A big power plant goes down and other plants have to pick up the load. Load exceeds capacity of remaining plants and they shut down (or breakers blow, etc). Repeat.
Power plants also need energy to start up (black start), and if there’s no grid energy to power those ancillary systems, or if the power plant doesn’t have on-site auxiliary generators to provide black start capability, they’re down until they can get power again from elsewhere.
Base load plants (coal, nuclear) don’t throttle up and down quickly for changing loads. For quick response, we use peaker plants which are typically natural gas powered turbines and can respond quicker (grid batteries are, thankfully, replacing these in some cases).
That’s grossly over-simplified but it’s more or less the gist of it.

This is huge, we have massive drills to make sure we can do this, and idle black start plants for just this purpose alongside almost an entire secondary grid for bootstrapping.
It trips me out that many of these plants don’t have APUs for starting themselves up, or that they were designed in such a way that they require utility power to boot up. Like I understand that black starts could have problems with frequency sync with no point of reference, but I can’t imagine that their control system circuits don’t have any form of self-powering redundancy built in to their design. Is there any reason for this?
Article doesn’t say, but one plausible scenario:

so it’s exactly like coal generators in Satisfactory

Electricity is expensive and hard as hell.
