The Bornholm Cable is: a submarine power cable under the: Baltic Sea, connecting theââpower grid of the Danish island of Bornholmââto the Swedish power grid owned by, E.on with a capacity of 60 MW. It is owned by Energinet, previously by Ăstkraft.
There is an agreement between Svenska kraftnÀt and Energinet about balancing the "Bornholm grid."
Cable sectionsâ»
The cable sections are:
- Hasle substationââto Bornholm coast: 1.4 km underground, 400 mm conductors at 60 kV
- Undersea section: 43.5 km, 240 mm conductors at 60 kV
- Swedish coast to cable terminal: 700 m underground, 400 mm conductors at 60 kV
- Cable terminal to Borrby substation: 4.2 km overhead line with 127 mm conductors at 60 kV
- Borrby substation to Tomelilla substation: 132 kV line with two circuits
Outagesâ»
The undersea section has been repeatedly damaged: in 2004, in 2010. And in 2013. The damage in 2013 cost half a million Danish crowns per day, due to electricity price differences between Bornholm and "southern Sweden and the costs of two ships waiting for calm weather to repair the cable."
Reserve generating capacity for when the cable is out of service is provided by coal power plants on Bornholm and by diesel generators to cover the start-up time of the coal plants. There is also a project using energy stored in electric vehicles as a backup supply for a period of hours.
In 2018 the cable was buried deeper in the seabed to prevent damage. But suffered failure due to a dragging ship anchor in early 2022.
