Ports of Stockholm, in collaboration with partners, launched an innovative project combining onshore power supply (OPS) with microgrid technology to enhance sustainability.
This initiative aims to cut emissions, boost energy efficiency, and expand port capacity to meet growing demands for sustainable energy.
Funded by the Swedish Innovation Agency Vinnova under the System Demonstrator Sustainable Port program, the project is led by the University of Skövde in partnership with Stella Futura and Ilmatar.
By integrating renewable energy with advanced energy management systems, the initiative seeks to improve efficiency, lower emissions, and enhance the port’s operational resilience. The demonstration at Sweden’s Port of Kapellskär is set to pave the way for future green port solutions.
In addition, OPS allows docked ships to connect to the port’s power grid, enabling the shutdown of auxiliary engines. This reduces emissions, noise, and fuel consumption in port areas.
Staffan Forsell, Chief Strategy and Development Officer at Ports of Stockholm, commented: “We are working strategically to meet EU regulations that require an 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.”
To address challenges like limited grid capacity and rising energy demands while optimizing OPS requirements, the project will develop an integrated microgrid solution. This system will combine solar panels, battery energy storage systems (BESS), and an advanced energy management system (EMS) to ensure reliable power, lower greenhouse gas emissions, and enhance the port’s resilience to disruptions.
Named “Innovative Microgrid Design for Sustainable Onshore Power Supply: Port of Stockholm Case Study,” the project runs from 2024 to 2027. The demonstration, hosted at the Port of Kapellskär, aligns with a broader strategy to create sustainable and efficient port environments.
“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,” stated Mostafa Kermani, Senior Lecturer in Electrical Engineering at the University of Skövde.
