Geomagnetic Risk for Electric Utilities
Put storm context beside every asset.
Geomagnetic risk for electric utilities starts with knowing which assets deserve attention. Pxie combines space weather, ground magnetic observations and modeled geoelectric conditions to support substation monitoring, line exposure reviews and operator briefings during changing storm conditions.
Three ways to put the data to work.
Prioritize substation monitoring
Review relative modeled risk for registered substations or individual locations. Compare the current assessment with the short-term outlook to identify assets that warrant closer observation. Keep the results beside your own measurements, equipment information and established operating thresholds.
Understand line exposure
Assess how line location, direction and ground conductivity influence modeled exposure. This gives planners a way to compare assets within a network and investigate why nearby lines can respond differently to the same regional geomagnetic disturbance.
Bring alerts into operations
Connect supported email or webhook alerts to the systems your team already monitors. Use alert levels and suggested action checklists to structure a review, then apply your approved procedures and operator judgment before making any operational change.
How it fits into your day.
During a storm watch, a control-room analyst reviews the substation assessments and flags the most exposed lines for discussion. As observations change, the team compares the modeled outlook with available station and asset measurements. Alert notifications support handovers between shifts, while the operator checklist provides a starting point for the briefing. Local procedures determine the response, including whether additional engineering review is needed.
Before you build.
Are the risk scores measured voltage drops?
No. Risk scores are relative modeled estimates, not calibrated voltage drops or equipment failure probabilities. Geoelectric outputs are estimates too. Assess them against operator measurements before assigning site-specific operational thresholds.
Can we assess a location before registering assets?
Yes. Point assessments let your team explore a location before registering substations for ongoing monitoring. Coverage and confidence depend on the available magnetic observations and conductivity inputs; review those details for each operating area.
