Upstream Pipe Balancing Service (UPBS)

Looking to balance uneven consumption with deliveries of gas supplies at Dawn Hub?

Our Upstream Pipeline Balancing Service (UPBS) enhances your existing storage service allowing you to evenly balance flows arriving at Dawn Hub (including purchased gas supplies, withdrawals from storage, or gas arriving from upstream pipelines) with uneven downstream consumption requirements.

The UPBS allows you to specify the hours of injection and/or withdrawal and ensure that gas supplies closely match consumption requirements on an hourly basis. The UPBS helps you minimize downstream balancing costs.

Service Highlights

  • Quantity of gas injected or withdrawn in any hour cannot exceed the total daily contracted quantity divided by 20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 withdrawal demand is 2,500 GJ/h
      • Quantity of gas injected or withdrawn over entire gas day cannot exceed total daily contracted quantity
    • Example:
      • Daily firm withdrawal demand = 50,000 GJ/d
      • Sum of injections/withdrawals cannot exceed 50,000 GJ/d
  • Customer may nominate UPBS on a firm basis on the timely nomination cycle and on an interruptible basis on each of the next three NAESB nomination cycles. If a shipper contracts for F24-S, the shipper has access to all 13 nomination cycles and the service is firm on each nomination cycle
  • Overrun of UPBS (and underlying storage contract) may be provided. Any overrun of an hourly quantity will be considered as overrun for the entire gas day
