On September 9, a heat wave pushed California’s grid demand to new heights, and more than 140,000 home batteries discharged a record 580 megawatts over three hours, according to reports from Sunrun and Tesla.
The coordinated discharge, described as the biggest residential virtual-power-plant event, helped ease wholesale prices and provide extra supply. Tesla Powerwalls accounted for 517 megawatts, with Sunrun owning or running 55% of those units.
Meanwhile, the next evening, Southern California Edison requested another three-hour release, delivering over 140 megawatts. If both nights had overlapped, the companies estimated more than 720 megawatts.
Sunrun CEO Mary Powell said, “The home-battery network now rivals many traditional backup plants.” She added that it can lower costs for people who never bought a battery.
Tesla rose about 2.4% to near $373, while Sunrun gained about 4% to $8.87. However, retail sentiment on Stocktwits remained bearish for both stocks, with TSLA falling 17% and RUN losing 52% this year.
