Maryland: 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 Maryland. 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.

Baltimore Gas and Electric: the program detail behind this decision
Maryland’s official gas-choice resource separates utility delivery from licensed supply and requires customer authorization for a switch. Compare a commercial offer with the appropriate utility supply component. An electric provider, a residential rate display or a PSC license alone does not establish enrollment for this gas meter. Program Maryland.
Apply the evidence to an account file
Match a proposed or approved change to Gas distributor, commercial rate class and utility-registered supplier. Reopen the effective company reference and confirm Customer authorization, accepted enrollment and first-bill reconciliation 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.
