Interesting thing showed up in my inbox. It looks like Sunrun is taking steps to allow PG&E to command my ESS to grid-export at peak time. The incentive to do this is to effectively "load shift" banked off-peak solar production and export it at peak time to generate peak NEM credits. Plus they'll give me $100.
I pinged my Sunrun rep and she thinks this may be why PG&E ran me through the PTO ringer. I guess my install was flagged as one eligible for grid export so they wanted to make sure my interconnection agreement was NEM2-MT in order to safely do this grid export since my insurance is covering damages to their grid if they initiate an export of my energy back to them... and things don't go as expected.
I've checked online and I can't find much information about this program other than some news articles that popped up last year during the brownouts. I'm wondering what command(s) PG&E can issue remotely to initiate this.
Edit: another link about this for SCE:
Anyway, no way in hell I'm signing up for this. I cannot control the maximum kWh they export on my behalf during one of the events. And I have no opt-in for this on the day(s) they pick. So there's a chance they run this program on hot overcast day, and I end up exporting what little power I have stored at 4 to 6pm. Then I proceed to take back peak energy from 7 to 9pm and just bear the cross of round-trip inefficiency.
Interestingly enough PG&E, CAISO, etc have wanted the residential homeowners who do this "help" to do so for free. Because doing it for a charge violates the monopoly rights of our favorite utilities.

“We delivered about 50 megawatts of relief to the grid on Friday evening — but we could have deployed about 50 megawatts more if all the policies were in place,” said Ted Ko, Stem’s vice president of policy and regulatory affairs. “What’s ironic is that the [CPUC] and CAISO have been putting up all these barriers to us participating, and then they called us and said, ‘Hey, can you do this for us for free?’”
