For Agencies · NEVI Spec Sheet
NEVI-format spec sheet for the Duncan hub.
Every federal NEVI requirement, sided alongside the Duncan hub's as-designed specifications. Use for corridor evaluation, NEVI Round 2 reviews, or public reporting.
NEVI Compliance
Meets every federal NEVI minimum — designed to exceed them.
The federal National Electric Vehicle Infrastructure (NEVI) program sets floor requirements for publicly funded sites. The Duncan hub is designed to exceed every one.
| Requirement | NEVI Minimum | Duncan Hub |
|---|---|---|
| Power per port | 150 kW minimum | Up to 325 kW (Tesla V4) · 360 kW (Espen) |
| Ports per site | 4 ports minimum | 16 ports (4× the NEVI minimum) |
| Uptime | 97% minimum | Designed to meet or exceed |
| Connector standard | CCS1 required | CCS1 + NACS on Espen; NACS on Tesla V4 |
| Pricing | Transparent, per-kWh | Compliant pricing structure, open network |
| Payment | Credit card + contactless | Compliant (Tesla + Espen standard) |
Charging Network
16 DCFC ports. Tesla V4 + Espen EVC/D360. Heavy-duty capable.
Two hardware platforms, one service. Tesla V4 Superchargers pair with Espen EVC/D360 hyper-fast dispensers to serve every connector standard and every EV class — light, medium, and Class 4–8 heavy-duty.
Tesla
V4 Supercharger
10 posts
Up to 325 kW per post
- 6 standard V4 Supercharger stalls
- 4 pull-through stalls for Class 4–8 trucks
- Fed by 3 Tesla V3/V3.5 Supercharger cabinets
- NACS connector
Espen
EVC/D360
6 dispensers
Up to 360 kW per dispenser
- Level 3 hyper-fast DCFC dispensers
- CCS1 + NACS connectors
- Fed by 2 Espen 360 kW power cabinets
- Open-network, interoperable with all EVs
Heavy-duty access: The four pull-through Tesla stalls make this the only hub in the region public-charging-capable for Class 4–8 trucks. Fleet operators can charge on the same corridor their drivers already use.
Utility & Grid
A 2.5 MW Duke Energy service, built to scale.
The hub is fed by a 2,500 kVA Duke Energy transformer stepping down to 480V 3-phase 4-wire service at a 3,000A switchboard. That 2.5 MW headroom is what makes it possible to run 10 Tesla V4 stalls and 6 Espen 360 kW dispensers concurrently — and leaves margin for future battery storage and canopy solar.
Civil and power drawings are IFC as of 3/9/2026 — sealed in South Carolina, under Tesla review, and ready for construction.
