ABB to upgrade HVDC power transmission linkProjects and Operations // August 10, 2017
ABB has won an order from Baltic Cable AB, a subsidiary of Norway based Statkraft, to upgrade the Baltic Cable high-voltage direct current (HVDC) transmission link.
The link runs beneath the Baltic Sea and connects the electricity grids of Germany and Sweden.
As part of the modernization project, ABB will upgrade the control and protection system of the link, with its latest ABB Ability MACH technology.
The 250km long subsea transmission link has a capacity of 600 megawatts and a voltage of 450 kilovolts (kV) – the highest operating voltage in Germany.
Built in 1994 to enhance the efficiency of power utilization, the link takes advantage of the differing patterns of power generation and consumption in Sweden and Germany, pooling energy resources and facilitating the exchange of electricity.
