Limit repository

List of points upstream and downstream of each limit.
Attention: Superpoints are only used in the event of mutualized restrictions or maintenance. The other mechanisms (interruption of sales, interruptible and UIOLI and locational spread) apply to individual points.

    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. Only on the side of the limit's management.

    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.
