Port of Oslo: Providing Ferries with Shore Power

Port of Oslo is becoming a zero emission port. That is why the Port of Oslo KF is building and operating a new shore power facility, to be opened 8 th January.

Ferries operated by DFDS and Stena Line will get power here when they are at berth. This enables the ferries to contribute to lower climate emissions and promote development of green technology. The CO2 reduction from this initiative is equivalent to emissions from more than 1300 cars annually.

The sea way is the low emission highway

Maritime transport pollutes less and is more energy efficient than any other mode of transportation. The Port of Oslo aims to transport more cargo and passengers by sea. Each year nearly 1.3 million passengers travel with DFDS and Stena Line to Denmark. The ships also carry large quantities of goods.

This is shore power

From the power station at Vippetangen, electric power goes to the ferries’ electrical systems. The ferries connect seamlessly to the grid with the help of a cable crane. The crane is equipped with an 11 kV high voltage cable. Diesel powered auxiliary engines onboard can be shut down while the ferries are powered by clean electricity. The power requirement of the ferries is about 2-3 MW. That’s almost 60 times more power than today’s fast chargers for electric cars. Shore power saves the ferries about 1,420 tons of fuel annually.
When the ferries are connected to shore power, they annually use between 5 000 000 – 6 000 000 kWh. This corresponds to the annual power consumption of almost 400 Norwegian homes. The shore power station has a cost of aprox 17 Million Nkr.

The Port of Oslo

The port aims to reduce 85 % of the CO2 emission by 2030 (action plan adopted by City Council in Nov 14th 2018). Moving cargo from road to sea transport reduces at least 50 % of both air pollution and carbon emissions. The port is promoting alternative fuels and new technology, building infrastructure for emission free solutions, and building shore power for ships.
