Tesla has opened its first Megacharger station for its Semi electric truck customers in Ontario, California, marking a significant milestone in the company's push to build a nationwide charging network for electric commercial vehicles. The new 1.2 MW charging station is located in the Inland Empire, one of the busiest freight corridors in the world, and is designed to quickly recharge Semi trucks during mandatory driver rest breaks.

Why it matters

The opening of this first public Megacharger station is an important step in making long-haul electric trucking a viable option for fleet operators. Tesla's high-powered Megachargers can replenish up to 60% of a Semi's range in just 30 minutes, addressing a key challenge for electrifying heavy-duty trucks. This new charging hub in a strategic freight location signals Tesla's commitment to building out the necessary infrastructure to support the adoption of its Semi model.

The details

The Megacharger station is located at 4265 E Guasti Road in Ontario, California, near the interchange of the I-10 and I-15 freeways. Tesla says this first public Megacharger is limited to 750 kW, though the company's Megachargers are capable of delivering up to 1.2 MW of charging power. Tesla already has two other Megacharger sites operational, but those have primarily served the company's own fleet operations. The Ontario location appears to be the first station explicitly opened for customer use.
