A Lighthouse Project for Cruise and Port in Kiel: Shore Power Infrastructure Completed

This project is not a quick fix but the result of clever and long-term planning. While many other ports will only have to react to upcoming EU regulations from 2030 onwards, Kiel began to consistently implement its "Blue Port" strategy back in 2019. The success is based on strong collaboration between public funding bodies and private technology companies. The shore power infrastructure was developed in several stages, allowing for early use and continuous improvement.

The project started in 2019 at the Norwaykai, initially supplying ferries. In 2021, the Ostseekai and Schwedenkai followed, enabling cruise ships to use the power. The first to do so was the AIDAsol. In 2023, the network was expanded at the Ostuferhafen to supply even more ships. The now-completed construction at the Ostseekai makes the infrastructure complete. This phased approach allowed for better project control and enabled the port to gain valuable experience.

The port's facilities are technically state-of-the-art. They can operate at different frequencies and voltages, so both European and international ships can be connected without any issues. The technology comes from companies like Siemens AG and Powercon, among others. Special mobile equipment is used to connect the ship to the shore, ensuring a smooth power supply.

The investment of around 50 million euros was made possible by grants from the German federal government, the state of Schleswig-Holstein, and the European Union. This highlights the political importance of shore power. The collaboration between public funders and private partners made this major project a reality.

The use of shore power facilities is steadily increasing. In 2024, almost 70 percent of all cruise ship calls at the quay were supplied with shore power. A total of 24 different cruise ships have already used the facilities. This use not only protects the local environment. By shutting down the ships' diesel generators in port, emissions of CO$_2$, nitrogen oxides, and particulate matter are significantly reduced. This is a key contribution to the port's vision of being climate-neutral by 2030. As early as 2020, more than 6,200 tons of CO$_2$ were saved as a result.

The Port of Kiel's proactive strategy gives it a clear advantage over its competitors. The nearly ten-year head start allows it to position itself as an environmentally friendly port today. This is a strong argument for attracting shipping companies that also have ambitious sustainability goals. The port can now market its services as clean and future-oriented. The Kiel model thus serves as a blueprint for other ports worldwide that also want to become more sustainable.
