A number of measures are in place to optimise the availability
of Interconnector capacity to the market on a short and medium term
basis. Principal among these is a secondary market in capacity facilitated
by flexible capacity trading arrangements, a suite of standard contracts
and a Bulletin Board on which requirements to buy and sell capacity
can be notified to the market.
Interconnector monitors and reports offers to buy or sell capacity and
on capacity transactions in effect with a view to highlighting capacity
trading opportunities and the overall level of capacity trading activity.
‘Use it or lose it’ (UIOLI) arrangements form an integral
part of the Interruptible Capacity regime in the Interconnector, thereby
providing the opportunity for Shippers to transport additional amounts
of gas, to the extent that certain other Shippers are not exercising
their rights to ship in full. The right to use such Interruptible Capacity
reverts to the original Shipper should that Shipper subsequently require
to use its contracted capacity.
