Reply to comment by DrMooseknuckleX in eli5: how long would power stay on if the power company abandoned their post? by larsattacks94

It's honestly still too optimistic. Even making it one hour seems unlikely with no human input.

Yes, but it includes the human element that is needed. All the others arw like "a gas/wind/nuclear" plant can produce X power for X time, without the human element of diverting and channeling the electricity. Sure the plant can keep producing, but that doesn't mean anything if it just overloads the grid.

It includes that element, but still underestimates it. People here don't seem to realize just how little this process it automated.

I can see where modern plants would have some type of "dead-man switch" or "heartbeat" safety system where it would shut itself down if there were no human responses to periodic prompts.

There's no "dead man's switch". The issue is simply the ephemeral nature of electricity. For the grid to work everything has to remain in perfect balance. It really doesn't take long for it to drift of course without a guiding hand.

As all things should be.

/you may now discuss the effects of only 50 percent, instead of all, of the operators and technicians disappearing without warning

Well, in theory, that balance could be achieved through software/automation. But it would not be considered reliable enough to run without some level of human oversight. Kind of like Tesla's self-driving mode.

In theory yes it could.

However in reality it means phone calls from the grid managers to individual power plant control rooms.

Yep. Happens every morning. Then they call me that night and ask for it right back. We wouldn't even make a shift change before the grid shit

In America, we would have people charging lightbulbs and tossing them into boxes haphazardly. Cause that's how power work.
