St. Charles has a municipal electric service pathway. Confirm the utility on the actual bill before assuming an alternative electricity supplier can enroll the account. Gas, delivery tariffs, demand management and efficiency remain separate questions.
The local decision to work through
How should a St. Charles operator separate municipal electric tariffs from gas procurement choices? This guide uses a hypothetical municipal account 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.
Municipal electricity: a different starting point
City of St. Charles electric utility is the first source for its service area, applicable business rates and account rules. Do not assume the ordinary ComEd/Ameren retail-choice route applies to a municipal electric account. Review the utility’s own customer, demand and energy charges; ask about interval data, efficiency programs and distributed-generation rules if relevant. A natural gas bill may come from a different organization and follows its own program.

Investigate the municipal account question
For the municipal case, open separate electric and gas files with provider, class and applicable instructions. Municipal electricity does not establish gas procurement eligibility.
The decision rule for this case
Use the city electric utility for electric tariff questions and the actual gas provider for gas programs. Do not combine enrollment instructions or assume one agreement covers both.
| Review step | What to record | Decision it supports |
|---|---|---|
| Confirm authority | Who may act for the St. Charles 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 municipal account. | 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
How should a St. Charles operator separate municipal electric tariffs from gas procurement choices?
Model use under the applicable service rules
For an illustrative 500-kWh avoidable reduction at an assumed $0.10/kWh, the variable energy effect is $50. Fixed charges remain unless an approved account change removes them. Use the actual utility tariff, and evaluate billed demand separately. This arithmetic does not imply alternative-supplier eligibility.
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 St. Charles 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.
