Interruptible Advance Service (IAS)

National Fuel Gas Supply Company’s pipeline network and system storage facilities are situated to provide access to Appalachian shale gas production areas as well as pipeline interconnects that access the growing markets in Canada and the Mid-Atlantic regions. Take advantage of our strategic location and commitment to customer service to maximize value and enhance your transportation portfolio.

With our IAS service, shippers can borrow gas for a small fee and return it when prices are favorable and/or when operational conditions allow.

  • This service is a short-term interruptible loan of gas and requires EFT, FT or IT transportation.
  • It is available when NFGSC has excess deliverability from storage.
  • IAS is ideal for avoiding pipeline imbalances; meeting sudden changes in weather or operation; avoiding end-of-month price spikes; and for taking advantage of arbitrage opportunities.
  • Fuel retention is charged on transportation on advance only.
