A new fleet charging depot has landed near San Francisco International Airport, and it's built specifically to keep one company's commercial electric vehicles running around the clock. The 6.6-megawatt site in South San Francisco is one of four purpose-built depots in a national rollout by charging infrastructure company Terawatt Infrastructure. The company says the South San Francisco buildout is complete and Nashville's site supports local fleet operations, while Miami's site is opening this quarter and Dallas's is set to go live this quarter. Terawatt says its network can now charge more than 3,000 vehicles a day.
Four Cities, One Coordinated Buildout
According to a PR Newswire release, the new depots in South San Francisco, Nashville, Miami, and Dallas together deliver 22 megawatts of dedicated charging capacity. Terawatt says it oversaw every stage of development on the sites, including entitlements, utility interconnection, and site design, and will continue managing day-to-day charger operations and maintenance going forward.
The South San Francisco site sits near SFO and is built to support one fleet's Bay Area operations, per the same release. Terawatt says it finished the buildout ahead of schedule and trimmed costs by six figures through its site-energization approach and work with Pacific Gas & Electric Company.
Nashville and Dallas Round Out the Rollout
In Nashville, a 4.5 MW depot near Nashville International Airport is positioned to support local fleet operations, the announcement states. The biggest of the four is in Dallas: a 7 MW depot near Dallas/Fort Worth International Airport that was scheduled to go live this quarter in support of another unnamed commercial fleet operator.
Terawatt describes itself as serving fleet operators including Waymo and Flexdrive by Lyft, though the announcement does not specify which operators are tied to each new site. The company says it now has nearly 30 charging depots in active construction or development spread across 16 U.S. markets.
How It Fits a Broader Pattern
This isn't Terawatt's first depot built for commercial fleets. The company's Rancho Dominguez, California, hub, located 12 miles north of the ports of Long Beach and Los Angeles, was reported fully operational by April 2025 with 20 pull-through and bobtail DC fast-charging stalls and 7 MW of capacity, enough to charge up to 125 trucks a day, according to a Terawatt Infrastructure blog post. That site was described as a private facility shared among multiple fleets, and the company said it had also launched small-footprint sites and full-build light-duty fleet sites in Inglewood and San Francisco over the prior 18 months.
Terawatt has also been looking to expand its Florida footprint beyond the new Miami depot. The company wanted to build its first Florida station on vacant land near Orlando International Airport, the Orlando Business Journal reported last November, describing Terawatt as a California company specializing in charging electric vehicle fleets.
Context From Waymo's Own Miami and San Francisco Operations
Miami's fleet-charging landscape is also shaped by Waymo, which already operates a depot in the same Wynwood/Design District area, situated next to a Florida Power & Light substation, according to Road to Autonomy. That outlet estimated roughly 30 to 35 chargers and more than 20 vehicles currently operating at the site, and reported observing Florida Power & Light crews micro-trenching there, which it interpreted as a sign of added electrical capacity for fleet expansion.
In San Francisco, Waymo's Bayview depot offers a sense of scale for what these facilities can eventually look like. The facility can service hundreds of robotaxis and has been operational for about five to six years, Business Insider reported, at a time when Waymo had deployed nearly 1,000 robotaxis across the Bay Area. Third-party workers there handle a range of tasks, from plugging in chargers to cleaning vehicle interiors and performing maintenance like replacing brakes, fluids, and sensors, according to the same Business Insider report.
Terawatt's own figures, as stated in its announcement, put its network's cumulative output at more than 93 million miles of clean driving range delivered for commercial EV and autonomous-vehicle fleets and more than 30 million kWh of clean electricity dispensed.
