I definitely had no problems with electricity all of today (on the eastern side). And there was nothing in the news about local outages either.
Funny enough, there were news before the Easter holidays that they're preparing for extremely reduced demand by shutting down facilities.
In any case, if I recall correctly from a Youtube video I can't find (it was either Wendover or Real Engineering), if the grid is fully down, it takes quite a lot of effort and time to bring it back online because it has to be done in small steps to avoid over/under loading/using.
Very good video. Very good channel.
