Update of capacities for Nordic Regional Coupling
The procedure for Nordic regional coupling after a Nordic Decoupling from SDAC have been updated. The update will allow Svenska Kraftnät (Svk) to raise the capacities on Swedish internal and Swedish-Nordic borders before the Nordic regional coupling. Updated capacities will be published to the market at least 30 minutes before the Nordic regional coupling Gate closure time. This updated procedure will only apply if the Nordics gets decoupled from SDAC. The updated procedure will be applied from the 25/5 2023 with delivery day on 26/5 2023.
Svk, together with the Nordic TSOs and NEMOs have updated the Nordic procedures for the Nordic Decoupling from SDAC, leading to a Nordic regional coupling. The update will allow for a greater optimization of the capacities for the Nordic regional coupling leading to an improved social economic welfare. The procedural update will only affect the Nordics in a Nordic decoupling and will not have any impact on other regions or decoupling situation in SDAC.
With the updated procedure, Svk will be able to update the capacities on Swedish internal and Swedish-Nordic borders (see all the borders in the table below) in case of a Nordic decoupling from SDAC. The update could only be performed after the Nordics gets decoupled from SDAC and will be performed before the Nordic regional coupling. An update is optional and not mandatory, if an update is performed the capacities on an updated border could only be raised by Svk (not lowered). Updated capacities will be published on relevant publication tools at least 30 minutes before to the new gate closure time (GCT) of the Nordic Regional Coupling.
If no updated capacities have been published 30 minutes before the new GCT the same capacities published to SDAC will be used in the Nordic regional coupling. If no update is performed, no message will be sent to market participant. Meaning, if no message of an update is received 30 minutes before the new GCT no update has been performed.
The updated procedure is applied from Thursday 25/5 2023 with delivery date on Friday 26/5 2023. It will only be used in case the Nordic Region gets decoupled from SDAC. The procedural change will be applicable as long as the Nordics adapts NTC-domain for the Day ahead market.
For any question regarding the update please contact Svenska kraftnät on SDAC@svk.se.
To demonstrate the updated procedure Market participants are welcome to participate in the SDAC decoupling training session on Thursday 11/5 2023 where the updated procedure will be tested.
