The Port of Oslo has opened a new on shore power facility in January for ferries operated by DFDS and Stena Line. Diesel powered auxiliary engines onboard can be shut down while the ferries are powered by clean electricity.
From the Vippetangen power station, electric power is supplied to the ferries’ electrical systems. The ferries connect to the grid with help of a cable crane. This crane is equipped with an 11 kV high voltage cable. Shore power saves the ferries about 1,420 tons of fuel annually. Instead, when the ferries are connected to shore power, they annually use up to 6 million kWh.
The Port of Oslo aims to transport more cargo and passengers by sea in future. Each year, nearly 1.3 million passengers travel with DFDS and Stena Line to Denmark. The ships also carry large quantities of goods.
