why can’t a power plant “dump” extra unused electricity?

Question

Some countries produce too much electricity at a certain period of the year, and have to pay another country to get rid of their extra own unconsumed electricity. Why can’t a power plant produce more electricity than consumed, what’s the physical obstacle to do so?

Also, what will the receiving country do if this surplus of electricity is again not consumed entirely?
