Build an account-specific enrollment record
This checklist is an implementation exhibit for the broader supplier-choice guide. It does not determine eligibility from a business address.
Company-specific evidence to obtain
| Gas company | Account classification | Written service answer | Reference |
|---|---|---|---|
| Nicor Gas | The named delivery company and its eligible small-commercial service class | Supplier registration, cancellation terms and return-to-utility conditions | Utility/program evidence |
| Ameren Illinois | Ameren gas rate zone, service class and any separately qualified transportation schedule | Written transportation qualification before treating a marketer proposal as executable | Utility/program evidence |
| Peoples Gas | The named delivery company and its eligible small-commercial service class | Supplier registration, cancellation terms and return-to-utility conditions | Utility/program evidence |
| North Shore Gas | The named delivery company and its eligible small-commercial service class | Supplier registration, cancellation terms and return-to-utility conditions | Utility/program evidence |
| MidAmerican Energy | Operating state and MidAmerican commercial gas rate | State tariff, supplier/transport availability and the accepted service agreement | Utility/program evidence |
Keep four approvals separate
Document who may release account data, who may negotiate, who may sign, and who verifies utility acceptance. A letter of authorization for information access should not silently become permission to execute a supply agreement.
The enrollment file should identify accepted meters, authorized supplier, service start, old-agreement notice evidence and any unresolved exception. A signed proposal can remain subject to credit or utility processing; do not treat it alone as proof that service has changed.
Close the loop after implementation
Compare the first supply and delivery invoices with the accepted service period and written price formula. Flag estimated reads, prorated fees and late enrollment separately. Retain the correction and resolution instead of replacing the original evidence.
Use the renewal planner for reminders only. Keep required notices and accepted enrollment confirmations in the account file.
