The Baltic Cable uses a transmission voltage of 450 kV – the highest operating voltage for energy transmission in Germany. The total project cost was 2 billion SEK (US$280 million), and the link was put into operation in December 1994. With a length of 250 kilometres (160 mi), it was the second longest high voltage undersea cable on earth, until Basslink came into service in 2006.
