Can power grids be affected by solar storms?

    Absolutely, if powerful enough.  Solar storms generate ground currents that can, according to NASA, “melt the copper windings of transformers at the heart of many power distribution systems.”  In 1989 Quebec lost power fo 9 hours because of a solar storm.  Because power grids are so interconnected (some states receive power from other states) and currents and therefore damage can travel via telephone wires to other grids, a solar storm large enough could easily cause weeks of power outages.  And it wouldn’t just be electricity we’d be out of, but sewage systems, refrigerated medical supplies, water distribution, heating and air conditioning, and fuel re-supply.  It could be quite a mess.  A more sensationalized version of the effects are in the second link below.
