North Sea Link - next phases of operations and market developments (Feb 2026)

Following Nord Pool's competitive tender award we would like to outline the next phases of the project to continue operating as North Sea Link’s (NSL) service provider with complete implementation planned by the end of November 2026.

Since 2021, Nord Pool has successfully operated the implicit daily day-ahead auction between Great Britain and Norway. The new agreement secures the next phase of North Sea Link operations for a maximum period of 10 years.

Trading will continue to be integrated into Nord Pool’s auctions in Great Britain and as separate auctions in Norway. This means NSL trading will continue to take place outside the common European electricity market.

Key changes under the new agreement

Day‑ahead auctions – resolution change

In Great Britain, Nord Pool will enable multi-resolution trading in the existing N2EX Day-Ahead Auction, allowing 30-minute and 60-minute MTUs.
In Norway, Nord Pool will enable multi-resolution trading in the existing N2NO2 Day-Ahead Auction, allowing 15-minute, 30-minute and 60-minute MTUs.
Gate Closure Times will remain unchanged for the N2EX and N2NO2 auctions.
NSL- cable resolution will shift to 30-minutes MTU
Go-live is expected during April 2027.

Introduction of Intraday Auctions with NSL Capacity

NSL intraday capacity will be offered with a 30-minutes MTU.
Single-resolution trading will apply in the Intraday Auctions

Note

Nord Pool have developed the new solution taking into consideration the requirement to allow additional power exchanges to access capacity on the NO2 side, though as of today, there is only the one power exchange (Nord Pool) accessing capacity on the NO2 side.
