Generating too much for the grid isn't an actual problem. Modern renewables can shut themselves off quickly. Most serious national plans involve overprovisioning.

You've never seen anyone credible worry about how we'll cope with that terrible excess of cheap power because it's not a problem, merely an opportunity.

You've probably mostly been reading complaints of the operators of non-renewable plants that can't do this and are annoyed they're being asked to do it when renewables are plentiful as it costs then money to do so, even on top of the lost electricity.
