Excess power on the grid is a very real problem though. It's easy enough to shut off photovoltaic solar when not needed (which is probably what should be happening here!), but industrial scale generators cannot all be turned on or off on a whim. Serious damage can result if power production does not match the load.
It's easy to dump a few kW (just boil some water or turn on a heater), but dumping many MW or even GW is not trivial.
