@robhawkes Very nice! Do you have something which defines terms like 'turn up'? and similar for the battery storage?
Which APIs let you get the current state of each battery; one thing I've had as an idea for a while is to have a 'current charge' state for the country but also to look at how that changes over time as we add more batteries.
Hmm, aren't there some compressed air storage around as well?

@Thayer hmm, is that something you can fast track via going through data-protection stuff?
