This is not eliminating use-based billing. It's adding an income based fee on top of rate decreases. You'll still pay for the electricity at some of the highest rates in the world.

I have solar, and it's mostly (90%) not being utilized and sent back (I overspecced when NEM 3.0 was about to hit).

Prior to this, it made sense to sell it back to PG&E. Now I'm looking for uses to only sell back what it makes sense to sell back. Obviously transitioning gas therms and replacing with electric is underway (for heating/cooking), as well as charging an EV but there will likely still be excess.

So mining bitcoin? But only if I can spin up & down the mining when solar ramps up/down.
