The Bornholm Cable is a submarine power cable under the Baltic Sea, connecting the power grid of the Danish island of Bornholm to the Swedish power grid owned by E.on with a capacity of 60 MW. [1] It is owned by Energinet, [2] previously by Östkraft. [3]
There is an agreement between Svenska kraftnät and Energinet about balancing the Bornholm grid. [2]
The cable sections are: [4]
The undersea section has been repeatedly damaged: in 2004, [5] in 2010 [6] and in 2013. [7] [8] [9] 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. [7]
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. [6] There is also a project using energy stored in electric vehicles as a backup supply for a period of hours. [10]
In 2018 the cable was buried deeper in the seabed to prevent damage, [11] but suffered failure due to a dragging ship anchor in early 2022. [12]
