This study evaluates the financial and environmental feasibility of electrifying a representative heavy-duty freight fleet over a 5-year horizon. The model integrates emissions accounting, discounted cash flow analysis, fuel price sensitivity, grid carbon intensity modeling, and route prioritization logic to determine when electrification is both operationally viable and financially rational.

All Routes Electrified
| Grid Case | EV Emissions (tCO₂/yr) | % Change vs Diesel |
|---|---|---|
| Diesel Baseline | 308.50 | — |
| High-Carbon Grid | 315.20 | +2.2% worse |
| U.S. Average Grid | 151.69 | −50.8% |
| E.U. Average Grid | 98.50 | −68.1% |
| Low-Carbon Grid | 39.40 | −87.2% |
This highlights that transport electrification and grid decarbonization must advance in parallel to maximize climate benefit.
Routes were evaluated using:
Phase 1 Candidates:
Routes R3 and R2
(highest emissions and financial benefit within operational range)
This phased strategy reduces risk while maximizing near-term impact.
This model uses synthesized route data for demonstration purposes and excludes dynamic payload variation, battery degradation modeling, and advanced tax structuring. It is intended as a strategic decision-support framework rather than a deployment-ready operational model.
