Utility Outage

Threat in Infrastructure, arrives with intent

A cascading lifeline failure, power, water, fuel, telecom or the control systems behind them, that disables heating, cooling, medical devices and 911 together.

Includes: Electric Power Outage, Telecommunications Failure / Internet Outage, Fuel Shortage / Supply Disruption, Operational Technology / Industrial Control System Attack, Water System Contamination or Failure

  • Electric Power Outage. A cascading lifeline failure that disables water, heating, cooling, medical devices and communications together.
  • Telecommunications Failure / Internet Outage. A lifeline failure that cuts off 911, alerts and coordination at exactly the moment every other response depends on them.
  • Fuel Shortage / Supply Disruption. A supply-chain hazard that ripples into transportation, generators and emergency operations when fuel stops arriving.
  • Operational Technology / Industrial Control System Attack. A cyber-physical threat to the control systems that run water, wastewater, power and traffic, where a digital intrusion has physical consequences.
  • Water System Contamination or Failure. A lifeline hazard where drinking water becomes unsafe or unavailable, forcing advisories and emergency distribution.

Plans also call it: utility disruption, utility disruptions, utility failure, utility interruption, loss of utilities

Utility Outage

Threat in Infrastructure, on the established threats & hazards list

Impact
5432112345

Likelihood

Likelihood
4

Likely — Expected within the decade — roughly once in 1 to 10 years (10–100% chance in any year).

Impact
4

Major — Severe effects — casualties possible, serious damage across a significant share of the jurisdiction, essential services disrupted for weeks, outside assistance needed.

Readiness
2

Low — Some elements of capability are in place, but important gaps remain that could significantly limit the organization's ability to perform effectively. Additional development is needed before the capability can be relied upon.

The national record

FEMA’s National Risk Index doesn’t model Utility Outage. Your team fills it with local evidence, and Hazzard shows the gap rather than a zero.

How it maps

The same hazard in the vocabularies your plan and FEMA already use.

How it connects

The national record

What the federal data says about Utility Outage: nothing yet

No federal dataset scores Utility Outage or files declarations under it. That's common for threats and emerging hazards, and it's why a brief for Utility Outage is built from your own plans, exercises and records. Hazzard shows the gap instead of inventing a number.

In your plan

What a Utility Outage profile needs, and where each part comes from

A local hazard mitigation plan profiles each hazard the same way (44 CFR 201.6). Here is how Hazzard fills each part for Utility Outage.

  1. Location

    44 CFR 201.6(c)(2)(i)

    Your documents

    No national layer maps Utility Outage. We draw the geographic extent from your plans, studies and annexes, cited to the page.

  2. Extent

    44 CFR 201.6(c)(2)(i)

    Your documents

    The magnitude your plans use for Utility Outage (a scale, a depth, an acreage, a duration), read from your documents and cited, so the profile states the strength you plan for.

  3. Previous occurrences

    44 CFR 201.6(c)(2)(i)

    Your documents

    FEMA files no declaration type for Utility Outage. The history comes from your after-action reports, incident records and plans.

  4. Probability of future events

    44 CFR 201.6(c)(2)(i)

    Your team decides

    No national dataset gives a frequency for Utility Outage. Your team scores likelihood on your scale from the evidence we organize.

  5. Vulnerability and impacts

    44 CFR 201.6(c)(2)(ii)

    Your documents

    The Census population profile and HHS emPOWER counts for context; the consequences themselves come from your plans and exercises.

  6. The assessment itself

    Your team decides

    Likelihood, impact and readiness for Utility Outage are drafted with every source attached, and a person on your team accepts each one. Hazzard never records a score on its own.

How we can help

How we’d help you prepare for Utility Outage

  1. 1

    We pull who depends on it

    HHS emPOWER counts of electricity-dependent residents and the Census profile of your county, gathered before we meet.

  2. 2

    We read your continuity plans

    Your EOP, continuity and mass-care material, so what they say about Utility Outage is cited and the gaps are visible.

  3. 3

    You leave with a cited brief

    Likelihood, impact and readiness for Utility Outage on your own scale, with each figure tied to its source. It is ready for your planning team or council.
