Tesla has opened its first public Megacharger station in Ontario, California, designed to rapidly recharge its electric Semi trucks, the company announced over the weekend. The station, located at 4265 E Guasti Road, is now available to customers who have taken delivery of the Semi, though deliveries remain limited.
The Ontario location is strategically positioned in the Inland Empire, a major freight corridor near the intersection of the I-10 and I-15 freeways, facilitating transport between the Ports of Los Angeles and Long Beach and inland distribution centers. This placement is intended to support long-haul trucking operations by providing a critical charging point for electric vehicles moving goods throughout the region.
While Tesla has previously operated Megacharger sites at its Gigafactory in Sparks, Nevada, and a facility in Carson, California, near the Port of Long Beach, those locations primarily served Tesla’s own fleet operations. A private Megacharger is also in use at a PepsiCo facility, an early customer of the Semi. The Ontario station represents the first explicitly customer-facing Megacharger location.
The novel Megacharger is currently capable of delivering charging speeds up to 750 kW, though Tesla’s Megachargers are designed to reach up to 1.2 MW. At 750kW, the station can replenish up to 60% of the Semi’s range in approximately 30 minutes, a speed intended to align with mandatory driver rest breaks.
The opening of the Ontario Megacharger is part of a broader plan to deploy at least 64 additional public Megacharger locations across the United States. Tesla has released maps outlining planned sites, with a focus on Texas and California along key Interstate freight corridors. The company currently lists two other operational Megacharger sites, one at a Tesla Megapack facility in Lathrop, California, and the other at the Nevada Gigafactory.
The development of the Megacharger network comes as Tesla continues to ramp up production of the Semi at its Nevada factory. However, the Semi program has faced significant delays and a gradual rollout, with mass production and widespread deliveries yet to materialize.
