This is why everyone should support Solar Rights Alliance, go to there web site and join they have helped in keeping monopolies like Pacific Graft and Extortion from screwing solar customers.

Under NEM 2.0 we saw peak rates starting in the afternoon when the sunlight would be available. Under NEM 3.0, it's completely within the Utility's right to decrease the NEM rate during the afternoon and dramatically increase the NEM rate at dusk. This lowers the value of the energy generated by solar, and increases the cost of energy used during peak times after sunset

There's a difference between Net Metering and Time of Use. What you're saying (charging less during the day and more at night) will happen to all solar customers regardless of NEM 1.0, 2.0, or 3.0.
Socal Edison has already shifted what hours relate to "peak" periods to later in the afternoon and changed prices during the day for NEM 1.0 and NEM 2.0 customers.
From my understanding, NEM is to guarantee 20 years on the compensation structure, but has nothing to do with peak/off peak periods or specific pricing of what they can charge during those periods.
NEM 1.0 = Retail pricing for generation Credits.
NEM 2.0 = Retail price minus "non-bypassable charges" for generation credits.
NEM 3.0 = from my understanding, paves way to move away from "retail" or includes new variable tariffs to further reduce generation credits.
At least for Socal Edison, the only grandfathering we get is to stay on our originally selected TOU for at 5 years from PTO. After that, they can and will start to shift customers from the old TOU-D-A, TOU-D-B, EV1, etc to the newer and less solar favoarble TOU 4-9, 5-8 or PRIME schedules.
Rate arbitrage is using the PWs to shift the rate schedules. You charge PW at off peak or should and power house frmo PW during peak. You are netting the difference in rates as a benefit.
You cannot send electricity from PW to grid, but by Powering house from PW during peak, you are maximizing the solar credit back to the grid
We are essentially doing cost avoidance. But, this different than in other countries. As I understand it, they can suck up solar energy and put it in their Powerwalls. And then sell those kWh in their PowerWall back into the grid at peak times and get the paid/credited based on the current high rate.
The CPUC has already allowed a shift in the highest rate window to devalue solar production of commercial customers. Our commercial TOU highest tariff now starts at 4pm, instead of noon. The hours of the highest solar production are bumped to the cheapest TOU tier.
And you did not read a word about in our State Government announcements or the media. It is move by the utility to essentially seize a portion of their customer's solar production.
I think the new plan is called the New Green Steal?

I am still grandfathered in for TOU-D-A until next year I think. I thought I could kept TOU-D-A for 20 years... but that's not the case. So in a year or 2, my NEW 2.0 solar production will be selling at the lowest rate anyway... how would that be different than NEM 3.0?
NEM 3.0 will have many more “non bypass-able charges” or NBC’s than NEM 2.0. So folks will see higher recurring tariffs and probably more up front cost during PTO.
I believe residential NEM 2.0 would still keep more favorable TOU rates than 3.0 though. There are many existing NEM 2.0 customers who are in solar leases and were generally sold solar assuming a certain level of savings versus what they experienced before.
I hope the TOU tiers don’t get overhauled on NEM 1.0 or NEM 2.0 customers where peak daylight time is significantly decreases. Homeowners will get pinched with higher than expected true up bills since their production in daytime won’t match the value of their usage after dusk. This mandatory TOU gamesmanship is where the utility can stick it to the PV-only homeowners.
Of course PG&E will probably just blame the unsuspecting homeowner for having light bulbs, cooking dinner, or watching prime time TV.
Have not closely read all the posts, but my interconnection agreement with PG&E back in 2018, and the associated tariffs PG&E published, did not prohibit grid export of energy from Powerwall that was generated from solar. The only restriction was basically "your total grid export for the year must not exceed what our billing system models your solar system could produce during the year." What is lacking is Powerwall support to do easily do generation time shifting.
A CPUC decision a year or two ago established that with Energy Storage, you can choose to either (a) charge it only from on site generation--then export to the grid is unregulated or (b) charge it possibly from the grid--then instantaneous export to the grid must not exceed instantaneous generation.

This has already happened. I am on NEM 1.0 due to my solar installed in 2012. I was enrolled in E-9A then elected to jump to EV-A, then was kicked out into EV2-A. The move to EV2-A drastically devalued my solar production before 3pm. For people without Powerwalls, this is a huge hit. In my case, the impact is not that significant because I can absorb almost all my solar in the batteries and use that energy later during the more expensive TOU periods. However, this is only true because I have a pretty small solar system. Any solar that I add (above 1.0kW CEC AC) would kick me out of NEM 1.0 and would likely only be worth Off-Peak price. That makes it much harder to justify expanding my solar array.I hope the TOU tiers don’t get overhauled on NEM 1.0 or NEM 2.0 customers where peak daylight time is significantly decreases.

They just need to buy more Tesla PowerPack to store all the solar power for a few hours and then feed it back into the grid during the peak.I haven't seen the requirement for new construction to have solar mentioned in this thread. That will drive a glut of solar power during the day. I wonder if they are going to start throttling solar production during the day if they have excess capacity and no way to store it.
