Planning Guide

Data Center Standby Power Planning

A requirements checklist for resilience architecture, load steps, controls, fuel autonomy, testing and maintainability in critical standby systems.

Key Takeaways

  • Translate the resilience target into an electrical operating architecture
  • Model UPS, cooling and motor load steps
  • Design testing and maintenance access into the system from the start

Technical guide introduction

A data-center generator plant is defined by the required recovery behavior and maintainability as much as by installed capacity. Utility failure, partial failure, maintenance and black-building scenarios should all be represented.
