The Baltic Cable is a HVDC power line running beneath the Baltic Sea that interconnects the electric power grids of Germany and Sweden.

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 cable on earth, until Basslink came into service in 2006. It is a monopolar HVDC system with a maximum transmission power of 600 megawatts (MW).

The course of the Baltic Cable starts in Germany at the converter station at Lübeck-Herrenwyk, which is on the site of a former coal-fired power station at 53°53′45.8″N 10°48′08.7″E / 53.896056°N 10.802417°E / 53.896056; 10.802417 (Lübeck-Herrenwyk Converter Station). It crosses the river Trave in a channel 6 metres (20 ft) below the bottom of the river and then follows its course as sea cable laid at the Eastern side of this river. After crossing the peninsula at Priwall the cable runs at first parallel to the coast of Mecklenburg-Vorpommern, in order to turn behind north-easterly toward Sweden.
