PE-11 Emergency Power
Provide an uninterruptible power supply to facilitate Selection: an orderly shutdown of the system; transition of the system to long-term alternate power in the event of a primary power source loss.
Source: NIST SP 800-53 Rev 5, PE-11. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open NIST SP 800-53 Rev 5 in the compliance library.
Base controls and their enhancements. Which apply follows the baseline you are assessed against (for example FedRAMP Moderate or High, or the low, moderate and high baselines of SP 800-53B). Text in square brackets is a parameter your organisation sets.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- No uninterruptible power supply supports orderly shutdown or transition to alternate power for the system
- UPS capacity and battery runtime have not been tested to confirm they support the selected shutdown or transition
