The Rønne-Rødvig submarine cable is an electrical cable that runs under the Baltic Sea, connecting the Danish island of Bornholm to the Danish mainland. The cable was laid in 2000 and serves as a crucial link for the energy supply of Bornholm, which is not connected to the mainland by any other means.
The cable is approximately 75 kilometers long and has a capacity of 60 MW. It is a high voltage direct current (HVDC) cable, which means that it is capable of transmitting electricity over long distances with minimal losses.
The Rønne-Rødvig submarine cable was installed by Nexans, a French company that specializes in energy transmission cables. It was a challenging project due to the harsh weather conditions and rocky seabed in the area, but it was completed on time and within budget.
Since its installation, the Rønne-Rødvig submarine cable has been a reliable source of power for Bornholm, ensuring that the island's residents and businesses have access to electricity at all times. It is a testament to the engineering expertise and innovation that goes into building complex infrastructure projects like this one.
