Overrun

In a switch from several long-running System Overrun Limitations implemented during this past cold winter, Northern Natural Gas said late Thursday afternoon it is issuing a System Underrun Limitation for all market areas (ABC, D and E/F), to become effective Saturday.

Usually Northern Natural Gas extends a System Overrun Limitation notice only on a day-by-day basis, but as of Friday it said the SOL for all market-area zones that had begun nearly two weeks earlier would remain in effect through at least Monday (March 3).

Northern Natural Gas withdrew the Critical Day notice that had been posted for Thursday. However, a System Overrun Limitation for all market zones remained in effect through at least Thursday.

Thursday was the third and last day of a System Overrun Limitation notice for all market-area zones on Northern Natural Gas.

Northern Natural Gas did not extend a System Overrun Limitation for all market-area zones beyond Friday, ending it after a two-day run.

Northern Natural Gas declared a System Overrun Limitation for all market-area zones (ABC, D and E/F), effective Thursday.

Effective Wednesday, Northwest is lifting a customer-specific Declared Overrun Entitlement Period for overtakes that was issued Nov. 4 (see Daily GPI, Nov. 5). Thanking customers for their cooperation, Northwest said its Jackson Prairie Storage account “is returning to adequate winter storage levels and Kemmerer’s north throughput flow is being reduced.”

Referring to its shipper advisory issued Thursday (see Daily GPI, Nov. 4), Northwest announced Monday a customer-specific Declared Overrun Entitlement Period. It applies to “individual customers with markets north of the Kemmerer [WY] Compressor who take more than 10% of their scheduled quantities for the day prior to the day a customer-specific entitlement is imposed.” The entitlements will begin as early as Tuesday (Nov. 5) and continue to apply until further notice, Northwest said. It added that over the last 10 days customers had overscheduled Kemmerer Station by about 260,000 dekatherms.
