Should Gas Transmission Northwest (GTN) be required to curtail receipts from Williams Gas Pipeline West (NWP) at Stanfield due to operating conditions, allocation of capacity will be based on the priority of the service contract used to receive gas into the GTN system from NWP. It is important to note that many customers use Market Centers at Stanfield and that the priority of Market Center service is below that of Firm and Interruptible Transportation services. Although it is not anticipated that this allocation procedure will be necessary, in the event of a unit outage customers should be aware of this curtailment process.

 

Transportation contract nominations that connect directly to the upstream contract of their suppliers from NWP receive the highest allocation priority. Therefore, in the example below, transaction #1 has priority over transaction #2 during this curtailment process. In-line transfers flowing through Stanfield, whether using market centers or not, are not affected, as illustrated by #3 in the diagram.
