Indiana: 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 Indiana. 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.

CenterPoint Energy Indiana North: the program detail behind this decision
Indiana North’s gas tariff identifies Indiana Gas Company as the operating company and lists its own service locations and rate schedules. Keep it separate from CenterPoint Indiana South, Ohio and Houston: the common brand does not make the transportation eligibility rules interchangeable. Centerpoint In North Tariff Alternate.
Apply the evidence to an account file
Resolve Indiana North sales or transportation schedule and applicable annual/daily-use category first. The utility or accepted agent must confirm Pool operator, agency agreement, usage qualification and delivery start. 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 Indiana 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.
