I don't really know what to make of that article from cleantechnica. It says that renewables weren't the issue. But the head of the CA grid also said that "If the wind hadn’t run out, we would have been OK"[1]. Maybe this is wrong, but the way I interpret that is "When a fossil fuel plant conked out, it was the straw that broke the camel's back. But the reason that a single power plant failure led to blackouts is a heavy dependence on renewables without adequate storage or backups".

Real grids are much more complicated than you'd think.
Regarding costs of various plants, usually you calculate it as an average per kWh, which is still not quite right as dispatchable is worth more than non-dispatchable. (And yes, you can have renewable dispatchable.) If you compare those figures across technologies and locations, tread carefully, it is really easy to come to the wrong conclusions. For instance, you might be comparing theoretically estimated numbers with (somewhat old) real-world averages.
