EVs are the energy storage devices, which is why they hold the potential to smooth grid demand. Offer the right incentives and implement the right infrastructure, and it could ease the challenge of delivering exactly the right amount of electricity demanded in fractions of a second.
I expect utilities to come up with mitigating strategies prior to major problems being realized.
The most ham-handed mitigation strategy is rolling blackouts. That's a strategy of last resort when other incentives and disincentives fail to shape demand sufficiently.
I've already said that demand shaping could be effective if consumers were given sufficient data in a way they can understand, and real time pricing were implemented.
