Kiel Intros Germany's Largest Shore Power System

The Port of Kiel commissioned Siemens to build Germany's largest shore power system to date which is capable of supplying two ships simultaneously.

With a power of 16 megavolt amperes (MVA), the Siharbor solution will supply two ships simultaneously with certified eco-power, for the first time. This will reduce annual CO2 emissions by more than 8,000 tons.

The system is expected to go into test operation within the 2020 cruise ship season. Maritime shipping plays a special role in Kiel. The port is the point of departure for cruises and has ferry connections to the Baltic states and Scandinavia. 32 different cruise ships stopped in 174 times at the port facilities in 2018.

"By building this new shore power system we will actively support the climate objectives of the Schleswig-Holstein state capital," said Dr. Dirk Claus, managing director with the Port of Kiel.

Claus added: "The shore connection system lets us draw electricity from renewable energy sources, both for cruise ships docked at the Ostseekai and for the ferry at the Schwedenkai. We thereby take on a leading role and consistently implement our Blue Port concept for a sustainable and future-oriented development of the Port of Kiel. In future 60 percent of the energy demand required by the ships entering Kiel will be covered by climate-friendly shore power as diesel generators will be shut down while they are berthed."

The Siemens installation consists of one substation with four Geafol cast resin transformers, four air-insulated medium-voltage Nxair switchgears as well as one 16-MVA frequency converter.

The cast resin transformers with a rated power of six and 16 MVA are especially suited for challenging environmental conditions, such as the salty air present at the port. The switchgear is robust and has a compact design, making it suitable for this application.

With its "Master Plan for 100% Climate Protection", the City of Kiel has an ambitious roadmap to be CO2-neutral by 2050. The new shore power system at the Port of Kiel aims to support this goal with the reduction in CO2 emissions it will bring.

The shoreside power supply installed by Siemens in the spring of 2019 at the Norwegenkai has already started operations. To date, it has helped slash CO2 emissions by about 1,000 tons.
