Texas has over 7,700 grocery stores, and few businesses are as electricity-hungry: coolers, freezers, and refrigerated cases run 24/7 and can account for roughly half of a store's power bill. This guide covers what grocers of different sizes pay, where the power goes, and how to cut it. See related guides for convenience stores and gas stations, or browse all commercial electricity guides by business type.
Key Takeaways
- A mid-size Texas grocery store uses about 40,000–70,000 kWh a month (roughly $3,300–$5,800 at ~8.3¢/kWh); full supermarkets use several times more.
- Refrigeration is 40–50% of the electric bill and runs around the clock.
- Grocery stores use roughly 45–50 kWh per square foot per year - among the highest of any retail.
- Demand charges add up because compressors, HVAC, and lighting all run together.
- Refrigeration upkeep, doors/curtains on cases, LED, and a fixed rate are the biggest levers.
The Numbers on Grocery Store Power
Figures are estimates that scale sharply with store size and refrigeration. See methodology below.
What It Costs to Keep a Grocery Store Running
Grocery electricity scales with square footage and how much refrigeration a store runs. At roughly 45–50 kWh per square foot per year, a mid-size store uses far more power than most businesses its size - and a full supermarket with extensive frozen and fresh departments is in a league of its own.
Estimated usage & bill by store size
| Store size | Approx. sq ft | Monthly usage | Est. monthly bill* |
|---|---|---|---|
| Small grocery / market | ~5,000 | 15,000–25,000 kWh | $1,250–$2,100 |
| Mid-size grocery | ~15,000 | 40,000–70,000 kWh | $3,300–$5,800 |
| Full supermarket | 35,000+ | 120,000–200,000+ kWh | $10,000–$16,000+ |
*Electricity portion at Texas's ~8.3¢/kWh average commercial rate. Stores with large frozen-food and fresh departments land at the high end.
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.
Refrigeration Rules the Grocery Bill
On the electric side nothing comes close to refrigeration, which never turns off. Cooling, lighting, and in-store food production make up most of the rest.
| System | Why it draws power | Approx. share | Est. cost / month* |
|---|---|---|---|
| Refrigeration | Coolers, freezers, and cases running 24/7 | 40–50% | $1,800–$2,250 |
| HVAC | Cooling the sales floor (fighting case heat) | 15–20% | $675–$900 |
| Lighting | Sales floor, cases, and exterior | 12–18% | $540–$810 |
| Food production (deli, bakery) | Ovens, prep, and hot cases where electric | 8–12% | $360–$540 |
| Checkout, controls & other | POS, motors, and building systems | 5–10% | $225–$450 |
*Illustrative split of a ~$4,500/month mid-size grocery bill. Open refrigerated cases without doors push refrigeration's share higher.
Why Grocery Demand Charges Add Up
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 night curtains to open cases so compressors cycle less.
- Stage refrigeration and HVAC with controls so they don't all peak together.
- Keep condensers clean - dirty coils make compressors run longer and harder.
- Watch your interval data to see exactly when the monthly peak lands.
Earning Credits Without Risking the Cold Chain
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.
Where Grocers Trim Their Energy Costs
- Lock in a fixed commercial rate. Comparing 30+ Texas providers at the right time is usually the biggest single lever.
- Put doors on refrigerated cases. Doored cases and night curtains sharply cut your largest 24/7 load.
- Maintain refrigeration. Clean coils, tight seals, and correct settings keep compressors from overworking.
- Switch to LED - including in cases. LED sales-floor and case lighting cut energy and add less heat for refrigeration to fight.
- Add refrigeration & HVAC controls. Anti-sweat heater controls, floating head pressure, and smart thermostats save meaningfully.
- 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 grocery store use in Texas?
A mid-size Texas grocery store typically uses about 40,000 to 70,000 kWh per month, or roughly $3,300 to $5,800 at the state's average commercial rate of about 8.3¢ per kWh. Small markets use far less and full supermarkets use several times more.
What uses the most electricity in a grocery store?
Refrigeration is by far the largest load - coolers, freezers, and refrigerated cases run 24/7 and make up about 40 to 50% of the electric bill - followed by HVAC, lighting, and in-store food production such as deli and bakery.
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 grocery store lower its electricity bill?
The biggest levers are locking in a competitive fixed rate, putting doors and night curtains on refrigerated cases, keeping refrigeration well maintained, switching to LED (including in cases), and adding refrigeration and HVAC controls.
Why are demand charges significant for grocery stores?
A demand charge is billed on your single highest peak of power draw in kilowatts. When refrigeration compressors, HVAC, and full lighting run together on a hot afternoon, the peak is high, and the demand charge bills it across the whole month.
What is demand response and can a grocery store earn from it?
Demand response pays businesses to reduce electricity use during short grid-peak windows. A grocer can leave refrigeration untouched while pre-cooling the sales floor and easing HVAC and lighting for a couple hours in exchange for bill credits.
