I believe it would be theoretically as if your house clothes dryer circuit breaker tripped but the dryer was wired to pull the same current from other breakers in the panel which exceeded their ampere ratings and therefore they all tripped.
Of course, a house electrical panel isolates the loads of various devices and trips only a single breaker. In the national power grid system, load is only isolated between the three massive power grids. This allows convenient maintenance shut-down of individual power generators without affecting the ability to shift load to various sources but is also its great vulnerability and weakness.
The solution, though costly, would be to isolate more generating sources from each other so a single failure would not place an excessive load on the system.
Another lesson to the country is states which use more power than they generate create an inherent weakness.
Liberals have fiercely fought new power plant construction but always want more juice for their electrically-powered toys and conveniences. The people got what they deserve for demanding the moon and refusing to create a system to meet their own selfish demands.
It’s too bad that the problem could not be isolated to only those selfish environmentalists. Maybe now, they will lose their stranglehold on the state legislatures, allowing new power plants to be built.
