You can timeshift your power consumption, but in many cases you can not timeshift industry power consumption, especially heavy industry power consumption. For example it takes few hours to start a big plastics injection plant, it takes few days to heat an aluminum smelter. High quality glass production needs few weeks of uninterrupted power supply. Iron blast furnaces run without interruption for years.

But for example, cement production can be turned on and off quite easily, and is turned on and off on demand by the grid electric operators to help with grid stabilization (cement producers are paid for this grid stabilization service).
