-- as Spain clearly demonstrated on 28 April 2025, when wind and solar was supplying 71% of the produced power, and a 5-second interruption caused tripouts across the Iberian peninsula and southern France, resulting in a total power outage lasting ten hours or more.
While renewables were part of the cause, they were not the sole cause, a lot of things combine to result in the voltage swings and cascading outages; even the investigations pointed out that more spinning power alone would not have stopped the event.
