Critical & Backup Power

Critical & Backup Power, engineered as part of one environment.

Critical & Backup Power brings UPS & Critical Power, Power Backup, Battery Energy Storage together around a clear operational brief. Identify essential loads, allowable interruption and required autonomy.

The challenge

Critical loads need an explicitly defined ride-through or backup arrangement, with realistic autonomy, protection and maintenance assumptions.

Our approach

  1. 01Identify essential loads, allowable interruption and required autonomy.
  2. 02Coordinate UPS, storage, backup source, distribution and protection architecture.
  3. 03Define transfer, alarm, load-shedding and restoration behavior.
  4. 04Test operating modes and provide safe isolation and maintenance guidance.

System architecture

How it fits together.

Layer 01

UPS & Critical Power

UPS & Critical Power contributes generation, storage, charging or protected supply according to the load and operating model for critical & backup power.

Layer 02

Power Backup

Power Backup contributes generation, storage, charging or protected supply according to the load and operating model for critical & backup power.

Layer 03

Battery Energy Storage

Battery Energy Storage contributes generation, storage, charging or protected supply according to the load and operating model for critical & backup power.

Layer 04

Integration boundary

Define interfaces between critical & backup power, its connected systems and the owner's existing environment.

The critical & backup power scope connects UPS & Critical Power, Power Backup, Battery Energy Storage through agreed interfaces, network and power dependencies, operating roles and commissioning criteria. Final system selection and interfaces are confirmed against project requirements.
