Yes, it's a lot. But it can run when energy is cheap, such as when there is excess solar and wind.

There are other factories already that power up the most energy hungry devices only when power is cheap.

Industrial furnaces and forges aren’t actually things you can fire up and shut down on a moment’s notice. This would completely change the chemistry and maybe lead to batch deviation and scrapping the whole batch. But, I’m not super familiar with this specific process. Nevertheless, it seems unlikely to me they could take advantage of off-hour energy costs. In fact, the chemistry companies around where I live mostly have their own power plants for these kinds of operations.
