What specific role does a backup generator serve during emergencies?

A backup generator plays a crucial role during emergencies by providing power when the main electrical supply is interrupted. This function is vital in various scenarios, such as natural disasters, power outages, or other situations that can disrupt the regular electrical grid. The backup generator ensures that essential services remain operational, allowing facilities like hospitals, emergency response centers, and critical infrastructure to continue functioning.

While other functions like charging emergency communication devices, running heating and cooling systems, or ensuring water supply systems are operational can be supported by a backup generator, their primary purpose is to serve as an alternative power source during outages. This enables continuity of operations and helps to maintain safety and security during emergencies.
