EV charging at a commercial site

The chargers are rarely the hard part. The supply is. What decides the cost of workplace charging is how much spare electrical capacity the site already has.

What it is

Sockets are installed in a car park or yard and connected back to the site supply, usually with load management so that the building and the vehicles share what is available.

The commercial case is normally staff retention, fleet operation, tenant expectation or planning, rather than a direct saving on your energy bill.

Does it suit you

It suits sites with off street parking, a fleet, or staff and visitors who park for hours rather than minutes.

It suits you less where parking is on street, where dwell time is short, or where the supply is already close to its agreed capacity and reinforcement would be needed.

What decides it
  • -Spare import capacity at the site. Charging adds load, so this is the first question and not the last.
  • -Distance from the intake to the parking, because trenching and cable are a real share of the cost.
  • -How long vehicles stay, which decides whether slow sockets will do or fast ones are needed.
  • -Who owns the car park, and what the lease says about works to it.
Cost and saving

The figures Meridians models with. Your building replaces them with its own data as soon as we have it.

Installed cost
from 1,200 to 3,200 per socket

Cost leads with the low end. Payback leads with the longer one.

Modelled from the consumption figure you gave us, so an installer survey may land elsewhere in these ranges.

  • Charging demand has not been given, so no annual saving has been produced.
What goes wrong
  • -Sockets are specified before the supply is checked, and a capacity upgrade arrives as a surprise.
  • -No load management is fitted, so the site trips or the agreed capacity is exceeded and charged for.
  • -Ducting is not laid for a second phase, so the ground is opened twice.
