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

392 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?

Storage capacity is the problem, you’d need incredibly large batteries to store the extra power and we just don’t have the technology yet.

There are potential alternatives, like you could use extra power to pump water up hill, then when it flows back down you can use it to run a turbine, but it’s an engineering challenge that might not make sense when you already have a water source you can use for hydroelectric.
