Portland General Electric (PGE) is positioning electric Class 8 semi trucks and medium-duty commercial vehicles as grid-ready assets capable of providing backup capacity during peak load events. At Oregon's first fleet-focused electric ride-and-drive, PGE transportation electrification manager Karla Hendrickson described battery-backed big rigs as 'batteries on wheels' that can help the utility manage high-demand periods while keeping costs low.
PGE is already testing vehicle-to-grid dispatch from electric school buses, citing their predictable schedules and long parked durations as ideal for distributed energy resource participation. The utility's approach treats parked commercial vehicles as flexible capacity rather than passive loads.
State DEQ officials noted that heavy trucks and buses represent a disproportionate share of transportation emissions despite being a small fraction of the fleet. This imbalance is a key driver behind state and utility interest in accelerating medium- and heavy-duty electrification.
| Metric | Detail |
|---|---|
| Registered EVs in Oregon | Nearly 150,000 |
| Utility | Portland General Electric (PGE) |
| V2G test platform | Electric school buses |
| Target segment | Class 8 semi trucks and medium-duty commercial vehicles |
This means fleet operators and procurement teams evaluating electric Class 8 trucks should assess V2G readiness, bidirectional charging capability, and battery cycle life as part of total cost of ownership calculations. Utilities may increasingly offer incentives or dispatch programs that turn parked commercial vehicles into revenue-generating assets. Buyers should confirm charger interoperability, telemetry integration with utility dispatch systems, and warranty terms covering V2G cycling before committing to large fleet orders.

Commercial vehicle V2G requires battery systems engineered for high cycle life and bidirectional power flow. Cell selection, thermal management, and BMS architecture must be validated against duty cycles far more demanding than passenger EV use cases.
