Power Grid & Outages
Power Grid Card Explained
The Power Grid card combines public ISO/RTO operator signals with outage impact context so users can separate grid operating stress from local distribution outages.

Quick answer / What to check next
Quick answer
The Power Grid card combines public ISO/RTO operator signals with outage impact context so users can separate grid operating stress from local distribution outages.
What this signal means
Grid stress and outages can compound heat, cold, storms, wildfire, communications, fuel, and medical-device preparedness concerns.
What to check on HazardNow
status label, active alerts, observed stress, impact, customers tracked, outage share, counties, updated time, and source.

Quick read
- Useful for
- Grid stress and outages can compound heat, cold, storms, wildfire, communications, fuel, and medical-device preparedness concerns.
- Watch
- status label, active alerts, observed stress, impact, customers tracked, outage share, counties, updated time, and source.
- Confirm with
- ISO/RTO public operator notices and ODIN outage data
- Remember
- Utility coverage is incomplete and outage markers are not precise household status. Operator stress does not mean your utility will interrupt service.
How to read this card
- Status: Normal/Advisory/Elevated/Major/Severe/Widespread/Unknown style bucket after normalizing public source context.
- One-line text: either outage share, affected counties/regions, active alerts, or ISO/RTO live context.
- Threshold guide in the hover card: Elevated can be one advisory or multi-region weak stress; Major generally needs two or more advisories or one major-region alert; Severe/Widespread require explicit emergency evidence.
- Updated: source/display timing for the public grid/outage blend.
Hover card metrics explained
- Trigger: the strongest reason for the rating, such as active alerts, inferred stress, or outage impact.
- Active Alerts: explicit operator notices that the card can display when available.
- Observed Stress: inferred operator stress summaries when explicit emergency text is not the only signal.
- Live Regions: how many major grid regions were successfully read in the live refresh path.
- Impact: customer-outage summary when available.
- Customers tracked: denominator used for outage-share context; it may be partial coverage.
- Outage share: customers out divided by tracked customers when the denominator is trusted enough.
- Counties: affected county count where outage data supports it.
- Source: shown as ISO/RTO Live + ODIN in normal hover cards.
What can make this status change?
- An ISO/RTO posts or clears an advisory, conservation request, energy emergency, or load-shed notice.
- Outage counts or affected counties rise or fall.
- Live-region coverage succeeds or fails, changing confidence.
- Weather, heat, cold, wildfire, or fuel constraints create operator stress.
Limitations
Outage coverage is provider-dependent and can be partial. A low outage share does not guarantee a specific address has power, and grid stress does not guarantee distribution outages.
Sources and update behavior
The dashboard summarizes public grid and outage readings. Operator feeds can be live-like but source pages and outage datasets may update at different cadences.

FAQ
Does Major mean my power will go out?
No. It means public grid or outage signals are elevated enough for dashboard context. Your utility and local officials remain authoritative.
