I was thinking the same thing. The gigafactory isn't mention in this, but could there be synergies with Tesla's (somewhat shady... pun intended) acquisition of SolarCity?
These sorts of installs aren't exactly the same thing, but maybe SolarCity needs to pivot to from distributed consumer to large scale utility.
Tesla has already deployed utility-scale storage in Australia and has contracts to build more for California utilities. Those are just the ones I know of.
