My situation: have EV/PV, NEM 1.0, net generator
Unless I'm mistaken, I spoke with SDGE solar/EV specialist, who told me that any energy put back into the grid via Powerwall will be credited at retail pricing. At year end in March during "true up", any unused credits will be converted to wholesale pricing which is $0.02-0.03 per kwh. While TOU load shifting is allowed, all this does is generates energy credits.
Basically, what this means is that the credits I have currently for over-generating (about $1000+ retail) is worth $40 come year end. Many have the idea to draw battery at off peak and sell back at peak hours, sounds good in theory but the utilities rig this game.
For SDGE, this basically destroys any opportunity for arbitrage using Powerwall or to use it to substantively offset the cost of Powerwall installation.
Battery backup is not worth thousands to me.
