Natural gas offer worked example: manufacturer operations
An explicitly hypothetical gas 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 250,000 therms, identical start and end dates, and the same included cost components. Offer A has a flat rate of $0.62 per therm and no monthly supplier fee. Offer B has a flat rate of $0.6 per unit and $65 each month in supplier fees.
| Entered component | Offer A | Offer B |
|---|---|---|
| Annual commodity amount | $155,000 | $150,000 |
| Annual recurring supplier fees | $0 | $780 |
| Modeled annual supply total | $155,000 | $150,780 |
The difference is $4,220 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 a gas offer, verify therm versus Mcf pricing, the bill heat-content basis, location and transport components, and who manages balancing or nominations. Do not treat a commodity-only price as a delivered total.
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: batch intensity is not the same as total fuel reduction
Hypothetical production figures: 20 batches use 40 therms each, or 800 therms. A different operating period makes 25 batches at 36 therms each, or 900 therms. Fuel per batch falls by 10%, while total fuel rises by 12.5%.
The result does not prove a process improvement. Batch size, product mix, moisture, starting temperature, quality requirements and rework can change fuel needs. Use a consistent output denominator and record which loads are fixed across the run. A smaller batch should not automatically be treated as equivalent output.
For a real thermal project, define useful output, metering boundary, operating conditions and baseline adjustment before implementation. Keep the gas-price effect separate from consumption and output effects. If a supplier contract has a volume band, the changed production plan also needs a contractual review rather than assuming a lower unit intensity eliminates quantity risk.
DOE steam-system resources provides a system-review starting point. The batch calculation is independently constructed; it describes no customer, equipment test, industry norm or achieved saving.
