Port of Kiel as pioneer in the supply of onshore power
29 May 2024
The Port of Kiel in Germany inaugurated two onshore power supply (OPS) plants at the Ostuferhafen, featuring both 50/60 Hertz (Hz) and 50 Hz systems for cruise ships and ferries. The Port of Kiel prioritised expanding its OPS infrastructure to reduce CO2 and air pollutant emissions from ships during layovers. The first OPS plant opened at Norwaykai in 2019, with a capacity of 4.5 (Megavolt Amperes (MVA), 50 Hz, 10 kilovolt (kV). Subsequently, a combined plant opened in 2021 at Ostseekai (16 MVA, 50/60 Hz, 6.6/11kV) for cruise ships and at Schwedenkai (5 MVA, 50/60 Hz, 6.6/11kV) for ferries.
The construction project at Ostuferhafen, involves the installation of two onshore power plants capable of simultaneously supplying up to three seagoing vessels. The first system is designed to provide power to a ferry and a cruise ship, connecting four berths at Ostuferhafen. It has a capacity of 16 MVA and can accommodate cruise ships and ferries with frequencies of 50 or 60 Hz and voltages of 6.6 kV or 11 kV. The second system, operating at 50 Hz, is specifically for Roll-on/Roll-off (RoRo) vessels and serves two berths with voltages of 6.6 kV or 11 kV, with a maximum output of 5 MVA. This initiative positions the Port of Kiel as an international pioneer.
