The shore power system at the port, also from Siemens, will cover the electricity demand of all ships at the Ostseekai and Schwedenkai with green power while they are berthed.
The cloud-based system measures the energy consumption in the shore power operations building and at the Ostseekai and Schwedenkai connecting points, and store the data in MindSphere, the cloud-based IoT system from Siemens. The operators have access to all relevant electrical values at any time and from anywhere, allowing them to determine consumption, identify faults, avoid downtimes, and plan maintenance routines better.
“With our shore power system, we are playing a pioneering role and making an active contribution to climate protection,” said Dr. Dirk Claus, managing director at the Port of Kiel. “By systematically recording the power data and storing it in the cloud, the system operator can now determine the efficiency of the systems at any time, i.e. how much energy is actually being drawn. This allows to quickly respond to any anomalies if necessary.”
All the data is captured using 7KM PAC series measuring devices, bundled, and transferred to MindSphere via the Powercenter 3000 IoT data platform, and visualized either via the integrated web server or the Sentron ‘powermind’ app.

“Accurate knowledge of energy flows is crucial in order to ensure that operations run smoothly from a technical point of view and are ecologically as well as economically sustainable – whether in industry or infrastructure,” said Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure. “This provides the Port of Kiel with an uncomplicated digital energy data management and makes the operation of its shore power system even more efficient.”
In 2019, 32 different cruise ships called at the Port of Kiel a total of 174 times, bringing about 800,000 passengers to Kiel. The first shore power system was commissioned in May 2019 at Norwegenkai. The second facility, with connecting points at Ostseekai and Schwedenkai, was connected to the grid in February. This has a capacity of 16 megavolt amperes (MVA) and will be able to supply two ships in parallel for the first time.
