Tesla's virtual power plant in California had its first emergency response event helping the grid by pooling power from Powerwall owners around the state. The event appears to have been a success as the distributed power plant looks like the future

>>$2 per kWh
That's good money. I would definitely opt in if I had a Powerwall.
>>16 MW of power at one point
That's pretty impressive. The Diablo Canyon nuclear plant is "only" about 140X that running at "nameplate capacity." There were about 2500 homes in the pilot program. So looking to the future, 350,000 homes would give you a surge capacity equivalent to Diablo Canyon. That's less than 5% of California single-family homes.
That's really encouraging. If they offered it to non-Tesla battery owners, I would at least consider upgrading my inverter or adding whatever software/firmware you needed to work with the standby system.
