The large battery system of 10 MWh will be charged in just 17 minutes in Rødby. In 2019, Scandlines invested in a 50 kV / 25 MW power cable to Rødbyhavn. This cable has now been extended approximately 1.2 kilometres to the new transformer between ferry berth 2 and 3.

Now Scandlines is investing in a 30 kV / 15 MW power cable including transformer and charging station for the port of Puttgarden.  As of 2025, this will reduce the charging time to just 12 minutes in each port and allow the ferry to cover the 18.5 km between Puttgarden and Rødby in 45 minutes with zero direct emissions.
