Subject: QGC Gas Supply Communication to All Suppliers
THIS NOTICE REQUIRES IMMEDIATE ATTENTION – NO RESPONSE TO QGC REQUIRED
To: All Questar Gas (QGC) Transportation Customer Suppliers
Temperatures in our service territory for at least the coming week are currently forecasted to be colder-than-normal. QGC requests that supplies delivered to its system on behalf of transportation customers match actual usage. Please plan accordingly to ensure that supply versus usage stays within the normal +/-5% daily tolerance window. Also, ensure that imbalance payback nominations are in place to accurately reflect your plans to manage contract imbalances.
As provided for in QGC’s Utah and Wyoming Natural Gas Tariffs (Utah tariff section 5.09, and Wyoming tariff section 5.06), QGC will allow +/- 5% of a customer’s volumes delivered from upstream pipelines as a daily imbalance tolerance window. However, QGC may require customers or nominating parties to adjust deliveries or usage that contributes to an aggregate imbalance that would 1) require QGC to take action to maintain system integrity, or 2) reasonably be expected to force QGC to materially alter its prior day’s planned level of a) gas purchases, b) QGC production, or c) storage injections or withdrawals.
Please let me know if you have any questions. Thank you for your attention in this matter.
Subject: QUESTAR GAS - Gas Supply Communication - Customer Interruption/Hold to Scheduled Quantity
The Questar Gas service territory experiencing extreme cold and supply constraints. Firm load demand on the Questar Gas distribution system requires that Questar Gas implement a service interruption for customers with interruptible load.
Supply availability from upstream pipelines to the Questar Gas system is currently limited. Questar Gas is unable to provide additional supplies to make up for any short falls in the amount of gas being provided on behalf of your customers to the Questar Gas system. As a result, even if they have enough firm capacity on the Questar Gas system to cover their usage, they have also been required to limit their usage to not exceed the scheduled quantity being provided to the Questar Gas system for their use.
Their allowable usage for each hour will be equal to the lesser of their firm contract amount divided by 24 or their scheduled quantity divided by 24 for each hour of the interruption. This will be calculated for each hour based on the scheduled quantity available for the applicable hours of the interruption.
