Texas Superchargers Out of Service?

I am thinking the other way. If the power is out, can you use your electric vehicle battery to keep the lights on in your house. 70 Kwhr should be able to power your house for 4 days, maybe longer.

yea, would be nice for some limited use. There are threads about that on here. Yet, as you probably know, the Tesla doesn't have that capability built in.

Time-shifting of energy cost with battery storage sounds good on paper, but once you do the math it's unlikely going to save you any money. I've got 9c per kWh at night, and in summer over 40c between 4-9pm, and even that isn't enough to make it work. The initial cost of the powerwall or other battery storage is virtually impossible to recover (also for me it would be rather expensive as it would require updating of the main panel, and likely going from 100A to 200A service).

BTW: it could work when you do NOT have net metering, I think there are states that do not mandate that. Also not having gas service for hot water/cooking/heating would help.
