Power redundancy

Power redundancy: The use of multiple power sources, backup generators, and other measures to ensure that critical systems and equipment can continue to operate in the event of a power outage or other disruption. This concept is used in various industries, including data centers, hospitals, and telecommunications, to prevent downtime and maintain service availability. Examples include uninterruptible power supply (UPS) systems, dual-power feeds, and on-site generation.
