Glossary

Curtailment – the process of reducing scheduled volumes (a.k.a. allocating reduced capacity) when the TSP determines that scheduled volumes exceed the operationally available capacity of a scheduling group after the scheduled volumes have been scheduled (following the confirmation deadline of the cycle) For example, curtailment will apply if capacity is reduced following the beginning of gas flow and if capacity is reduced following the scheduling of the gas. If capacity is reduced following the confirmation deadline for the Evening Cycle (9 PM) then Curtailment Rules would apply to any required reductions which may be made before gas begins to flow at 9 AM on the flow day. The lowest priority type of service is reduced first.
