Y2k problems will kill the satellites and sunspots will do the rest!

I fell sunspots will have no job to do, as Y2K will finish the satellites before that(!!)

Even without the sunspot problems, it would seem that if voltage were to drift outside the 5% - 10% parameters due to Y2K grid fluctuations, that the grid would go down no matter what.
High-performance transformers are delicate machines. They are designed to cope with voltages within a specific range of amplitudes and frequencies. Outside these bounds, the transformer behaves unpredictably. The trouble with GICs is that the voltages associated with them change this delicate balance. In particular, they set up voltages at harmonic frequencies to the ordinary load. These frequencies are transformed but in a way that can rapidly spiral out of control. The result is wildly fluctuating voltages called voltage asymmetries. If the power is not shut down, these can create enough heat to damage the iron core beyond repair. Worse, these fluctuations pass rapidly through the network so that neighbouring transformers also become affected. Within seconds an entire network can collapse as one transformer after another fails. Exactly this happened to Hydro-Quebec's power system that fateful morning. "Voltage regulations need to be within 5 to 10 per cent of a nominal value. If you fall outside that, you generally see a system collapse and the start of a domino effect," says John Kappenman, an expert in the effects of geomagnetic storms at the Metatech Corporation, based in Goleta, California.

I'd think the windings would be smoked long before any harm was done to the iron core.
In either case, the end result would be the same.
