Texas is home to over 4,200 auto dealerships, and their electricity bills span three very different areas: a glass showroom that fights the Texas heat, a lot lit brightly all night for security and display, and a service department full of compressors and lifts. Below is what dealerships typically use and pay, where the power goes, and how to lower it.

Key Takeaways
- A typical franchise dealership (~13,000 sq ft of conditioned space) uses about 10,000–15,000 kWh a month, or roughly $850–$1,300 at Texas rates.
- Dealerships average about 10 kWh per square foot per year of conditioned space, before lot lighting.
- HVAC (about 40%) and all-night lot lighting (15–25%) are the two biggest costs.
- Large multi-line stores and auto malls can spend $2,500–$5,000+ a month.
- LED lot lighting on timers/photocells, high-efficiency HVAC, and a competitive fixed rate deliver the biggest savings.
The Average Auto Dealership's Electricity, at a Glance
Figures are estimates for a typical franchise store. See methodology and sources at the bottom of the page.
What Does an Auto Dealership Spend on Electricity?
Dealership electricity use scales with square footage, how much glass the showroom has, and how brightly the lot is lit. As a benchmark, dealerships run about 10 kWh per square foot per year of conditioned space. A ~13,000-square-foot franchise store therefore uses roughly 130,000 kWh a year - about 10,000 to 15,000 kWh a month once lot lighting is included.
Estimated usage & bill by dealership size
| Dealership size | Approx. sq ft | Monthly usage | Est. monthly bill* |
|---|---|---|---|
| Small used-car lot / showroom | ~5,000 | 4,000–6,000 kWh | $350–$550 |
| Typical franchise store | ~13,000 + lot | 10,000–15,000 kWh | $850–$1,300 |
| Large multi-line / auto mall | 30,000+ | 30,000–60,000+ kWh | $2,500–$5,000+ |
*Energy portion at Texas's ~8.3¢/kWh average commercial rate, based on ~10 kWh/sq ft/yr of conditioned space plus lot lighting. On-site body/paint shops and EV fast chargers add more.
How does the Texas commercial rate compare?
Texas businesses pay an average of about 8.3¢ per kWh - roughly 38% below the U.S. commercial average of ~13.5¢. A dealership's actual rate depends on its ZIP code, utility (TDU), and when it signs; because Texas is deregulated you can shop 30+ providers. Compare current commercial electricity rates.
Where the Power Goes: A Dealership's Biggest Energy Users
Cooling and lighting dominate a dealership's electric bill. Knowing the split shows where efficiency upgrades - and demand-charge control - pay off fastest.
| System | Why it draws power | Approx. share | Est. cost / month* |
|---|---|---|---|
| HVAC (showroom + offices) | Cooling big glass showrooms through the Texas heat | 35–45% | $350–$450 |
| Lot & exterior lighting | Runs all night for security and display | 15–25% | $150–$250 |
| Showroom & service lighting | Bright display and work lighting | 10–15% | $100–$150 |
| Service department | Compressors, lifts, exhaust, power tools | 10–15% | $100–$150 |
| Office, electronics & EV charging | Computers, signage, growing EV chargers | 8–12% | $80–$120 |
*Illustrative split of a ~$1,000/month bill for a typical franchise store. Body shops and on-site EV fast chargers shift the mix - and the total - higher.
Demand Charges: The Part of the Bill Most Owners Miss
Most of your bill is energy — the total kilowatt-hours (kWh) you use over the month. But many commercial accounts also carry a demand charge, billed on your single highest peak of power draw, measured in kilowatts (kW), usually over a 15-minute interval. It doesn't matter only how much electricity you use, but how fast you use it at your busiest moment.
How to keep demand charges down
- Pre-cool the showroom earlier in the day to soften the afternoon HVAC surge that sets the peak.
- Stage rooftop units so they don't all start together after a setback.
- Manage EV charger demand - networked chargers can cap or stagger charging to avoid new peaks.
- Watch your interval data to see exactly when your monthly peak happens.
Demand Response: Getting Paid to Ease Off at Peak
Demand response is a program where businesses agree to reduce their electricity use for short windows when the Texas grid (ERCOT) is under strain — typically late afternoons on the hottest summer days. In exchange, participating businesses earn payments or bill credits.
Ways Auto Dealerships Lower Their Electricity Costs
- Lock in a fixed commercial rate. Shopping 30+ Texas providers at the right time is usually the single biggest lever.
- Switch lot lighting to LED with controls. LED pole and canopy lights on photocells and timers cut a load that runs all night.
- Upgrade to high-efficiency HVAC. Right-sized rooftop units, economizers, and smart thermostats tame the biggest cost.
- Manage EV charging. Networked chargers can stagger sessions so they don't create new demand peaks.
- Seal and shade the showroom. Low-e glass film and good sealing reduce the cooling load from all that glazing.
- Review your demand and interval data. Knowing your peak kW tells you whether a different rate structure would save money.

Frequently Asked Questions
How much does electricity cost for a car dealership in Texas?
A typical franchise dealership of about 13,000 square feet uses roughly 10,000 to 15,000 kWh per month and pays about $850 to $1,300 at Texas's average commercial rate of about 8.3¢ per kWh. Small used-car lots pay less, while large multi-line stores and auto malls can spend $2,500 to $5,000 or more a month.
What uses the most electricity at an auto dealership?
HVAC is usually the largest cost - cooling big glass showrooms through the Texas heat can be 35 to 45% of the bill - followed by all-night lot and exterior lighting at 15 to 25%. Showroom and service lighting, the service department, and office/EV-charging loads make up the rest.
What is the average commercial electricity rate in Texas?
Texas businesses pay an average of about 8.3¢ per kWh as of 2026, roughly 38% below the U.S. commercial average of about 13.5¢. Your actual rate depends on your ZIP code, utility (TDU), usage, and when you sign your contract.
How can a dealership lower its electricity bill?
The highest-impact steps are locking in a competitive fixed commercial rate, switching lot lighting to LED on photocells and timers, upgrading to high-efficiency HVAC, and managing EV-charger demand so it doesn't create new peaks.
What is a demand charge on a dealership's electric bill?
A demand charge is billed on your single highest peak of power draw, measured in kilowatts (kW) over a short interval such as 15 minutes, rather than on total kWh. When rooftop HVAC units and service compressors run together on a hot afternoon, the peak can be high; at $5 to $15 per kW, a 60 kW peak can add $300 to $900 to a bill.
What is demand response and can a dealership earn from it?
Demand response pays businesses to reduce electricity use during short grid-peak windows, usually hot summer afternoons. A dealership with large HVAC and EV charging can pre-cool, raise setpoints slightly, and pause fast-charging during a 2 to 4 hour event in exchange for payments or bill credits.
