Why laundromat electric bills look different from residential ones
Commercial laundromats sit on small-business rate schedules that bill both consumption and, in many territories, demand. Your store runs far longer than a typical retail shop: CLA's 2024 member survey reports a mean of 16.6 hours open per day, with 18% of respondents open 24 hours. That extended schedule stacks washer cycles, electric water heating, lighting, HVAC, and exhaust fans across more hours, which can push both kWh totals and short-interval kW peaks.
Dryers themselves are often gas-fired. California IOU test data for a 30-pound gas dryer averaged 0.35 kWh per load versus 0.36 therm of gas—about 96.8% of that dryer's energy from gas. Even so, the electric side of the operation remains material because EPA WaterSense notes that water heating can account for roughly 90% of a commercial washer's operating energy, and DOE data place water heating at about 50% of primary energy in the commercial laundry category.
Top-of-bill fields to verify first
Before analyzing costs, confirm the bill belongs to your store. Match the service address, account number, and meter number to what is installed on-site. Note the billing period—partial months distort comparisons. Record the rate schedule or tariff code; laundromats are frequently classified under general commercial or small general service, but the exact name varies by utility.
If your territory allows retail electric choice, the bill may list a supplier or REP separate from the delivering utility. EIA explains that in choice states the utility still delivers power even when you buy supply elsewhere.
- Account and premise ID tie the bill to your lease or deed.
- Meter number must match the physical meter; multi-meter sites need each read tracked.
- Rate schedule determines whether demand, time-of-use, or flat energy charges apply.
- Billing days count affects per-day comparisons across months.
Energy (kWh) versus demand (kW)
Kilowatt-hours measure total electricity consumed over the billing period—every washer fill, booster heater, light, and vending machine adds to this total. Kilowatts on a demand line reflect your highest average draw during a defined interval, not cumulative use. Oncor's tariff materials describe demand as commonly based on the highest 15-minute kW interval; Pepco's District of Columbia example uses a 30-minute interval for general service large volume accounts at or above 25 kW.
For a laundromat, demand spikes often coincide with overlapping washer extraction, electric water heater recovery, and HVAC on hot afternoons—not necessarily when every dryer runs, since those may be on gas. Stores above utility-specific kW thresholds may move to mandatory demand billing; Oncor notes accounts above 10 kW can shift to a demand rate schedule.
| Label on bill | Unit | What it measures |
|---|---|---|
| Energy charge / kWh | kWh | Total electricity used in the billing period |
| Demand charge / kW | kW | Highest interval average power draw |
| Customer charge | Flat $ | Fixed monthly service fee unrelated to use |
| Power factor (if shown) | Ratio | Efficiency of reactive load—relevant if many motors |
Supply, delivery, taxes, and riders
Supply charges cover generation and energy commodity costs—either from your regulated utility or an alternate supplier. Delivery charges recover wires, transformers, and local distribution; Oncor's 'Delivery Charges 101' materials treat these as regulated TDU costs separate from energy supply in Texas. Taxes, franchise fees, and tariff riders appear as separate lines and can change mid-year without a rate case you noticed.
Do not confuse procurement (choosing a supplier or contract price) with consumption reduction (equipment upgrades, scheduling, or leak fixes). This bill reading exercise identifies what you were charged; cutting kWh or kW is a different lever than renegotiating supply.
Laundromat bill review checklist
Use this sequence each month before paying or before calling your broker or utility.
- Confirm billing period length and match to store hours and season.
- Compare kWh and kW to the same month last year, not just last month.
- Check read type: actual versus estimated.
- Reconcile meter multiplier if CT/PT metering is present.
- Identify new riders, credit adjustments, or late fees.
- Separate supply dollars from delivery dollars when both appear.
- File PDFs by account number for resale or refinance due diligence.
