How to verify gas program and tariff changes in Michigan

Michigan: Trace a change from filing to the affected account

Start with FERC: interstate and intrastate pipeline responsibilities. The table below links this decision to the represented gas companies in Michigan. It does not establish service or supplier availability for every account.

Keep a tariff change record

Record issuing utility, docket or filing reference, affected schedule, approval status, effective date and the first service period affected. Compare the approved sheet with the account’s actual classification.

Treat branding and enrollment separately

A company acquisition or a renamed program does not by itself establish a new price, automatic contract cancellation or eligibility at another utility. Retain customer notices and confirm the legal company and effective service rules.

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

Match a proposed or approved change to DTE Gas class and Gas Customer Choice or transportation eligibility. Reopen the effective company reference and confirm Participating alternative gas supplier, return rules and accepted enrollment instead of importing a rule from another service company.

A change log with an explicit implementation gate

Use a row for the company, source URL, document type, schedule, status, approval date, effective date, affected accounts and action owner. A proposed sheet can inform a sensitivity scenario while remaining outside the effective budget. After approval, verify the final sheet rather than assuming the requested amount survived. For an ownership change, attach the service notice and identify any separate legacy rate areas. Retain the prior reference for earlier billing periods so corrections can be checked against the right rules.

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.
