Ports of Stockholm makes an important environmental investment

Ports of Stockholm is to establish shore power connections for cruise ships on two locations. The cruise tourism is a highly important source of income for Stockholm and they will, together with other ports in the Baltic Sea, create an international class sustainable cruise destination.

PSW Power & Automation has signed a turnkey contract for two high voltage shore power systems, 8MVA and 16MVA. The delivery includes design and manufacture of the shore power system, high voltage electrical infrastructure and raising the architectural designed buildings on site. The systems will be ready to connect the first cruise vessels in 2023 and 2024.

“Cruise passengers are very important to Stockholm financially and generate over 1,000 jobs in the region. Onshore power connections in Stockholm are part of an important joint environmental investment, together with other Baltic Sea ports, to create an international class sustainable cruise destination,” states City Commissioner responsible for Ports of Stockholm, Joakim Larsson, in their press release.

Shore power with architectural design

The shore power solution is designed as a compact module-based frequency converter system with integrated remote access and monitoring. A cruise ship can consume up to 60.000 liters fuel per day when at shore and emit large amounts of CO2, so establishing shore power will make a major environmental benefit for Stockholm.

PSW Power & Automation is also responsible for the architectural designed buildings. The largest building is a gabion which will emphasize the surroundings and together with lighting it will create a pleasant atmosphere along the promenade. The smallest building is to be made of plaited steel plates which will give the opportunity to see the building`s content.

“The shore power market is an important part of our contribution to the green shift and with this contract, our backlog amounts to more than 300 MNOK related to electrification projects. We are currently working on several exciting potential projects in Europe and as part of our international focus area this contract is of great importance,” says Eirik Sørensen, General Manager of PSW Power & Automation.

The reduction in CO2 emissions, as a result of ferries operating between Stockholm, Helsinki and Tallin connecting to shore power, is estimated to 18.000 tonnes of carbon dioxide annually. Read more about the the collaboration between the three Baltic Sea ports.
