Tesla PR at its best! 100MW is neat. 20,000 DERs doing DR is good. But...
I don't see why this is considered a special milestone? What was new that we learned from this DR event? Turning OFF devices or telling a lot of DERs to DISCHARGE at same time is really simple and not really a virtual "power plant" and more like a "virtual power relay"
There is so much more to do here vis-a-vis VPPs: dynamic prices, grid-aware coordination of DERs (where is the grid?), engage C&I buildings, and carbon-aware load shaping. As more and more DERs land on the grid, these elements become important to get right. And simple, discrete DR events will not be sufficient to ensure reliable load-supply balancing.

Why this Tesla PR is not news (imo):
-- In 2022, Tesla managed 6,200 power walls and provided 25MW DR with same mechanism as today. 6,200 PowerWalls became 20,000 over 2 years. That's nice growth. How much did people earn for allowing Tesla to use their hardware this time? Does it lower barrier of entry to PowerWall-utopia?
-- Tesla's AutoBidder platform already manages 1000s of PowerWalls to do frequency regulation (which is much harder DER coordination problem).
-- Utilities and aggregators have managed the same type of (discrete) events for decades with 10,000 to 400,000 of water heaters and HVAC units (e.g., 10MW in VT and ~100MW in Florida/Duke Energy). Simple one-way comms and controls.
-- MosaicPower (and others) has been around 10-15 yrs and actively manage 14,000 water heaters to provide ~14MW of **continuous** 24/7 frequency regulation (Reg-D in PJM). Again, a harder DER coordination problem.
Last night, the Powerwall fleet in California delivered more than 100MW to the grid during a Virtual Power Plant event, reducing the need for fossil-fueled peaking plants.
VPP programs are available for customers of Pacific Gas and Electric Company, Southern California Edison (SCE), and San Diego Gas & Electric through the California Energy Commission
