If the grid were smarter it could schedule demand for the excessive production times. It could be used, for example, in render farms or other non-time-critical high load batch operations.
(Same thing also happens with iron / steel. I would assume electricity is the same, but I don’t have much knowledge. )
This is also why the turbine based systems that coal and hydro systems are so important to the stability of the grid. The physical momentum of the spinning metal stores considerable energy and can smooth over short lived inbalences in power consumption.
