As a part of grid balancing, we are already doing that to some extent. For the most part, the idea is that you can increase or decrease the load if you see the frequency of the grid beginning to drift off target. These types of frequency containment reserves can usually react very quickly, which means that most industrial processes don’t qualify.
However, since the duck curve is fairly predictable, we could (and should) extend this idea to slower processes too, such as the ones you mentioned. I don’t know if that sort of power reserve is actually being implemented, but it certainly would make a lot of sense.
It’s just that most industries prefer to operate 24/7. Having your reverse osmosis, electorlysis, electrowinning, arc furnace etc. running only during sunny hours is nice for the employees but bad for business. The investors of such factories prefer to see profits sooner rather than later, and restricting operating hours isn’t helping.
Cheaper electricity would obviously result in lower operating expenses, so I can definitely see some potential in this idea. You would just need to find some environmentally minded investors. They would also need to tolerate the risk that comes with a fluctuating power supply, which could be a tall order.
If the fluctuations of the local energy market are dominated by solar power, that means more work during the day and none during the night. If there’s lots of wind in the mix too, that could mean lots of night shifts during windy seasons and none during others, which isn’t great for the employees.
