Interruption of sales and interruptible/UIOLI :
Curtailment of interruptible transport capacities (including backhaul and UIOLI) and stop of capacity trading on the points/direction which stress the limit.

Locational spread :
Call to the market on the gas stock exchange, with a twofold locational product: the TSOs buy gas downstream of the limit and sell it simultaneously upstream of the limit.

Mutualized restriction :
Partial restriction of firm capacities, pro-rata to the subscribed capacities, mutualized on a superpoint. Only on the side of the limit's management.

Winter storage monitoring :
Indicator for monitoring the filling level of storage facilities located downstream of the network limits. The purpose is to verify the availability in the medium term of a sufficient stock to ensure that congestion management mechanisms are effective if activated.

Small impact work :
Indicator used when maintenance has an impact on the limit but does not give rise to a capacity restriction. The level of impact is limited to a maximum “small maintenance” threshold set by the CRE, except for the South-North limits.
