Tesla deployed 13.7 GWh of energy storage in Q3, its second-highest quarterly deployment total.

Tesla’s third-quarter energy-storage deployments totaled 13.7 gigawatt-hours, its second-highest quarterly total according to the supplied earnings summary. This figure measures storage deployment in energy units, not electricity-generation capacity or data-center power demand.

The earnings reports put energy generation and storage revenue at $2.88 billion, compared with an analyst expectation of $3.91 billion. Tesla’s chief financial officer said the energy-business gross margin increased from 20.4% to 33.1%, primarily because of tariff refunds and warranty-expense adjustments.

Tesla also reported a record order rate for its storage business, while Elon Musk said 2027 Megapack availability was almost entirely sold out. Those statements describe company-reported demand and forward bookings, not additional deployments completed during the quarter.

A separate earnings summary listed 50 GWh as the planned capacity for MegaFactory Texas. The supplied text does not specify a time denominator for that manufacturing-capacity figure, so it should not be restated as annual capacity or combined with the quarterly deployment total.
