"DATA CENTERS LIVE ON POWER, AND THEY NEED GENERATOR TO ENSURE 24 HOURS"

A technology trend is taking place that is increasing reliability and scalability of emergency power systems for data centers. Almost all major generator manufacturers have recently developed controls for their generators that allow them to parallel with each other without needing complex and costly paralleling switchgear. This advancement in controls has allowed smaller, more readily available generators to provide more redundancy and scalability than larger engine generator sets.

By adding generators modularly, sites can install what they need when they need it. Smaller generators are also easier to move to remedy constrained capacity issues. Some generator manufacturers include the switching on the generator also, making changes to the one-line faster and reduces risks.

The Backup Power Generator or Genset will kick in to supply essential power to the Data Centre during a power blackout. The Genset can be designed for N+1 redundancy. Each Genset should have enough capacity to support the entire load of the Data Centre including support equipment such as PAC and network equipment. 


A storage tank located near the Gensets will store and supply diesel fuel to the Gensets. The Gensets should be configured such that they can be taken off line and regularly tested without disruption to the power supply.
