Unfortunately, you can't simply hand-feed 100 coal into all the Spanish thermal plants and then plop down two more to be on the safe side until you've fixed supply...
it's that in Factorio there are no problems with phase synchronization, and the devices, consumers, producers, so the machines don't get damaged from a lot of abrupt starting/stopping.
still, it's strange that operators and grid controllers have to do the restart manually.
