What fixed supply pricing actually fixes
A fixed-price retail supply contract locks the energy commodity rate—or defined formula—for the contract term on eligible meters. It does not replace your utility relationship or eliminate delivery line items billed per the regulated tariff.
EIA FAQ 627 reminds customers that utilities continue delivering after supplier switches. Those delivery costs change when regulators approve tariff updates—not when you fix supply price.
Variable components to model separately
Build budgets with explicit line items rather than one blended number.
| Component | Typically fixed via supply contract? | Typical variability driver |
|---|---|---|
| Retail energy $/kWh | Yes, if fixed contract | Renewal price at term end |
| Delivery $/kWh and $/kW | No—utility tariff | Regulatory rate cases; your peak kW |
| Gas supply $/therm | Partially in choice markets | Index structures; basis changes |
| Riders and taxes | Mostly pass-through | Regulatory additions |
| Total spend | No | Usage volume × rates + demand |
Demand and consumption uncertainty
Oncor documents 15-minute interval demand billing above certain kW thresholds; Pepco DC examples use 30-minute intervals at or above 25 kW. Even with fixed supply rates, a month with higher peak kW raises delivery demand charges.
Operational changes—more hot cycles, extended summer hours, added stores—increase kWh and possibly kW regardless of supply contract type.
Budget planning practices
Owners seeking certainty should pair fixed supply terms with operational monitoring of peak kW and therms—not assume one contract eliminates variance.
- Model best/base/high scenarios for kWh, therms, and peak kW.
- Identify contract renewal dates as budget reset points.
- Track effective $/kWh and $/therm monthly from actual bills.
- Separate supply savings hypotheses from delivery tariff updates.
- Review bandwidth clauses that add cost if usage exceeds contract levels.
Effective all-in electric cost
Effective $/kWh = total electric bill ÷ total kWh
Units: $/kWh
Includes supply and delivery; useful for budget tracking, not supplier comparison alone.
Building a rolling energy budget
Use trailing twelve-month effective $/kWh and $/therm multiplied by expected usage for base budget. Add line for known tariff rider changes announced by utility. Add scenario band for usage plus or minus ten percent.
Separate supply renewal dates on budget calendar—fixed supply rate expires even when operations stable. Renewal month resets supply portion of budget.
Compare budget to actual monthly; investigate variances over ten percent promptly—rate change, usage change, or meter read anomaly.
Communicating budget limits internally
Staff thermostat adjustments and hot water setpoint overrides affect consumption against budget—not supply rate. Train managers on which levers affect kWh and therms without touching procurement contracts.
Investors in multi-store portfolios expect energy as percent of revenue tracking. CLA utility cost concern data supports treating energy as first-class budget line, not miscellaneous.
Capital projects—LED, extraction washers—should include post-install measurement milestone in budget notes to verify consumption impact before next procurement cycle.
Applying this guidance at your laundromat
Start with a written baseline: twelve months of utility bills for each meter, vend counts or card-system totals for the same period, and an equipment inventory listing washer and dryer model numbers, water heater or boiler type, and approximate install year. This guide targets the query laundromat energy budget certainty for U.S. coin laundry owners.
The core question here is specific: Owner must know which bill components can be fixed via procurement and which stay variable on utility tariff. Use that sentence as a checklist header and verify each item against your store's actual bills, contracts, and maintenance records—not assumptions from another market.
Content focus: Honest bounds on predictability—fixed supply vs variable delivery components. Coin Laundry Association 2024 survey data reports mean operating hours of 16.6 per day and notes that 53% of members rank utility costs among their top business concerns—measurement and documentation therefore deserve the same discipline as cash reconciliation.
Separate supply procurement from the other side of the bill. The U.S. Energy Information Administration FAQ on retail choice explains that supplier selection does not change the regulated utility's delivery role; municipal utilities and cooperatives are often excluded from competitive supply entirely.
Schedule review by 2027-03-12 or sooner if you replace major equipment, change operating hours, add a store, or receive a utility rate-case decision affecting delivery charges. Update relatedGuideSlugs topics in your internal playbook when those events occur.
Keep a single folder—physical or cloud—per store with the last three years of utility PDFs, supply contracts, letters of authorization, combustion test reports, and lint duct cleaning invoices. Future buyers, lenders, and your own renewal negotiations all move faster when records are complete.
When sharing data with brokers or suppliers, redact unrelated account numbers but preserve meter identifiers and rate class labels exactly as printed on the utility bill. Errors in those fields delay switches in choice markets and produce quotes that do not bind to your actual service point— wasting the notice windows described in many commercial supply contracts.
- Verify rate class and meter identifiers on bills match supplier and broker files for energy budget certainty for laundromats.
- Compare month-over-month usage at similar vend counts before attributing bill changes to rates alone.
- Note whether your territory uses interval demand billing and request interval data if peaks are unknown.
- Document who authorized any contract signature, thermostat change, or setpoint adjustment with date.
- Re-read parent topic context under Energy procurement or Energy consumption before mixing shopping with efficiency projects.
- If interval demand data is available, chart the highest kW intervals against store video or POS timestamps to identify repeatable peak drivers.
- Contact your utility account representative once per year to confirm rate schedule name, demand threshold, and any pending tariff riders—even when you are not switching supply.
- Note whether bills combine supply and delivery on one page or separate sections—comparison errors are common when statement formats change between renewal cycles or after supplier switches.
