Geomagnetic storms can damage power grids.

the verdict
SUPPORTED
the evidence backs this
Recorded sources
10 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that geomagnetic storms can damage power grids?

Yes. Multiple sources, including peer-reviewed and official records, state that geomagnetically induced currents from storms can damage transformers and grid equipment, and the 1989 Hydro-Québec event is cited as a real disruption.
