Ports of Stockholm: New project combines onshore power and microgrid technology

Sweden’s Ports of Stockholm and its partners have decided to launch a project that combines onshore power supply (OPS) and microgrid technology.

The project, called “Innovative Microgrid Design for Sustainable Onshore Power Supply: Port of Stockholm case study”, runs between 2024 and 2027. The system demonstration is taking place in the Port of Kapellskär and is part of a long-term strategy to create sustainable port environments.

As explained, the initiative aims to reduce emissions, improve energy efficiency and increase port capacity to meet future demands for sustainable energy use.

The Swedish Innovation Agency Vinnova funded the project within the System Demonstrator Sustainable Port program, which is led by the University of Skövde in collaboration with Stella Futura and Ilmatar.

By integrating renewable energy and advanced energy management systems, energy efficiency can be improved, emissions reduced and the operational resilience of the port increased. The system demonstration, carried out in the Port of Kapellskär, will show the way for future green port solutions.

Onshore power is a solution that allows ships to connect to the port’s electricity grid while at berth, allowing auxiliary engines to be switched off. This reduces emissions, noise levels and fuel consumption in the port environment.

“We are working strategically to meet EU regulations that require onshore connection for ships by 2030. This places high demands on the electricity grid, especially in Port of Kapellskär where the current capacity is limited. In Kapellskär, the OPS facility already enables environmental benefits today. By integrating microgrids with OPS, we create a robust and sustainable solution that reduces the port’s environmental impact and strengthens our competitiveness,” Staffan Forsell, Chief Strategy and Development Officer at Ports of Stockholm, commented.

To meet current challenges, such as limited grid capacity and increased loads, while optimizing OPS needs, the project will develop a comprehensive microgrid solution that combines solar cell systems, battery energy storage systems (BESS) and an advanced energy management system (EMS). The solution is expected to ensure a reliable power supply, reduce greenhouse gas emissions and strengthen the port’s resilience to disruptions.

“This project is an important step towards greener and more efficient port operations. By using the latest microgrid technology, we are meeting the demands of the future while contributing to sustainable development,” Mostafa Kermani, Senior Lecturer in Electrical Engineering at the University of Skövde, said.

In related news, Ports of Stockholm inaugurated ‘Sweden’s first’ onshore power connection for international cruise ships in September 2024, improving the region’s position as a sustainable cruise traffic destination.

The new onshore power supply facility — said to be one of Europe’s first — was officially put into operation on September 17 when the shipping company TUI Cruises’ brand new methanol-ready vessel Mein Schiff 7 was connected.
