This incentivizes storage and time-shifting usage to solar peak times, which seem to be needed in California. Does anyone know if there are pricing signals to help with that? For example, if I (as a power-plant operator or whatever) found a way to sell electricity right as the sun is going down, am I rewarded for that?
As an individual with a solar install, I think this also encourages people to use the energy they produce directly, which also seems beneficial. For example, if your house is well-insulated, you can probably pre-cool it a few degrees while your solar is producing so that you don't need as much cooling during the peak times. If you can be home during the day time, you could set your car to only charge during peak times.

NEM3.0 incentivizes exactly that. It prices exported electricity at the avoided cost rate. During the late summer and early fall, between 7-9PM that can be more than $1/kWh, or 3x the average NEM2.0 rate [1]. Of course to maximize that rate you need to store energy and sell it back at the optimal time.
The average rate with NEM3.0, however, is much lower.
