Tesla marks the start of high-volume Semi production at its Sparks, Nevada, plant in late September 2026. The plant’s stated capacity is up to 50,000 trucks a year, while a September 29 snapshot lists five open Megacharger sites among 14 tracked U.S. locations. Factory capacity, charging-site status, and truck deliveries are separate measures.

Tesla’s Sparks plant has a stated capacity of up to 50,000 trucks a year

Tesla director of Semi sales Dan Priestly said the plant would soon be capable of producing 1,000 trucks per week. The annual figure describes the factory’s design capacity; the weekly figure describes a stated near-term capability. Neither is a delivery count.

A September 29 snapshot lists five open Megacharger sites

Loren McDonald, Chargeonomics’ CEO and chief analyst, counted five open sites among 14 U.S. Megawatt Charging System (MCS) locations listed as open, in development, or in pre-construction in a September 29, 2026, snapshot. Two of the five open sites were at Tesla locations. Three partner-operated sites were in Bakersfield, Fresno, and San Bernardino, California.

Tesla had proposed about 60 MCS sites and hoped to have about 30 operating by year-end 2026. Those figures describe a proposed network and a target, respectively.

Delivery forecasts differ from factory capacity

For 2026 deliveries, electric-trucking researcher Jason Roycht estimated that Tesla might deliver 250 or fewer Semis, citing his assessment of charging readiness. Earlier, Tigress Financial Partners had forecast at least 5,000 deliveries that year. Both figures are forecasts for 2026 deliveries.
