But as I also said, if this is cost effective, it sure would seem like the utilities would jump on it themselves. One large installation versus hundreds of homes makes a lot more sense. And those installations can still be small enough to be distributed around a populated area, to reduce distribution losses.

When solar/wind become big sources on the grid (w/o storage), it is a problem for the utilities - they may have to ramp up their peaker plants as these supplies vary, and they don't have any control over it. So at some point they will (and are) fighting that. But if people are connecting batteries, that helps to smooth out the variance - it's all good (if it is affordable).

Large scale , it has been done in Japan, even before the Fukashima disaster, using Sodium sulfur battery tech. I don't know id li-on is scaleable on an economic basis. The sodium sulfur tech has low losses in charge/discharge (under 10 %) but I wouldn't want it near my house.

Right, some utilities are looking into this, a few pilot programs are out there. But I do think they use batteries that are much cheaper than Lithium (the sodium sulfur you mention, some kind of iron something or other, probably a few others). Lithium is the choice for portable power because it has the best energy density, but size/weight isn't that important for a stationary application like a utility would be using. Same with safety, not nearly as important when you don't carry it in your pocket, or drive it around a public road.
