The Åland–Sweden AC cable (commonly referred to locally as "Sverigekabeln") is a 110 kV HVAC subsea interconnector that links the Åland transmission grid to the Swedish mainland. Its primary strategic role is to provide bulk electricity supply and system security for the Åland archipelago by enabling imports from the Swedish...

Project Timeline (5)
2014Onss Commissioned
In 2014, Kraftnät Åland brought the new 110 kV substation Tellholm into service, installing five 110 kV switchgear positions. The substation, located adjacent to the existing Tingsbacka substation, is intended to serve as the new point through which electricity imports from Sweden are routed following grid modernisation, forming a key onshore node for the Åland–Sweden AC interconnector.
2001Major Outage
An unplanned outage occurred on Kraftnät Åland’s 110 kV AC cable link between Sweden and Åland, described as the longest unplanned interruption on this main supply connection, lasting for five hours in 2001 before power delivery was restored.
1973Commercial Operations Full Power
In 1973, Kraftnät Åland commissioned and put into use the first "Sverigekabeln" subsea electricity connection between Åland and Sweden, establishing a dedicated transmission link for importing power to the Åland grid. This initial Sweden cable marked the start of cross-border transmission via this route and later served as the predecessor to the replacement cable installed in 2000.
Date TBDCable Installation Complete
ABB completed installation of the world’s first submarine XLPE AC cable link connecting the Swedish mainland to the Finnish island of Åland, consisting of three 55‑kilometre, 84 kV cables laid on the seabed between Sweden and Åland.
Date TBDConstruction Other
A submarine AC interconnection between the Swedish mainland and the Finnish island of Åland was constructed using XLPE-insulated technology, consisting of three 55 km cables rated at 84 kV and described as the world’s first submarine XLPE cable link on this route between Sweden and Åland.
