Backup power systems

Definition

Backup power systems are alternative energy sources that provide electricity when the primary power source fails or is unavailable. These systems are crucial for maintaining essential services and operations during power outages, ensuring resilience in critical infrastructure like hospitals, data centers, and emergency services. They can vary in type and scale, from small generators to large battery storage systems, and play a vital role in overall building safety and functionality.
