Wow - $2.00 is crazy. I pay $0.15 per kWh (pacific northwest, inexpensive hydroelectric power). 13X, quite an incentive, even if rare.

California's PG&E is the biggest utility in the US. In their territory electricity on the default residential plan ranges from $0.41 to $0.54 per KWh.

Still, that's 4x back. It really helps incentivize buying a larger powerwall, and disincentivizes the power company from sapping the battery dry right before you need it.

Yeah, I'm not saying it's a bad deal for the battery owner, but rather that it isn't the huge spread that you had assumed based on a reasonable electricity price. :shrug:

How many hours a year would one expect to get this?

And they’re raising prices again next year.

You're paying retail rate. The utility pays spot prices and attempts to manage the spot price vs retail rate spread over a window of time.
