Electricity offer worked example: hotel operations
An explicitly hypothetical electricity comparison for hotel operations: operating assumptions, fee arithmetic and contract limits.
An illustrative hotel decision
This example is independently constructed. It does not describe a customer, property or achieved result. Its purpose is to show how an operating question and a fee can change a comparison. The figures below are assumptions, not typical usage, a benchmark or a market quote.
The operating question
Separate occupied-room demand for hot water and laundry from base ventilation, refrigeration and common-area loads. A changing occupancy pattern can alter the value of a fixed-volume assumption. Use occupied room-nights alongside energy, but do not infer that a higher unit cost means the supplier made an error.
Equipment to investigate includes guestroom HVAC, domestic hot water and laundry. The main constraints to document are occupancy changes, comfort standards and event loads. A useful activity measure may be energy per occupied room-night, provided its boundary and period remain consistent. Those records help explain the account; they do not determine supplier eligibility.
State the modeled purchase
Assume annual consumption of 600,000 kWh, identical start and end dates, and the same included cost components. Offer A has a flat rate of $0.092 per kWh and no monthly supplier fee. Offer B has a flat rate of $0.09 per unit and $65 each month in supplier fees.
| Entered component | Offer A | Offer B |
|---|---|---|
| Annual commodity amount | $55,200 | $54,000 |
| Annual recurring supplier fees | $0 | $780 |
| Modeled annual supply total | $55,200 | $54,780 |
The difference is $420 per year on the entered components. Offer B is lower in this specific model. Change the assumptions and the comparison can change. Use the offer comparison tool to reproduce the arithmetic; for a portfolio, enter the aggregate recurring fee only after checking how it is charged.
Costs and obligations outside the example
Utility delivery, demand, taxes, variable pass-throughs, deposits, promotional credits, termination and project costs are not modeled. Both agreements would need the same inclusions for the totals above to be a fair comparison. An apparently lower modeled cost is not a recommendation to sign.
For an electric offer, verify capacity, transmission, losses and demand treatment. A supply-rate reduction does not automatically alter the utility demand tariff. Use the demand calculator separately rather than counting the same component twice.
Test a change in the business
Ask what happens if occupancy, production or equipment differs from the assumed year. Read volume tolerances, minimums, assignment and site-closure terms. Identify quote validity, authorized signer, broker compensation and notice requirements. A proposed operating change must also meet safety, quality and comfort requirements.
For hotel operations, the decision record should connect the usage assumptions with occupancy changes, comfort standards and event loads. Record which assumptions are known, estimated or still awaiting records. A supplier pricing an old profile cannot be assumed to have accepted a new operating plan.
Verify an actual implementation
Retain the offer, comparison and executed agreement. Confirm enrollment and check the first invoice for the right meter, dates, units, product and fees. Explain differences in usage and billing periods before describing a lower invoice as a saving. This example makes no claim about what a real account would achieve.
Read the hotel operating guide, use the renewal planner and review the procurement playbook. Initial inquiries do not require account documents or receive calculator figures.
Context sources
EIA electricity cost components and EIA gas pricing explain broad price context. The numerical inputs and arithmetic here are independently constructed and are not attributed to those agencies as observed results.
Worked example: occupancy changes the interpretation of total energy
Invented monthly operating figures: a hotel uses 60,000 kWh while selling 3,000 occupied room-nights, or 20 kWh per occupied room-night. Another period uses 66,000 kWh for 3,600 room-nights, or approximately 18.33 kWh per occupied room-night. Total use rose by 10%, while the simple occupied-room ratio fell by approximately 8.33%.
Neither measure alone proves efficiency. Lobby, kitchen, pool, ventilation, laundry and vacant-room loads do not all vary directly with rooms sold. Weather, event business and outsourced laundry can also change the comparison. Keep a whole-property metric and an operating explanation rather than treating the ratio as an automatic adjustment formula.
For a proposed project, identify the equipment boundary and record whether occupancy or guest-service requirements changed. A supplier price comparison can use the documented forecast, but a claimed operational result needs a defensible baseline. Avoid counting higher occupancy's effect as a savings achievement or assuming that lower cost per room means the electric bill must fall.
