Geomagnetic Disturbance Monitoring In testing
See storm stress
before it hits your grid.
Pxie provides geomagnetic disturbance monitoring for power grids: it shows which substations and lines a solar storm will push hardest, and tells your operators what to do about it.
Grid storm risk is included from the Builder plan.
Coverage: Modeled anywhere on Earth; most detailed in Alberta and the rest of North America.
Geomagnetic disturbance (GMD) risk, per asset.
Substation geomagnetic risk
A 0 to 100 risk score and a Watch, Warning or Alert level for every substation, as storms push geomagnetically induced current (GIC) into transformers, with a 60-minute outlook.
A GMD operating procedure checklist
Prioritized plain-language actions for each alert level, tailored to the substation and its most exposed line.
Geomagnetic storm alerts for utilities
Webhook alerts when a substation reaches the level you choose.

Who uses it
- Transmission and distribution utilities decide which substations to watch first.
- Grid reliability coordinators coordinate one regional response.
- Large industrial power users plan sensitive operations around storms.
Storm watch: 3 substations elevated

Geomagnetic disturbance monitoring questions.
Is geomagnetic disturbance monitoring ready for operations?
It is in testing. Estimates are modeled and can be inaccurate, so use them to guide attention and planning alongside your own measurements, not as the only basis for an operating decision.
How accurate is the substation geomagnetic risk score?
Scores are modeled estimates on a relative 0 to 100 scale, checked in the field in Alberta, and designed to rank which assets need attention first.
Can it support our GMD operating procedure?
Yes. Each alert level comes with a prioritized action checklist you can align with your own procedure.
Does it help with NERC TPL-007 and EOP-010 work?
Pxie provides documented storm assessments and action lists you can reference in storm-readiness work. It does not certify compliance.
How do geomagnetic storm alerts for utilities work?
Register substations, choose a minimum level, and Pxie sends a webhook when a substation reaches it.
