No, if they are trying to run too fast, the current output will
increase, and the paower plant's breakers will disconnect it from the
grid. If it slows down, it will draw current, and become a motor. The
only "meltdown" is the customer's. If too many generators go off line
there is a massive brown out, or blackout.
