How much does it cost to charge an EV at home in Queensland? (Real 2026 numbers)

"How much will it cost me to charge at home?" is question three, right after "which charger should I get?" and "does my switchboard need upgrading?" Most EV owners underestimate home charging costs at first, then realise they're still paying a fraction of what petrol cost them.

Here are the real numbers for Queensland in 2026.

QLD electricity tariffs relevant to EV charging

Queensland electricity pricing (via Energex distribution, retailer prices vary slightly):

Tariff 11 (General Supply, the standard residential tariff):

• Peak: approximately 30-33c/kWh depending on retailer.
• Most flat-rate residential plans are in this range for all usage.
• If you plug your EV in at 6pm after work, you're on this rate.

Tariff 12 (Time of Use):

• Peak (typically 4pm-9pm weekdays): 42-46c/kWh.
• Shoulder: 23-27c/kWh.
• Off-peak: 18-22c/kWh.
• If you're on a Time of Use plan and charging at peak time, you're paying significantly more. Switch to overnight charging or change tariff.

Tariff 33 (Controlled Load, off-peak):

• Approximately 18-22c/kWh, controlled by Energex via ripple signal (usually available 10pm-7am, varies by night and area).
• The EV charger must be connected via a separately metered Tariff 33 circuit, with an approved load controller. Not all chargers are compatible with Tariff 33 wiring.
• Installation adds roughly $350-$550 for the separate circuit and ripple receiver. Worth it if you charge a full battery every night.

Solar self-consumption (not a tariff, but the best deal in the house):

• Feed-in tariff in SE QLD: approximately 5-6c/kWh.
• Import rate: 30-33c/kWh.
• Every kWh of surplus solar that charges your EV instead of going to the grid saves you 24-27c/kWh compared to buying from the grid at peak.
• With a Zappi or Ocular in Eco mode, this happens automatically during the day.

Charging with solar: what it actually saves

Let's run the numbers for a typical Camp Hill household with a 6.6kW solar system and a Tesla Model 3:

• Daily solar generation (annual average, Brisbane): approximately 26kWh.
• Household daytime consumption (you're at work): approximately 4kWh.
• Solar surplus available for EV charging: approximately 22kWh on a good day, 8-10kWh on average including cloudy days.
• Model 3 Long Range battery: 75kWh. You rarely charge from flat; daily top-up is typically 10-20kWh.

On a 5-day work week, assume you return with 40-60km of range used per day = roughly 8-12kWh to replace. Your daytime solar surplus on a Brisbane weekday covers that comfortably in Eco mode.

Annual saving from solar-divert charging vs grid charging:

• 10kWh per day x 250 working days = 2,500kWh per year.
• At 25c/kWh saved (grid import avoided): $625/year.
• On a Zappi, the hardware premium over a basic charger ($600) pays back in about 12 months from the solar divert alone.

Real cost per 100km

Actual cost per 100km of EV driving depends on the car's efficiency and the tariff. Here are realistic 2026 Brisbane numbers:

| Scenario | Cost/kWh | Cost/100km (Tesla M3, 6.5km/kWh) | |----------|----------|----------------------------------| | Grid (Tariff 11, off-peak) | 22c | $3.38 | | Grid (Tariff 11, peak) | 32c | $4.92 | | Grid (Tariff 33, controlled load) | 20c | $3.08 | | Solar self-consumption | ~5c effective | $0.77 | | Solar surplus divert (Zappi Eco+) | ~2-3c effective | $0.30-$0.46 |

For comparison, a Toyota Corolla at 7L/100km and $2.00/L petrol costs $14/100km.

Even on peak tariff, home EV charging is one-third the cost of petrol. On off-peak or solar, it's the difference between $3.50 and $14.00 for the same 100km.

Home vs public charging: the true comparison

Public DC fast charging (Chargefox, Tesla Supercharger, Evie) in QLD runs roughly $0.42-$0.52/kWh as of mid-2026. At 6.5km/kWh efficiency, that's $6.46-$8.00 per 100km. Faster than home but 2-3x the cost.

The economic case for a home charger:

• If you drive 15,000km/year, you use approximately 2,300kWh of charging.
• Home vs public DC: saves roughly $70-$120 per 100km x 150 = $1,050-$1,800/year.
• A home charger install (mid-range Zappi, new 32A circuit) costs $2,400-$2,950 all-in.
• Payback on the charger from avoided public charging: 1.5-3 years.

This is why home charging is worth the install cost for anyone driving more than 8,000km/year.

The best charging window in Brisbane

In order of cost-effectiveness:

1. Solar hours with Eco/Eco+ mode (10am-3pm): Best option. Free surplus, no grid draw.
2. Scheduled off-peak (10pm-7am) on Tariff 33: 18-22c/kWh. Good for overnight top-up.
3. Scheduled off-peak on Tariff 11 or 12 (any plan with off-peak): 18-22c/kWh. Set a schedule in the charger app to avoid peak windows.
4. Unscheduled peak charging (4pm-9pm on TOU): Avoid. 42-46c/kWh. Only useful in a genuine emergency.

Most smart chargers (Zappi, Ocular, Tesla) allow schedule programming. Set the schedule once, forget it. The car will be full by morning at off-peak rates.

What I recommend

For a Brisbane homeowner getting their first EV charger:

1. Get Tariff 33 if you can: Ring your retailer, ask them to set up Tariff 33 on a sub-meter for the EV circuit. The Energex ripple receiver adds $350-$550 to the install but the overnight rate is the cheapest grid power available.
2. If you have solar, get a Zappi or Ocular: The solar divert pays for the hardware premium within 12-18 months. See the EV charger comparison guide for the detailed breakdown.
3. Don't charge at peak time: This sounds obvious but a lot of people plug in when they get home from work (5pm-8pm) and that's exactly when Time of Use rates are at maximum. Set a schedule.
4. Get a 32A circuit, not a 16A: Even if your current car only draws 16A (7.4kW), a 32A rated circuit and cable costs about $80-$120 more to install and future-proofs you for a higher-capacity vehicle.

For EV charger installation anywhere in the inner east Brisbane area, ring 0411 054 811. I'll come out, assess your switchboard and metering setup, and give you a fixed price for the complete install.
