Will My Electric Bill Increase With a Wall Charger?
April 26, 2026
Yes, your electric bill will go up. But here's the number that matters: most Orlando area EV owners we work with see an increase of $30 to $60 per month. That's it. Compare that to the $150 to $250 they were spending on gasoline, and the math speaks for itself.
We install wall chargers across Central Florida every week, and the electricity cost question comes up on nearly every job. So we've put together a thorough breakdown with real Florida utility rates, actual vehicle consumption numbers, and strategies our customers use to keep that bill as low as possible.
How Much Electricity Does an EV Actually Use?
Every electric vehicle has an efficiency rating measured in kWh per 100 miles. Think of it like MPG, but for electricity. Here's what popular models consume:
- Tesla Model 3: 25 kWh per 100 miles
- Tesla Model Y: 28 kWh per 100 miles
- Chevrolet Equinox EV: 30 kWh per 100 miles
- Ford Mustang Mach-E: 33 kWh per 100 miles
- Ford F-150 Lightning: 48 kWh per 100 miles
- Rivian R1S: 45 kWh per 100 miles
The average Central Florida driver covers about 1,000 to 1,200 miles per month. Commuting from suburbs like Waterford Lakes, Lake Nona, or Winter Garden into downtown Orlando adds up fast with the daily I-4 or 408 grind.
Florida Electricity Rates: What You're Actually Paying
Your charging cost depends entirely on your utility provider and rate plan. Central Florida has several major utilities, and their rates differ more than you'd expect.
OUC (Orlando Utilities Commission)
OUC serves Orlando, St. Cloud, and parts of unincorporated Orange and Osceola counties. Their standard residential rate runs about $0.1050 per kWh for the first 1,000 kWh, then increases to around $0.1150 per kWh above that. OUC also charges a fuel adjustment that fluctuates quarterly, typically adding $0.02 to $0.04 per kWh to your effective rate. So your real rate lands between $0.12 and $0.15 per kWh depending on the month.
Duke Energy Florida
Duke covers a large swath of Central Florida including Winter Park, Maitland, Altamonte Springs, and parts of Seminole County. Their standard residential rate is approximately $0.12 to $0.14 per kWh including all surcharges. Duke also offers a time of use plan called the "Savings By the Hour" program, which we'll cover below.
TECO (Tampa Electric)
If you're on the western side of our service area near Polk County, you might be on TECO. Their rates hover around $0.12 to $0.13 per kWh for most residential customers.
Florida Co-ops and Municipals
Kissimmee Utility Authority (KUA) and other smaller municipals in the region typically charge $0.10 to $0.13 per kWh. KUA customers often get some of the lowest rates in Central Florida.
Monthly Cost Calculations by Vehicle
Let's use a blended Florida rate of $0.13 per kWh and assume 1,000 miles per month. Here's what each vehicle adds to your bill:
| Vehicle | kWh per 100 mi | Monthly kWh (1,000 mi) | Monthly Cost at $0.13/kWh | Monthly Cost at $0.15/kWh |
|---|---|---|---|---|
| Tesla Model 3 | 25 | 250 | $32.50 | $37.50 |
| Tesla Model Y | 28 | 280 | $36.40 | $42.00 |
| Chevy Equinox EV | 30 | 300 | $39.00 | $45.00 |
| Ford Mustang Mach-E | 33 | 330 | $42.90 | $49.50 |
| Hyundai Ioniq 5 | 30 | 300 | $39.00 | $45.00 |
| Ford F-150 Lightning | 48 | 480 | $62.40 | $72.00 |
| Rivian R1S | 45 | 450 | $58.50 | $67.50 |
Notice the spread. A Tesla Model 3 owner adds about $33 to their monthly bill. An F-150 Lightning owner adds about $62. That's a real difference, and it tracks with what we hear from customers.
Gas vs. Electric: The Full Cost Comparison
Numbers without context don't help much. Here's what those same monthly miles cost with gasoline at $3.40 per gallon (roughly the Central Florida average):
| Monthly Miles | Gas Cost (25 MPG) | Gas Cost (30 MPG) | EV Cost (Model Y) | EV Cost (F-150 Lightning) | Monthly Savings (Model Y) |
|---|---|---|---|---|---|
| 500 | $68.00 | $56.67 | $18.20 | $31.20 | $38 to $50 |
| 1,000 | $136.00 | $113.33 | $36.40 | $62.40 | $77 to $100 |
| 1,500 | $204.00 | $170.00 | $54.60 | $93.60 | $115 to $149 |
| 2,000 | $272.00 | $226.67 | $72.80 | $124.80 | $154 to $199 |
Even the F-150 Lightning, the thirstiest EV in this lineup, costs less than half what a 25 MPG truck burns in gas. For sedan and crossover owners, the savings are dramatic.
Time of Use Rates: The Biggest Money Saver
This is where smart EV owners really cut their bills. Time of use (TOU) rate plans charge less for electricity during off peak hours, which is exactly when you'd be charging your car anyway.
Duke Energy "Savings By the Hour"
Duke's TOU plan breaks the day into three tiers. Off peak hours (roughly 10 PM to 6 AM) drop your rate to around $0.06 to $0.08 per kWh. On peak summer afternoons can spike to $0.20+ per kWh. If you charge your EV overnight, you're paying nearly half the standard rate. That Model Y charging bill drops from $36 to about $20 per month.
OUC Residential TOU Rate
OUC offers a time of use option where off peak electricity (9 PM to 6 AM weekdays, all weekend) comes in around $0.04 to $0.06 per kWh less than peak. The savings aren't as dramatic as Duke's plan, but they're meaningful over a year. OUC also occasionally runs EV specific programs and rebates, so check their website or call them directly.
How to Set It Up
Both the Tesla app and most smart chargers (ChargePoint Home Flex, Emporia, Wallbox Pulsar Plus) let you set a charging schedule. Program it to start at 10 PM or 11 PM, and your car charges entirely on cheap overnight electricity. You set it once and forget it.
The Summer Problem: AC Plus EV Charging
Here's something specific to Florida that catches people off guard. Your air conditioner is your biggest electricity consumer, and it runs hardest from May through October. A typical Central Florida home uses 1,200 to 1,800 kWh per month in summer versus 700 to 900 kWh in winter.
Add 250 to 480 kWh of EV charging on top of peak summer AC usage, and you might push into a higher rate tier with some utilities. OUC's tiered rate structure means those extra kWh above 1,000 cost more per unit.
A customer in Winter Park with a Model Y told us their summer electric bills went from $180 to about $225 after adding a Level 2 charger. In January, the same household saw bills go from $95 to $130. The charger added roughly the same amount each month, but the summer bill felt larger because the base was already high.
The fix is straightforward: charge during off peak hours in summer. Your AC is already pulling heavy amps during afternoon peak times. Don't stack EV charging on top of it.
Solar Panel Integration
Central Florida averages 233 sunny days per year. That makes solar a natural pairing with EV charging, and we see this combination more and more on installations.
How the Math Works
A typical residential solar system in Orlando produces 1,200 to 1,500 kWh per month. If your home uses 1,100 kWh and your EV adds 300 kWh, you need a system that covers about 1,400 kWh. A 9 to 10 kW system handles that comfortably in Central Florida's sunshine.
Net Metering
Florida's net metering rules let you bank excess solar production during the day and use those credits overnight when your EV charges. You produce power while you're at work, and the meter effectively runs backward. At night, your charger draws from the grid, but your daytime credits offset that cost.
With a properly sized solar system, your EV charging cost can drop to effectively zero. We've installed chargers for customers in Lake Nona and Horizon West who paired them with new solar installations and saw their total electric bills actually decrease compared to pre EV, pre solar levels.
Without a Battery
You don't need a home battery like a Tesla Powerwall to make solar work with EV charging. Net metering handles the timing mismatch. Batteries add resilience for power outages, but they're not required to offset your charging costs.
Smart Charger Energy Monitoring
One of the most practical features of a Level 2 smart charger is energy tracking. You can see exactly how much electricity your car consumes, down to the session.
What Smart Chargers Track
- kWh per charging session: Know exactly what each charge costs
- Monthly and yearly totals: Track trends over time
- Cost calculations: Input your rate and see dollar amounts
- Charging schedules: Verify your off peak timing is working
The Tesla Wall Connector shows this data in the Tesla app. The ChargePoint Home Flex has its own app with detailed energy reports. Emporia's smart charger integrates with their whole home energy monitoring system, which is especially useful if you want to see your EV's share of total household consumption.
We recommend reviewing your charger data alongside your first couple of utility bills after installation. It helps you understand exactly how much the charger adds and whether your charging schedule is optimized.
Impact on Your Home's Electrical Capacity
Your electric bill isn't the only consideration. Adding a 240V charger draws significant power, and your home's electrical panel needs to support it.
Panel Capacity
A Level 2 EV charger typically requires a 50 amp or 60 amp dedicated circuit. That's a substantial load. Here's how it stacks up against your other appliances:
- EV charger (48A): 11.5 kW
- Central AC (typical Florida home): 4 to 6 kW
- Electric water heater: 4.5 kW
- Electric dryer: 5.4 kW
- Electric oven: 3 to 5 kW
Homes with a 200 amp panel generally have plenty of capacity. If your home has a 100 amp panel, which is common in homes built before the mid 1990s, you might need a panel upgrade or a load management device. We assess this during every site evaluation before quoting a price.
Load Management as an Alternative
If your panel is tight on capacity, a load management device like a DCC-9 or NeoCharge smart splitter can share a circuit between your charger and another appliance (like a dryer). This avoids a full panel upgrade and can save $1,500 to $3,000. The charger draws power when the dryer isn't running, and pauses when it is. For most people, this works seamlessly since you're not drying clothes and charging simultaneously at 2 AM.
Real Scenario: A Customer in Winter Park
Last fall we installed a Tesla Wall Connector for a couple in Winter Park who'd just picked up a Model Y Long Range. They were on Duke Energy's standard residential rate at about $0.13 per kWh. Their pre EV electric bills averaged $140 in summer, $85 in winter.
They drive about 1,100 miles a month combined (two commuters). That translates to roughly 308 kWh of charging. At $0.13 per kWh, the math says $40 per month.
After the first three months, their actual increase averaged $43 per month. Slightly higher than the raw math because Level 2 charging has about 10 to 15 percent efficiency loss from the charger and battery management system.
They were spending $220 per month on gas for two cars (one was the ICE vehicle they traded in). Net monthly savings: about $177. They switched to Duke's time of use plan three months later and dropped their charging cost to roughly $25 per month. Annual savings came out to around $2,340 compared to their previous gas spending.
Tips to Minimize Your Bill Increase
- Switch to a time of use rate plan. Call your utility. OUC and Duke both offer them. This single step can cut your charging cost by 30 to 50 percent.
- Schedule charging for off peak hours. Set it in your car's app or charger app. 10 PM to 6 AM is the sweet spot for most plans.
- Don't charge to 100% daily. Charge to 80% for daily driving. It's better for your battery and uses less electricity per session.
- Use a smart charger with monitoring. Track your usage. You'll spot patterns and optimize over time.
- Consider solar. A solar system sized for your home plus EV can eliminate your charging cost entirely. Florida's sun makes the payback period shorter than in most states.
- Avoid stacking loads in summer. Don't run your dryer, pool pump, and EV charger simultaneously during peak afternoon hours.
- Keep your EV's tires properly inflated. Low tire pressure increases energy consumption by 3 to 5 percent. In Florida heat, check monthly.
What About Level 1 Charging?
Some people ask whether using the standard 120V outlet (Level 1) would save money compared to a Level 2 wall charger. The electricity cost per mile is virtually identical. Level 1 charging is actually slightly less efficient due to longer charging times and the overhead of the vehicle's battery management system running for more hours.
The real drawback of Level 1 is speed: 3 to 5 miles of range per hour. If you drive 40 miles a day, you need 8 to 13 hours of charging. That's manageable for some people, but it doesn't save you money on electricity. It just avoids the upfront cost of a charger installation.
The Bottom Line
Your electric bill will increase by $30 to $65 per month for a typical Central Florida driver. That's real money. But you're also eliminating $120 to $250 per month in gasoline costs. The net savings run $80 to $180 per month depending on your vehicle, driving habits, and utility rate.
Switch to a time of use plan, charge overnight, and you'll reduce even that modest increase. Add solar panels and the charging becomes essentially free. Either way, the wall charger pays for itself within the first year through fuel savings alone.
