Then run parts at 105-110% and it gets really hard.
The power industry designs a grid that runs so close to capacity that if^W when something big fails, the whole grid shuts down in a cascade. They know it:
Rubbish again.
Welcome to the wonderful world of physics. Ask your favourite physics professor what does
E1 = E2
in context of yesterdays events.
That's not really answering the question, and it's also not entirely right.

But you *can't* just simplify this to Ein = Eout.
No, it is spinning physics that does not work - physics *is* simple as long as one does not skip the linkage between different things: Econsumed = Econsumed_productive + Qreleased + Wreqired Econsumed_productive is what you actually used Qreleased is the energy released in a form of a increase/decrease heat Wrequired is the work required to get Econsumed.
