Electricity offer worked example: manufacturer operations
An explicitly hypothetical electricity comparison for manufacturer operations: operating assumptions, fee arithmetic and contract limits.
An illustrative manufacturer 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
Record shifts, production mix, process heat and shutdowns before pricing. A new production line can change consumption and peak demand differently. Verify whether an agreement tolerates that change, and keep a demand-management project separate from the supply-price comparison.
Equipment to investigate includes production drives, compressed air and process heat. The main constraints to document are shift changes, shutdowns and planned equipment additions. A useful activity measure may be kWh and fuel per production unit, 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 3,200,000 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 | $294,400 | $288,000 |
| Annual recurring supplier fees | $0 | $780 |
| Modeled annual supply total | $294,400 | $288,780 |
The difference is $5,620 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 manufacturer operations, the decision record should connect the usage assumptions with shift changes, shutdowns and planned equipment additions. 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 manufacturer 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: a startup change matters only if it changes the billed peak
Illustrative startup scenario: three loads each draw 20 kW during an overlapping startup interval. Their combined contribution is 60 kW. A feasible staggered scenario leaves only two overlapping, for 40 kW. The modeled difference in that interval is 20 kW.
At an assumed demand price of $18/kW, a 20 kW reduction in the actual billed determinant would be $360 for that month. But a different production interval might still set the account maximum, or a ratchet could prevent billed demand from falling. The equipment overlap alone does not establish the invoice effect. Use the actual interval data and demand calculator with the governing floor, then reconcile the bill.
Check process sequencing, quality, maintenance and safe restart with the operators. A staggered start can be unacceptable if equipment must run together for process reasons. Preserve output, scrap, shift and downtime records so a lower peak caused by lost production is not described as an efficiency success.
