Just a thought:- I wonder if an arrangement could be made with some industries (e.g. Aluminium producers) where they took a lot of cheap power when it was available and less, expensive power, when it wasn't. IOW a form of demand side management. It could be a way of mitigating the requirement for storage, making renewables more useful. Perhaps they already do this?
