So ... if V2Grid was available I could charge at work and then use, say, 10kWH [from teh car's battery] in the evening to power the house, and still have enough SoC to get to work the following day (depending on commute length, of course).
If I had a PowerWall I could "dump" more power, once I got home, leaving just enough SoC to get back to work the following day.
I know this is a concern of Tesla vis-à-vis Superchargers, but seems to me it could be an additional Perk for anyone charging at work.
5-days-a-week x 48-weeks-a-year x say 15p per unit comes to about £ 36 p.a. for each kWH "dumped" at home each weekday - with electric cooking / AV / Lighting etc. in the evening perhaps 10kWH is reasonable?, with static storage and a short commute maybe 20-30kWH per day is also doable? so £1,000 p.a. at the top end.
Might not be worth the hassle though - although maybe smart metering will "reward" me for not using power at peak times, so some additional benefit (or, more likely in this day-and-age, no penalty for peak time usage)
