Sunrun and Tesla Set New Records with 745 MW Grid Dispatch During…

Event summary

Sunrun and Tesla dispatched a record 745 MW of power from residential batteries to California’s grid on October 6, 2026, surpassing the previous record of 669 MW set on October 5, 2026.
The dispatches were triggered by the California Independent System Operator’s day-ahead locational marginal electricity price exceeding $200 per megawatt-hour.
Sunrun alone has over 120,000 residential batteries enrolled to support California’s grid.
A new Google-funded distributed power plant with PG&E, involving Sunrun, Tesla, and Everyday Electric, is set to begin initial dispatching in October 2026.

The big picture

Sunrun and Tesla’s record-setting grid dispatches highlight the growing role of residential battery storage in managing peak demand and stabilizing the grid. This trend is part of a broader shift towards distributed energy resources, which are increasingly being integrated into utility operations to enhance grid reliability and reduce costs. The involvement of major players like Google and PG&E underscores the strategic importance of this transition.
