Texas has over 3,900 convenience stores, and they pack extraordinary energy use into a small footprint - refrigeration alone is about 55% of the electric bill. This guide covers what c-stores use and pay, and where the power goes. See related guides for gas stations and grocery stores, or browse all commercial electricity guides by business type.
Key Takeaways
- A typical Texas c-store uses about 10,000–25,000 kWh a month (roughly $850–$2,100 at ~8.3¢/kWh).
- Convenience stores run about 52.5 kWh per square foot per year - very high for their size.
- Refrigeration is ~55% of the electric bill; lighting is another ~22%.
- Stores with foodservice and 24-hour operations use the most.
- Refrigeration upkeep, LED (interior and canopy), and a fixed rate deliver the biggest savings.
C-Store Electricity, in Brief
Figures are estimates; usage scales with refrigeration, hours, and foodservice. See methodology below.
The Cost of Powering a C-Store
At about 52.5 kWh per square foot per year, a convenience store uses several times the power of a typical retail space its size. The reason is simple: walls of coolers and freezers running non-stop, bright lighting inside and under the canopy, and often a foodservice program on top.
Estimated usage & bill by store size
| Store size | Approx. sq ft | Monthly usage | Est. monthly bill* |
|---|---|---|---|
| Small c-store | ~2,000 | 8,000–14,000 kWh | $650–$1,150 |
| Typical c-store | ~3,000 | 12,000–20,000 kWh | $1,000–$1,650 |
| Large / 24-hr w/ foodservice | 4,500+ | 20,000–35,000+ kWh | $1,650–$2,900+ |
*Electricity portion at Texas's ~8.3¢/kWh average commercial rate. Stores attached to fuel islands also carry canopy and dispenser loads (see the gas-station guide).
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¢. Because Texas is deregulated, you can shop the supply portion of your bill across 30+ retail providers and lock in a fixed rate - compare current commercial electricity rates.
Coolers First: A C-Store's Biggest Loads
Refrigeration dominates a convenience store's electric bill like almost nowhere else, with lighting a distant second. Both run long hours, which is what sets the demand peak.
| System | Why it draws power | Approx. share | Est. cost / month* |
|---|---|---|---|
| Refrigeration | Coolers, freezers, and beverage cases 24/7 | 50–55% | $650–$715 |
| Lighting (interior + canopy) | Bright display and 24-hour canopy lighting | 18–22% | $235–$285 |
| HVAC | Cooling the store, fighting case heat | 8–12% | $105–$155 |
| Foodservice | Coffee, roller grills, warmers, fountains | 5–8% | $65–$105 |
| POS, controls & other | Registers, pumps, building systems | 5–8% | $65–$105 |

How Compressors and Coolers Set Your Peak
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
- Add doors and strip curtains so compressors cycle less.
- Keep condenser coils clean so refrigeration doesn't overwork in the heat.
- Switch canopy and interior lighting to LED to cut a big always-on load.
- Watch your interval data to find the monthly peak.
Demand Response for Around-the-Clock Stores
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.
Cutting a Convenience Store's Electric Bill
- Lock in a fixed commercial rate. Comparing 30+ Texas providers at the right time is usually the biggest single lever.
- Door your coolers and add controls. Doors, night curtains, and anti-sweat heater controls cut your dominant load.
- Maintain refrigeration. Clean coils and tight seals keep compressors efficient.
- LED everything, including the canopy. Canopy and interior LEDs run 24/7 - the savings compound.
- Tune foodservice equipment. Turn off idle warmers and grills; use timers on coffee and fountains.
- Review demand and interval data. Knowing your peak kW shows whether a different rate structure would save money.

Frequently Asked Questions
How much electricity does a convenience store use in Texas?
A typical Texas convenience store uses about 10,000 to 25,000 kWh per month, or roughly $850 to $2,100 at the state's average commercial rate of about 8.3¢ per kWh. Convenience stores average about 52.5 kWh per square foot per year, very high for their size.
What uses the most electricity in a convenience store?
Refrigeration is about 55% of the electric bill because coolers and freezers run around the clock. Lighting (interior and canopy) is another 22% or so, followed by HVAC and foodservice equipment.
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 convenience store lower its electricity bill?
Lock in a competitive fixed rate, add doors and anti-sweat heater controls to coolers, keep refrigeration maintained, switch interior and canopy lighting to LED, and put timers on idle foodservice equipment.
Do convenience stores pay demand charges?
Often yes. When cooler and freezer compressors, HVAC, and lighting run together on a hot afternoon, they create a peak in kilowatts that a demand charge bills across the whole month, so managing that peak lowers the bill.
What is demand response and can a c-store earn from it?
Demand response pays businesses to reduce electricity use during short summer grid-peak windows. A c-store can keep refrigeration on while easing HVAC and trimming non-essential lighting for a short window in exchange for bill credits.
