Tesla has opened its first publicly accessible Megacharger station for customers of the Tesla Semi, marking a key milestone in the company’s effort to build a dedicated charging network for electric heavy-duty trucks across the United States.
The new Megacharger site, located in Ontario, is designed specifically for Semi fleet customers. Unlike Tesla’s existing truck charging stations, which primarily serve internal operations, this location is accessible to external fleets operating Tesla’s all-electric Class 8 truck.
First Customer-Facing Megacharger Goes Live
The Megacharger station is situated at 4265 E Guasti Road in Ontario, California. Tesla lists the current charging power at 750 kW, although the company’s Megacharger technology is designed to eventually deliver up to 1.2 megawatts per charger.
This Ontario site represents Tesla’s third Megacharger location in the United States. The other two stations are located near the company’s Gigafactory in Nevada and in Carson, California, close to the 405 and 110 freeways near the Port of Long Beach. However, those sites are reserved primarily for Tesla’s own logistics fleet and select partners.

The opening of the Ontario facility signals Tesla’s transition from internal testing to building a customer-ready charging ecosystem for electric freight transport.
Expanding the Tesla Semi Charging Network
Tesla is rapidly expanding the infrastructure required to support the Semi’s large battery and long-haul capabilities.
The company recently updated its charging map to include over 60 Megacharger locations across 15 US states, offering the most comprehensive overview yet of the network planned for the electric truck.
Including the three operational sites, the map now shows 65 megawatt-scale charging locations positioned along major freight corridors stretching from the West Coast to the East Coast.
Two states dominate the planned rollout:
– Texas: 19 planned sites
– California: 17 planned sites
Most locations are currently labeled “coming soon,” meaning Tesla has not yet confirmed exact opening dates.
Partnership with Pilot Travel Centers
Tesla is also accelerating the rollout through a partnership with Pilot Travel Centers, the largest truck stop operator in North America.
The collaboration will establish Megacharger hubs at selected Pilot locations in several states, including California, Georgia, Nevada, New Mexico and Texas.
Construction is scheduled to begin in the first half of 2026, with the first charging stations expected to open as early as summer 2026.
Each Pilot hub will feature four to eight Megacharger stalls, using Tesla’s latest V4 charging technology capable of delivering up to 1.2 MW per charger.
Initially, these stations will be exclusive to Tesla Semi trucks, but Tesla could eventually allow other electric truck brands to access the network—similar to how its passenger-car Supercharger network opened to other EV manufacturers.
Megawatt Charging Designed for Long-Haul Transport
Tesla’s Megacharger system uses a decentralized architecture consisting of satellite chargers connected to a central power unit known as the Powerunit.
When fully scaled to 1.2 megawatts, the system is expected to recharge most of the Tesla Semi’s 800 km (about 500 miles) range in roughly 30 minutes, enabling fast turnaround times for freight operators.
The technology is derived from Tesla’s V4 charging platform, which is also being integrated into the company’s next-generation passenger vehicle charging infrastructure.
Tesla Semi Nears Market Launch
The growing Megacharger network suggests that the long-delayed Tesla Semi is finally approaching large-scale production.
The electric truck will be built at a dedicated facility next to Gigafactory Nevada, where Tesla has already completed the building and begun installing production lines. The plant is expected to reach an annual capacity of up to 50,000 trucks.
First unveiled in 2017, the Tesla Semi was originally expected to launch in 2019. After several delays, Tesla now targets commercial availability in 2026.
