All unused capacity (injection, withdrawal and space) is made available through a variety of supplementary interruptible products that can be purchased for various durations. Interruptible products are offered with a specific ranking of interruption (1 is interrupted last):
1. Supplementary Interruptible Services (SIS)
Offered on a pro-rata basis at seasonally capped prices (as per Schedule F of the SSC); users only pay for total uninterrupted utilisation. Any customer nominations that exceed daily firm rates are automatically classed as SIS.
Offered on a first-come/first-served basis at bilaterally agreed prices. Users pay for total uninterrupted allocation, regardless of usage.
