Yes, it is how it works. You have rolling blackouts because the production is coming in too low to allow for repair downtimes on these plants. And that's caused by lack of redundancy and overall output brought about by shifting a quarter of the grid from working fossil fuel sources to boondoggle "green" garbage. The bottom line is that if these mills were instead fossil fuel plants (or much better, nuclear), then it's much more likely that the issues that the plants do experience could be managed with less loss of service.
