What Happened in the UK Blackouts?
It actually sounds like this was really useful though, as a lot of the systems involved will be improved in the future.<p>I'm not sure if the grid is already doing this, but they should trigger failures randomly, including Low Frequency Demand Disconnection schemes from time to time to ensure that all downstream systems are also ready (like the hospital someone mentioned that had an issue with the backup generator, or the trains that stopped working when the frequency failed). A bit like caos monkeys in dev environments.
