Frequently Asked Questions

How much does it cost to charge an EV at home in Ontario?

The cost depends on your rate plan and how much you drive. On the Ultra-Low Overnight plan, charging at 2.8c/kWh plus delivery charges, a typical EV driven 16,000 km/year costs about $25-45 per month. On Time-of-Use (off-peak at 7.6c/kWh), expect $50-80 per month. This is significantly less than the $150-250/month most drivers spend on gasoline.

Which Ontario electricity plan is cheapest for EV charging?

The Ultra-Low Overnight (ULO) plan is by far the cheapest for EV owners. It charges just 2.8c/kWh during overnight hours (11 PM - 7 AM), which is when most people charge their EVs at home. This can be 60-70% cheaper than charging on the Tiered plan. If you own an EV, switching to ULO is one of the best ways to reduce your charging costs.

How much does it cost to drive an EV per 100 km vs gas?

An electric car costs roughly $1.50-3.50 per 100 km in electricity (depending on your rate plan), compared to $10-18 per 100 km for a gas vehicle (at $1.47/L). That means driving an EV is about 75-85% cheaper per kilometre than driving a gas car in Ontario.

How many kWh does it take to charge an electric car?

It depends on how far you drive. Most EVs consume 16-21 kWh per 100 km. If you drive 16,000 km per year, you will need approximately 2,560-3,360 kWh per year for charging, or about 213-280 kWh per month. A typical Ontario household uses about 750 kWh/month, so an EV adds roughly 30-40% to your electricity consumption.

Can solar panels cover my EV charging?

Yes. In Ontario, 1 kW of solar panels produces approximately 1,050-1,200 kWh per year. To offset a typical EV's annual charging needs (3,000-4,000 kWh), you would need a 3-4 kW solar system, costing approximately $8,500-11,400 installed. Combined with net metering, solar can effectively eliminate your EV charging costs.

Is it cheaper to charge at home or at a public station?

Home charging is significantly cheaper. Public DC fast chargers in Ontario typically cost 35-55c/kWh, compared to 2.8-10.3c/kWh at home (depending on your rate plan). That means public charging can be 4-10 times more expensive than home charging. Most EV owners do 90%+ of their charging at home overnight.
