Simulation 04 — EV Site Feasibility

Can your site
carry the chargers?

The first question on any EV charging project is whether the existing electrical service carries the planned chargers. This tool compares charger demand against available service capacity and indicates when a utility service upgrade becomes likely.

◆ Screening math: 3-phase capacity × 80% breaker rule, ~35% reserved for building load, ALM diversity credit on 10+ ports. Real feasibility needs panel schedules, utility records and a design site visit — that's the study we run in week one.

In short

  • EV charger demand is compared against available electrical service capacity to determine feasibility.
  • Three-phase capacity is calculated at a 0.8 power factor in this screening model.
  • When planned demand exceeds available capacity, a utility service upgrade is required and adds schedule.
  • Aria engineers Level 2 and Level 3 charging for fleet, public and multi-family sites, including surface lots and structured garages.
