Michigan: Prove the available service before requesting a price
Start with EIA: natural gas customer choice and eligibility. The table below links this decision to the represented gas companies in Michigan. It does not establish service or supplier availability for every account.
Authorization is only one gate
A regulator’s supplier approval and a utility’s accepted supplier or agent are different checks. A licensed company may decline a particular volume, credit profile or service class. Obtain written acceptance for the listed accounts.
Return service needs its own answer
Ask what happens if a supply agreement ends or an agent stops performing. Confirm the utility’s return conditions and start date; a supplier cancellation does not itself establish an accepted replacement enrollment.
Michigan utility application
| Gas service company | Classification and accepted enrollment | Primary reference |
|---|---|---|
| DTE Gas | Participating alternative gas supplier, return rules and accepted enrollment | Official program / tariff |
| Consumers Energy | Licensed supplier, utility program participation and volume obligations | Official program / tariff |
DTE Gas: the program detail behind this decision
DTE’s business guidance distinguishes Gas Cost Recovery service from Gas Customer Choice. DTE’s gas territory differs from its electric territory, including gas service in western Michigan. Use the gas-company name and class on the bill rather than applying electricity choice restrictions to gas. Dte Business Gas; Program Michigan.
Apply the evidence to an account file
Resolve DTE Gas class and Gas Customer Choice or transportation eligibility first. The utility or accepted agent must confirm Participating alternative gas supplier, return rules and accepted enrollment. Retain that answer alongside the named accounts before requesting bids.
An enrollment file that can be handed to another reviewer
Build six fields before seeking a signature: legal gas company; commercial rate code; eligible service arrangement; regulator authorization where required; utility-active supplier or agent; and accepted account/start-date confirmation. Attach the source date and the person who answered each unresolved question. A directory entry belongs in the authorization field, not the accepted-enrollment field. If an account remains on bundled utility service, document that result instead of forcing the review to select a supplier.
Turn the review into a calculation
Plan notice and enrollment milestones. The planner uses your calendar-day inputs and does not send notices or confirm a utility enrollment date.
Read the Michigan utility guide for the wider service-company distinctions. Convert billed gas units using the bill’s heat-content factor when moving from volume to energy.
