Commercial EV Charging Station Installation in Denver
Charging stations for parking lots, garages, and fleet yards, designed around the service the building already has.
The first question on a charging project is what the building can already carry. A load study on the existing service shows the spare capacity, and charging equipment is treated as a continuous load, so each circuit gets sized above the charger's rating rather than right at it. When the chargers add up to more than the service has left, load management equipment can cap total draw so the site is designed around maximum simultaneous demand instead of the sum of every nameplate, which often avoids a service upgrade.
After that it becomes civil work as much as electrical. Getting power out to the stalls means trenching or core drilling, conduit under paving, bollards or wheel stops for physical protection, mounting heights and clearances, and coordination with striping and accessible stall layout. Level 2 stations run on standard branch circuits and fit workplaces, tenants, and overnight parking, while direct current fast charging needs three-phase power at much higher capacity and often its own pad plus utility work.
How many EV chargers can a building add without upgrading the service?
It comes down to spare capacity in the load calculation. Charging is a continuous load, so the math is not generous, but energy management equipment lets a site be sized on maximum simultaneous draw rather than the total of all nameplates, which can multiply the number of ports a given service supports.
What is the difference between Level 2 and DC fast charging for a commercial property?
Level 2 runs on ordinary branch circuits and suits vehicles parked for hours, so it fits offices, apartments, and hotels. DC fast charging draws far more, typically needs three-phase service at high capacity, an equipment pad, and frequently utility transformer work, so it fits retail and corridor sites where drivers stop briefly.
What should be installed now if chargers are coming later?
Conduit and pull strings to the future stalls, stub-ups placed before paving or concrete, panel space held open, and a feeder sized for the eventual count. Underground work is cheap while the ground is open and expensive once the lot is finished.
