F24-S Service

Do you want firm injection or withdrawal rights post Timely nomination cycle?  How about firm all day on 13 nomination cycles?

Our F24-S service enables you to access firm injections and withdrawals all day using any of our 13 nominations cycles. This service offers exceptional flexibility to customers who have varying storage injection or withdrawal needs throughout the gas day, or to those who enter into transactions after the Timely nomination cycle.

Service Highlights

  • Enhancement to a new or existing firm storage service
  • Firm daily service - on all five NAESB nomination cycles plus additional eight nomination cycles
  • This service transforms the firm injections and/or firm withdrawal parameters contained in the underlying storage contract into a "firm all day" service
  • Overrun applies only to the underlying storage contract injections/withdrawals
  • Quantity of gas injected or withdrawn in any hour cannot exceed the total daily contracted quantity divided by 20
    • Example:
      • Daily firm withdrawal demand = 50,000 GJ/d
      • Hourly contract demand is 2,500 GJ/h (50,000 GJ/d / 20 hours)
      • Total flow at ID2 nomination cycle (12 hours remaining in gas day) cannot exceed 30,000 GJ (2,500 GJ/h x 12 hours)
  • Quantity of gas injected and withdrawn over entire gas day cannot exceed total daily contracted quantity
  • During the gas day, the time between nomination deadline and effective flow of gas is approximately two hours
