Tesla Powerwalls just powered the largest residential distributed power plant dispatch ever recorded
During extreme heat in California, more than 140,000 home batteries were dispatched for 3 hours, reaching 580+ MW of peak power back into the grid
Tesla Powerwalls absolutely dominated the event:
• ~110,000 Powerwalls participated
• 517 MW came from Powerwalls alone
• Another 63 MW came from 30,000+ other home batteries
• Tesla Powerwalls delivered nearly 90% of the total peak output
• 580+ MW total peak output
• Enough to power every household in Sacramento County during peak hours
The scale is insane
More than 100,000 Tesla Powerwalls sitting inside people’s homes effectively operated as one massive distributed power plant exactly when California needed it
And there was even more capacity available
Tesla and Sunrun reported that their fleets had the ability to deliver more than 720 MW if the following night’s Southern California dispatch had happened at the same time
This is what Tesla’s vision for distributed energy starts to look like at real scale
