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

394 views

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?

Power plants have to match production to demand. If demand exceeds production, people lose power. If prduction exceeds demand, equipment breaks. There’s no grid-scale power storage option that surplus can be dumped into, so unless production can be decreased that surplus has to go somewhere, and it’s sometimes practical to “buy” another power grid’s demand. If that demand isn’t enough to soak up the excess it’ll just go onto other grids.
