Start here
For a Rockford business, start with the delivery utility, customer class and the actual operating pattern. A city name does not establish supplier eligibility or an offered rate. Compare electricity and natural gas separately, with the same usage and written inclusions.
The local decision to work through
What should a Rockford machine shop measure before buying on an average cents-per-kWh figure? This guide uses a hypothetical machine shop decision to organize the review; it does not describe a named customer, claim a local industry concentration or publish a citywide market rate. Adapt the worksheet to the premises, account holder and operating schedule actually involved.
Verify the delivery utility before shopping
Read the distribution utility on a current bill for this premises. If it is ComEd or Ameren Illinois electricity, consult the official choice information and verify the account and product requirements. If it is MidAmerican, another utility, a municipal system or a cooperative, use that provider’s account and tariff guidance rather than assuming the same enrollment process. Do not identify service from the city name alone or confuse a supplier brand with the company that maintains the local wires.
Investigate the machine shop question
For the machine-shop case, obtain interval data and a production log for the highest-demand day. Identify which machines ran together and whether the recorded value is measured peak or tariff-billed demand.
The decision rule for this case
Do not infer savings from nameplate totals alone. Test any staggered-start proposal against interval length, tariff minimums and production constraints before comparing its value with a supply-price change.
| Review step | What to record | Decision it supports |
|---|---|---|
| Confirm authority | Who may act for the Rockford premises and which meters are included. | Prevents an offer from covering the wrong tenant, owner or legal entity. |
| Describe the load | Hours, seasonal changes and any planned change at the machine shop. | Helps distinguish current historical usage from the expected delivery period. |
| Normalize the offers | Identical usage, start dates, term and treatment of fixed/variable costs. | A lower unit rate is meaningful only when the cost scope is comparable. |
| Resolve the contract | Renewal, notice, relocation, quantity and pass-through provisions. | Aligns the agreement with the actual business plan. |
Natural gas needs its own eligibility check
The ICC identifies small-customer gas-choice programs in Nicor Gas, Peoples Gas and North Shore Gas territories. Ameren publishes business transportation requirements separately. Use the gas utility and service class on this location’s bill; electric service does not establish gas eligibility. Compare dollars per therm with the same billed energy quantity and include recurring supplier fees. If transportation is involved, clarify who handles nominations, imbalance, storage and the conversion timetable.
An illustrative way to test the decision
Hypothetical worksheet · not local market data
What should a Rockford machine shop measure before buying on an average cents-per-kWh figure?
Demand reduction with a billing floor
Assume measured demand falls from 100 to 80 kW but a tariff floor keeps billed demand at 90 kW. At an illustrative $12/kW, the modeled immediate reduction is $120, not $240. Replace the floor and price with the account tariff; if billed demand does not change, this component produces no immediate saving.
From worksheet to a defensible next step
Keep the current bill period, utility, operational assumptions and proposed agreement together. Decide whether the issue is price, avoidable usage, peak demand, contract timing or account responsibility. A rate comparison will not fix an incorrect meter scope or a lease conflict; an efficiency change will not explain an unclear renewal clause. Use a review to resolve that specific gap. Do not submit account numbers or documents in the initial form.

Questions to resolve
Does a Rockford listing establish a live rate?
No. This is an educational location guide. Current pricing requires verified service eligibility, load data, delivery timing and a written offer. No citywide business rate or guaranteed saving is asserted.
Can electricity and gas follow different rules here?
Yes. Check each delivery utility and service class independently. Municipal electric service, retail electric choice and gas transportation are different arrangements.
