SERVICE INFORMATION

• Firm, short notice (15 minutes) intraday balancing service providing a park and loan service at Parkway/Kirkwall
• Submit electronic nominations for up to 96 notice periods for changes to activity at Parkway or Kirkwall (ability to increase or decrease net exports to TCPL)
• Shipper can export to TCPL a total quantity equal to its maximum hourly transportation demand. The source of the export can be flowing transportation gas from Dawn, or a withdrawal from DPBS
  • Example
    • Daily firm transportation contract = 100,000 GJ/d
      • Hourly transportation demand = 5,000 GJ/h (100,000 GJ/d divided by 20)
    • Daily firm storage withdrawals = 100,000 GJ/d
      • Hourly storage contract withdrawal demand is 5,000 GJ/h (100,000 GJ/d divided by 20)
    • Total flowing gas on M12 Dawn to Parkway contract at 11:00am = 2,000 GJ/h
    • Total withdrawal from storage contract (at Dawn) at 11:00 am = 0
    • Maximum DPBS withdrawal available from 11:00 am to 12:00 pm = 3,000 GJ/h (5,000 GJ/h transport limit less 2,000 GJ/h flowing gas)
• Shipper can reduce its exports to TCPL and inject into DPBS
  • Example - use same storage and transportation parameters as above
    • Total flowing gas on M12 to Parkway contract as 11:00 am = 2,000 GJ/h
    • Total injection to storage contract (at Dawn) at 11:00 am = 0GJ/h
    • Maximum DPBS injection available from 11:00 am to 12:00 pm = 2,000 GJ/h (equal to 2,000 GJ/h of flowing gas on transport)
• Hourly DPBS quantity determined as lesser of hourly transport demand and hourly storage withdrawal demand
• Shipper submits an hourly profile which specifies the net deliveries to TCPL for each hour (by 15 minute segment)
• Balance account limits:
  • Maximum Upper limit (storage limit)- plus 3 times Hourly DPBS Quantity
  • Maximum Lower limit (loan limit)- negative 3 times Hourly DPBS Quantity
