The pipeline combines solar-wind forecasts with local geography to estimate substation risk, detecting nearly 80% of major events and warning 30–60 minutes ahead. It offers a concrete example of translating forecast inputs into location-specific operational predictions.

What
A machine-learning pipeline forecasts location-specific space-weather risk for 66,935 substations in the continental United States.
How
It combines AE and Dst forecasts with location features, estimates dB/dt using gradient boosting, then produces risk estimates 30–60 minutes ahead.
Why it matters
Location-specific advance warnings can help grid operators respond to space-weather threats to power infrastructure.
