FAILL!!! All coal plants where on standby burning lots! LOTS! of coal!! Really! And also the gearing doesnt't matter fucks for modern mills because they have frequency(very expensive!) frequency converters. The mill you @Tom Scott are sitting on is really small. The ones here are huge and use HUGE DC magnet generators!,(reply>), Pumped storage is A joke.Here in the Netherlands quickstart power is provided by gas turbines and diesel engines.Germany has just approved  hundreds of MegaWatts of diesel buffer power! for their failing windmills! How green you want to get it?,(reply>), Like Germany has so much pumped storage. And what system capacity are you talking about!? The overloaded power grid or those of neighbouring countries? that share the same problem!?,(reply>), Utter rubbish, plant on standby is not burning any coal, they simply take longer to get back on load. Pumped storage and system capacity takes care of fluctuations.
