, technology risk: are batteries still exposed to meaningful technological uncertainty, or have the key challenges shifted towards commercial execution? Second, commercial risk: how should investors evaluate revenue models, merchant exposure, and the growing role of hybridisation strategies? Third, regulatory risk: what policy and market-design uncertainties could affect future returns, from evolving capacity mechanisms to unexpected rule changes? Finally, digital risk: how critical are cybersecurity, battery management systems (BMS), and energy management systems (EMS) in safeguarding performance and protecting asset value over the long term?
The session attracted a packed audience in Brussels and has since been widely praised for the quality, depth, and practical insights of the discussion. Whether you are an investor, developer, policymaker, or simply interested in the future of energy storage, this episode offers a valuable window into how some of the industry's leading players assess risk and opportunity in one of the fastest-growing sectors of the energy transition.
