TeraWatt Infrastructure

TeraWatt Infrastructure (operating as Terawatt Infrastructure) is the nation's leading purpose-built EV charging infrastructure platform for commercial fleets, headquartered in San Francisco, CA (with roots in Santa Clara, CA). Founded in 2018 by Neha Palmer, Ethan Goldsmith, Benjamin Birnbaum, and John Rapaport, Terawatt designs, develops, owns, and operates high-powered electric vehicle charging depots and stations purpose-built for two primary segments: autonomous and rideshare fleets (with private or shared sites customized for security, data, and operations), and trucking fleets (light, medium, and heavy-duty), featuring pull-through stalls, high-powered chargers, and reservable bays. Their model is end-to-end - they acquire and develop land in strategically relevant locations, negotiate utility relationships for maximum power delivery, stress-test all hardware at an in-house lab, and provide customers with real-time dashboards and charge management software for full operational visibility. With over $1 billion raised, Terawatt claims the largest portfolio of purpose-built fleet charging sites in the U.S.

Terawatt's differentiation lies in its infrastructure-as-a-service approach: rather than asking fleet operators to manage the complexities of site selection, permitting, utility coordination, and charger uptime, Terawatt handles all of it "behind the scenes." Their hardware lab stress-tests every charger before deployment to ensure maximum uptime, a critical reliability standard for commercial operators who can't afford downtime. The company serves customers ranging from autonomous vehicle operators to major rideshare companies, regional trucking carriers, and enterprises such as PepsiCo. They also partnered with the New Mexico DoT on a $63.8M federal EV charging grant, and launched the I-10 EV Charging Coalition - the first U.S. over-the-road electrified long-haul trucking corridor - with partners including C.H. Robinson, DHL, Electrolux, and IKEA.

Terawatt is strategically significant to the U.S. energy supply chain because commercial fleets represent a highly concentrated, accelerating source of electricity demand. Purpose-built depot charging for medium- and heavy-duty trucks, delivery vans, and autonomous vehicles requires massive power infrastructure that cannot be served by consumer-grade chargers. Terawatt's model - combining real estate, utility partnerships, hardware, software, and financing - creates the backbone for the electrification of U.S. freight and mobility networks. Their recognition on TIME Magazine's World's and America's Top GreenTech Companies 2025 lists underscores their growing role in decarbonizing commercial transportation, a sector responsible for a significant share of U.S. greenhouse gas emissions.
