Gas contract renewal: coordinate notice, transportation and final settlement
Track gas supplier renewal separately from utility service and transportation duties, with an original calendar-day example.
Identify every agreement that continues or ends
A gas account can involve a commodity agreement, utility service and a transportation or balancing arrangement. Ending one agreement does not automatically establish the treatment of the others. Begin with a service map and read each contract's term, renewal and notice provisions.
For a bundled account the map may be simpler, but eligibility and billing still need confirmation. Nicor transportation resources illustrates why some gas services have distinct administrative records. It does not establish a universal notice rule or mean that every business has transportation duties.
Build a gas-specific transition checklist
Record the commodity term, supplier notice requirement, utility enrollment timing, any transportation nomination responsibilities, inventory or imbalance treatment and final billing procedure. Identify who supplies gas during the transition and who receives operational instructions. Ask whether changing a supplier also changes the agent managing nominations.
Read assignment, business-closure and minimum-volume provisions before treating a move or shutdown as automatic cancellation. The answer depends on the actual agreement and applicable rules. A procurement guide cannot determine a customer's legal obligation from the fact that consumption stopped.
Worked example: calendar arithmetic does not interpret delivery rules
Invented clause: a supply term ends March 31, 2027 and requires notice at least 45 calendar days before expiry. Straight subtraction gives February 14, 2027. That date falls on a Sunday.
Do not automatically move it to Monday or Friday. The actual clause may address business days, receipt, time zones or a delivery method with its own timing. A reminder should be early enough for the responsible person to verify and complete the requirement. This example establishes neither a legal deadline for any reader nor the effect of a notice sent on a weekend.
Use the renewal planner to reproduce a calendar-day countdown, then retain the governing clause beside the result. The calendar download is local and does not send a notice to the supplier.
Reconcile the final and first service periods
Keep old and new supplier effective dates, utility confirmation, meter reads, any settled quantity and invoices. A final true-up may concern an earlier period; it is not necessarily evidence that an old supplier is still serving the account. Ask for a period-by-period explanation before labeling a charge duplicate.
Where inventory or imbalance settlement exists, record the quantity, unit, price source, sign and timing. Do not assume that the commodity rate for the last operating month is also the settlement rate. Obtain the agreement's method and track a promised credit until it appears in the ledger.
Sources and limits
Nicor transportation guidance, Atmos nomination instructions and the customer's actual agreements identify the relevant records. The calendar example and transition method are independently constructed. No universal renewal right, tolerance, notice period or savings result is claimed.
