### Executive Summary The Viking Link (GB-DK1) and NSL (GB-NO2) interconnectors are running at maximum capacity as Great Britain imports low-cost hydro and wind power. However, planned maintenance on the Viking Link converter station will temporarily choke 1.4 GW of import headroom, widening the GB-Nordic spread.
