I was there yesterday and they were, in fact, working. It's not showing up in the official map, so maybe it was a fluke, but I'm not trying to mislead anyone!
As for 150KW... I didn't have an empty battery so I couldn't check the full rate. The stands say 500VDC/350Amp = 175KW, which would match 150KW once you take. But I checked Emeryville and it says the same thing so apparently that's not reliable.
