Most utilities in North America design their physical infrastructures to withstand

no more than once every 50 years. The risk of catastrophic damage or an outage
in any given grid system from GICs probably is much smaller than that. What is more,
damage incurred from a severe terrestrial storm would generally be more costly and
difficult to repair.
