Installing an EV charger

Finding the right charger is a combination of your specific needs, your home’s electrical system and the ability of your neighbourhood’s network to deliver the power.

If you live in a single-family home

Contact a certified electrician before you purchase a charger. They can help recommend which charger can work with your current electrical set up and services to your home. Your electrician should complete a load calculation to determine whether your current panel can handle the addition of an EV charger.
If your home does not have sufficient electricity supply for the EV charger of your choice, there are several options you can explore for EV charging in your home, including considering a less powerful charger, an EV Energy Management System, or upgrading the main electrical service to your home.
If the wires that supply electricity to your home are above ground, service upgrades should be covered by ENMAX. You will be charged a disconnect/reconnect fee ($300).
Upgrades to buried wires on your property need to be paid for by the homeowner and can be expensive. If you have an underground service, we recommend investigating other, cost-effective ways to integrate EV charging into your home, before you commit to a service upgrade.

If you live in an apartment or condominium

Contact your landlord or condominium board before purchasing or installing a charger. They will typically need to approve any installations or may be considering adding chargers.
If you cannot install an EV charger at your condo, you can consider the following:

  • Use a Level 1 or trickle charger using 120V outlet to trickle charge your vehicle
  • If possible, see if public charging locations are available in your area.

Connect with right charger

Knowing your options when it comes to selecting a charger is a key to helping make sure you find the right combination of efficiency and affordability relative.

Ways to manage EV charger demand

Before making costly changes around your home or your electricity services to accommodate an EV charger’s additional demand consider these solutions.

Consider a less powerful charger

Selecting a small charger that can be supplied from the existing electrical system in your home is the lowest-cost solution, as it eliminates the need for upgrades or additional technologies. This could look like purchasing a 30 amp charger instead of a 50 amp charger. Although a smaller charger will charge your vehicle more slowly, we estimate that the average driver will require fewer than three hours of charging per night.

Manage your energy use

An EV energy management system (approx. cost $1,200) adjusts the power fed to your charger and balances it with your other appliances and demand so that you stay within the limits of your current electrical service. We recommend reaching out to your electrician for a quote of current prices.

The City of Calgary has a useful information sheet for you and your electrician about EV energy management systems.
