Ohio: 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 Ohio. 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.

Enbridge Gas Ohio: the program detail behind this decision
Enbridge lists nonresidential Energy Choice Transportation Service separately from large-volume and daily transportation schedules. It also distinguishes Standard Service Offer, Standard Choice Offer and Monthly Retail Rate information. Use the benchmark that actually applies to the account; these labels are not interchangeable. Enbridge Oh Rates.
Apply the evidence to an account file
Resolve ECTS-NR, large-volume or daily transportation category as applicable first. The utility or accepted agent must confirm Supplier participation, annual usage category and return or assignment terms. 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 Ohio 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.
