Envision completes industry's largest 64MWh fire test as mandatory testing kicks in
What happened
Envision Energy completed a 64MWh station-level fire test—the largest in the industry—using a system with over 700Ah cells across four cabinets spaced 5cm apart. During the test, open flames burned for 9 hours before self-extinguishing, while temperatures in adjacent cabinet cells remained below 50°C. Multiple energy storage fire and explosion incidents in 2026—including a 21.6MW solar-storage plant in Canada's Prince Edward Island and a facility in Southern California—accelerated regulatory changes. UL9540A 6th edition and NFPA 855 2026 edition have upgraded large-scale fire testing from a scoring bonus to a mandatory certification requirement for energy storage systems to enter the market.
