"Energy storage systems are heavily regulated, require expensive testing and certification, mandate multiple layers of active protection systems, and require active or passive protection mechanisms when deployed in the field. Beyond that, best practices, local regulations mandate emergency response planning, training for the fire department, and the 24/7 availability of subject matter experts (SMEs) to support local fire service response. This process drastically improves safety and the ability of first responders to manage an incident appropriately."
