Utility and supplier-choice checkpoint
The utilities below are local service context, not an address-level eligibility guarantee. Confirm the current bill, service address, account holder, and rate class before requesting a change.
| Account | Local utility context | What to verify |
|---|---|---|
| Electricity | ComEd | Meter, tariff/rate code, current supply arrangement, measured and billed demand |
| Natural gas | Nicor Gas | Delivery utility, gas rate class, program eligibility, therms and supplier contract |
Electricity: Eligible ComEd-served business accounts can compare retail electric supply while ComEd continues delivery. Use the ICC’s electric-choice explanation and the account’s ComEd tariff and rate class. Keep supply, delivery demand, and capacity inputs separate.
Natural gas: Nicor lists this community in its service territory. For a Nicor business account, Customer Select is the relevant supplier-choice program. Check current eligibility, supplier fees, billing arrangements, and applicable utility charges and credits.
Supplier selection affects the supply arrangement. It does not replace the delivery utility or its infrastructure and emergency responsibilities. A change in supplier does not guarantee a lower total bill.
Confirm who can authorize a commercial supply contract
For an Evanston shop or office in a larger mixed-use building, confirm whether the electric meter is tenant-held and whether heating is supplied by a central boiler. A utility cost passed through in rent is a different arrangement from a direct ComEd or Nicor account. Request the meter schedule before giving a supplier authorization.
The City of Evanston identifies Nicor Gas for natural gas service, and Nicor’s community list includes Evanston. The relevant gas-choice program for a Nicor account is Customer Select. A reference to “the North Shore” as a geographic area does not establish North Shore Gas as the delivery utility.
A commercial account associated with an institution, campus, or multi-building owner may have its own procurement arrangements. Confirm whether the business can contract independently and whether a community aggregation notice applies to that specific account. Residential advertising and a neighboring business’s enrollment do not settle commercial eligibility.
Account review steps
- Distinguish tenant-held meters from central heat and shared-area accounts.
- Verify Nicor Customer Select terms using the current gas bill.
- Check aggregation or institutional contract status before soliciting offers.
Worked Energy Desk example
Suppose one electric meter costs $2,500 in the entered month and a separate gas meter costs $850. The multi-location planner totals $3,350 per month and displays a $40,200 annualized run rate. That is the sum of the entries multiplied by twelve; seasonal heating or cooling can make actual annual spend different.
Use one row per account, keep unknown contract dates blank, and avoid entering a combined site total again as another meter. Grouping does not establish eligibility for one supplier contract. Add the actual utility name; MidAmerican Energy is available for Quad Cities accounts. Download the inventory before closing the tool. These are illustrative inputs, not local utility rates, supplier quotes, or promised savings.
Build a useful review file
Bring a recent bill for each commodity, twelve months of usage where available, the current signed supplier agreement, and any notice or renewal correspondence. For a demand-billed electric account, add measured peak, billed demand, and available interval data. Note changes to equipment, occupancy, and opening hours rather than treating the last year as an unchanged forecast.
| Record | Why it matters for this account |
|---|---|
| Service address, suite, account and meter | Identifies the actual premises and the party authorized to contract |
| Utility rate code and supply arrangement | Establishes the relevant tariff and comparison baseline |
| Monthly usage and billing days | Shows seasonality and prevents an uneven-period comparison |
| Contract end and written notice terms | Determines the real planning window |
| Cost inclusions and unresolved items | Prevents a headline rate from hiding pass-through exposure |
Use the renewal planner for verified notice terms and the multi-location planner when several meters are involved. If the immediate question is a higher bill, start with the bill change analyzer. The tools run in your browser and do not enroll an account or request a supplier switch. Their assumptions and limits are explained in the calculator methodology.
Decide what to review next
Start with the issue the account evidence reveals: billing reconciliation, demand and operating patterns, a contract deadline, or a complete supply comparison where choice is available. For a municipal electric account, keep the electric task focused on the applicable utility rate and usage; assess gas procurement separately.
When you request an account review, describe the utility, commodity, timing, and the decision you need to make. Keep account and meter identifiers out of public comments or shared examples. An account-specific recommendation requires the actual records, current tariffs, and complete supplier terms.
Practical answers
Questions you may have
Which utilities serve Evanston commercial accounts?
Local utility context is ComEd for electricity and Nicor Gas for gas. Confirm the exact service address, account holder, meter and tariff on current bills; utility boundaries and account arrangements can vary.
Can an Evanston business choose an electricity supplier?
Eligible ComEd-served commercial accounts can choose a retail electric supplier while ComEd continues delivery and outage response. Confirm the account’s rate class, current supply arrangement, and complete supplier terms.
How should the natural gas account be reviewed?
For a Nicor-served business account, Customer Select is the relevant program. Confirm eligibility, supplier fees, utility charges and credits, contract terms, and billing arrangements.
What should Evanston businesses prepare for an account review?
Distinguish tenant-held meters from central heat and shared-area accounts. Verify Nicor Customer Select terms using the current gas bill. Check aggregation or institutional contract status before soliciting offers. Use the linked Energy Desk example as a planning illustration and confirm the account-specific tariff and contract.
Are the example figures actual local rates or guaranteed savings?
No. They are explicitly illustrative calculator inputs. Use your bill’s applicable rates and complete supplier terms. Delivery, tax treatment, minimums, ratchets and other provisions can change the actual result.
