Basically, if you can control lots of water heaters, fridges, refrigerated wharehouses, A/Cs, etc.. You have a way to store power (f.ex. you make the water a couple degrees hotter, or the wharehouses a couple degrees lower). Not enough to affect what's in it, but enough to use that extra power and "store" it (which buys you time, and means that you can use less power later, ie. shut down a gas plant or whatever while all those things revert to normal temp).
