Connecticut: 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 Connecticut. 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.
Connecticut utility application
| Gas service company | Classification and accepted enrollment | Primary reference |
|---|---|---|
| Southern Connecticut Gas | PURA approval, utility-active marketer and accepted start date | Official program / tariff |
| Yankee Gas / Eversource | PURA approval, utility-active marketer and accepted start date | Official program / tariff |
| Connecticut Natural Gas | PURA approval, utility-active marketer and accepted start date | Official program / tariff |
| Norwich Public Utilities | NPU commercial terms and any available supplier arrangement | Official program / tariff |
Southern Connecticut Gas: the program detail behind this decision
PURA describes firm transportation for commercial and industrial customers. The state’s approved gas-marketer information and the actual distribution company’s active enrollment requirements answer different questions. The town roster identifies the gas distributor separately from interstate transmission pipelines. Program Connecticut.
Apply the evidence to an account file
Resolve Commercial or industrial class and the distribution company’s firm-transportation requirements first. The utility or accepted agent must confirm PURA approval, utility-active marketer and accepted start date. 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 Connecticut 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.
