Interruptible storage injections, including firm deferred delivery overrun, may be allocated. Firm storage injections will not be impacted. The Storage Nomination Guidance on Northern's At a Glance web page provides a daily indication of the direction and likelihood of storage allocations. Northern will be closely monitoring aggregate daily shipper imbalances and may be required to allocate underperforming delivery points in order to maintain adequate supply/market balance and call an SUL should shipper daily imbalances dictate such. If you have any questions, please call your customer service or marketing representative.
