Megawatt truck charging requires grid redesign

Tesla’s Semi video showing a peak ~1.2 MW charging session demonstrates that long‑haul electric trucking will need utility‑scale power delivery at highway charging nodes, liquid‑cooled cables, and new standards for sustained high‑power charging. Building that corridor infrastructure involves permitting, local distribution upgrades, new interconnect rules, and likely coordination with transmission and generation planners. — If commercial trucks routinely draw megawatts to fast‑charge, policymakers must plan grid upgrades, charging‑corridor siting, standardized connectors and financing models now — otherwise electrification could stall or shift costs back to fossil generation and utilities.
