Beyond Thermal Runaway: What Makes Battery Energy Storage Systems Insurable?

As battery energy storage systems (BESSs) continue to expand across the energy sector, insurers, developers, and operators are working to better understand the risks associated with rapid deployment. In this episode of The Edge of Risk podcast, recorded live at the 2026 IRMI Energy Risk & Insurance Conference, Joel Appelbaum welcomes Jen Aitchison, renewable and sustainability practice leader at HUB International, to discuss the factors shaping BESS's risks today. Their conversation goes beyond thermal runaway to examine transportation exposures, business interruption concerns, balance-of-system risks, large-scale fire testing, warranties, and the growing influence of industry codes and standards. They also explore evolving underwriting practices, emerging technologies, and risk management strategies that support the long-term growth and insurability of energy storage. Tune in for an informative look into the intersection of renewable energy innovation, risk management, and insurance.
