I forsee periods of negative/cheap/free electricity becoming much more common. If your equipment is not used on average two days a week, the economics start to look a LOT more sensible even for more capital intensive, energy intensive applications.

At the moment pretty much every MWh generated is a substituted MWh not generated by gas and periods of negative pricing are still relatively rare.

Wind is so cheap though, that at some point, overproduction will become the norm rather than exceptional and being able to timeshift your usage could, unexpectedly, end up saving you more money than reducing your usage.

The counterintuitiveness of this and the fact that this is new territory is why I think that there's lots of profit potential.
