EV Site Assessments & Load Studies
Every EV charging project starts with a question the site itself has to answer: can the existing electrical service support the chargers, and if not, what will it take to get there? A site assessment and load study settle that before any equipment is ordered or any trench is opened — the difference between a project priced and scheduled on facts and one built on assumptions that unravel halfway through.
FTCI treats this as the foundation of the whole build rather than a formality. Because the same team that studies the site also installs it, as part of a turnkey EV charging installation, the findings carry straight into design and construction instead of getting lost in a handoff between separate firms.
Why the Assessment Comes First
Skipping it is where budgets and timelines break. The most expensive surprises on a charging project — a service that can’t carry the load, a panel with no room to spare, a utility upgrade nobody planned for — are the ones discovered after work has already begun. An assessment moves those discoveries to the front, where they’re line items instead of change orders.
It sets the scope everything else depends on. Charger selection, electrical design, permitting, and the construction schedule all follow from what the assessment finds. Getting it right upfront is what lets the rest of the project run without backtracking.
What the Load Study Measures
A load study is more than reading the amperage off a panel. It builds a complete picture of what the site draws today and what it can support tomorrow, so the charging load can be added with confidence rather than guesswork.
Existing Service And Capacity
The study starts with the service entrance, panel ratings, and available capacity — how much electrical headroom exists before the chargers are added, and how much the new load will consume. This is where it becomes clear whether the site has room to spare or needs additional capacity built in.
Real-World Demand
Nameplate ratings only tell part of the story. Reviewing actual usage — including interval data where it’s available — shows how much of the service is genuinely in use versus held in reserve, which often reveals more usable headroom than a rating alone would suggest.
Infrastructure And Site Constraints
Beyond the electrical picture, the assessment maps the physical realities: where equipment can be sited, how far conductors have to run, what trenching or coring the layout demands, and how accessibility requirements shape charger placement. These constraints drive both cost and design long before installation.
Turning Findings Into a Buildable Plan
An assessment is only useful if it translates into an accurate build, and that translation is where a study done by the same team that will do the work pays off. Findings don’t have to survive a handoff to an outside contractor who priced the job differently or read the capacity another way — the crew that measured the site is the crew that builds it.
When the study does flag a utility upgrade, that early warning is what keeps it from becoming a stall. FTCI carries the metering equipment and switchgear these upgrades depend on in stock, so a capacity gap identified in the assessment becomes a planned step rather than a months-long wait. The result is a project scoped to be completed on the first try, without the go-backs that come from discovering the site’s limits mid-build.
What a Complete Assessment Includes
A thorough assessment leaves a property owner with a clear, decision-ready picture of the project ahead. In practice, that means evaluating:
- Existing service size, panel capacity, and available headroom
- The additional load the proposed chargers will add
- Whether a service or utility upgrade is required
- Equipment siting, conduit paths, and civil scope
- Accessibility and code considerations affecting layout
With those pieces in hand, charger count, electrical design, and budget rest on measured reality rather than estimates. That’s what turns an assessment from paperwork into the document the rest of the project is built on.
