By 2050, 50% of the U.S. vehicle fleet will be electrified —more than 150 million cars and light trucks in all. With an average battery pack size of 18.4 kWh, this would amount to nearly 2,900 GWh of energy storage capacity. The addition of such a large and potentially unpredictable load could present problems for grid management if electric vehicle charging is not handled effectively.
http://www.rmi.org/RFGraph-electric_system_disturbances
There is some uncertainty in the reliability of the U.S. electricity system in a “business-as-usual” case. Although the U.S. electricity grid has a proven track record with conventional generation mixes, outages and grid disturbances are on the rise.

The dynamic nature of variable renewable resources presents challenges to conventional electricity system operations. Production from wind and solar resources, in particular, is both variable (fluctuating throughout the day according to availability of the “fuel”) and uncertain (weather forecasting is required and by definition is not always accurate).
