@yobigd20 Without reading the study, I am skeptical. It is easy to come up with such a small increase in load if you just consider the increase in energy over a 24 hour period, instead of the peak increase in power. If you take the worst case scenario (all cars electric and everyone plugs in between 8 and 9 am at work), then the numbers are quite different. I'm familiar with MISO, so let's take that as an example. (I used Wikipedia numbers unless otherwise stated.)
The states under MISO (excluding Illinois and Manitoba, just to be conservative) have a population of about 37 million. At 0.8 cars per capita, that's 30 million cars. At a low 3.3 kW, that is almost 100 GW of additional load. MISO just released their 2013 summer load forecast - peak load 93.8 GW (Summer Readiness Workshop Presentation.pdf). So we are talking about more than 100% of the summer peak load. Even if we could spread this out over 24 hours at about 13 kWh per car (40 miles) per day, it is still 16.7 GW. Not quite 2%.
