What would the consequences be?
In the modern world, we use electricity for so many things. We require electrical power to pump water into people's houses and to pump the sewage away. [You can imagine] what could happen if the sewage systems aren't pumping stuff away. If you don't have power, you can't pump fuel into vehicles. If you don't have any fuel, traffic could come to a standstill.
Could the economy function? Most of the time you're using credit cards, debit cards or you'll be getting money out of an ATM. If you've lost the power, the computers in the bank that keep track of our money will have back-up power, but not the ATMs or the machines in the shops. So if you had a big power outage, it wouldn't be long before we'd be trying to find cash.
What can be done? The biggest step is to make more and more people aware of the issue, so they're thinking about it in the way they design things. That's the most critical part. I think it's also getting a better picture of these very violent past events. We'd like to find out more about the scope of those events. We have a lot of old data from past events that's on paper — in newspapers and so on — and we're busy trying to find ways to turn it into digital.

I believe they're the most vulnerable because of the population density in those areas in conjunction with their reliance on the electrical grid.
The number of flares and sunspots fluctuate each year reaching a maximum every approximate eleven years. The Sun was due to reach a solar maximum in its 11 year cycle in 2011 or 2012. The current solar maximum was expected to be less severe than normal, however recent observations suggest that the maximum will now be delayed and occur in 2013 and be 40-50% stronger than the last maximum in 2001.
Carrington Event 1 in 8 chance of occuring in the next decade
Could such an event happen today and what would be its impact? It is likely that the electrical activity in polar regions could drive large currents in the electrical grids causing large-scale and possibly long-term damage.NASA appears to be sufficiently concerned that it is launching the “Solar Dynamics Observatory” which will study the sun in unprecedented detail. This should improve our understanding and ability to react to any threat.
It is not possible to predict with certainty when the next Carrington event will occur but a recent report based on modelling of the sun has determined a 12% probability that such an event will happen in the next decade. commend the foresight of those that warn us of the potential for harm from our normally friendly neighbor.

Except that 8 hours of back up power, and no huge earthquake / tsunami to cause said destruction to those nuclear power plants, gives those engineers enough time to scram the reactor (fully insert the control rods). Once that's done (which takes seconds to minutes), the pumps only have to run long enough to continue cooling the reactor down. Since with the rods inserted all the way, the reactor is subcritical, no more heat is being produced, and the cooling water will stay below 200 degrees F without any pressure (being pumped).
so yah, loss of power grid? Sure.
Nuclear disaster because of a Carrignton event? I'm afraid that's fear mongering there......

Except the pumps won't work because they just got EMPed. Oh and that giant magnetic power turbine might just explode from the influx of solar radiation like the telegraph lines back in the day. How will the workers insert the rods with no working computer? How will they insert the rods with out working machines? Remember everything gets EMPed not just the grid.
does US really think it could could keep ALL of its 104+ nuclear power plants under control in a global disaster level event? again look at how much risk and damage and irradiation from the planet Fukushima has been causing for over a year now. but apparently so, since US is so confident that even since Fukushima and its own reactor leaks in the northeast, it's installing even more nuke reactors!
