Ferry services are connected to onshore power

At Port of Stockholm, Viking Line and Tallink Silja vessels are connected to onshore power. At Port of Nynäshamn Polferries and Destination Gotland vessels are connected. At Port of Kapellskär Finnline's ferry traffic is connected. The archipelago and charter boat services all connect to electricity at the quayside in Stockholm.

The services already connected to onshore power, or are next in line, are also those where onshore power connection has the greatest impact, as those vessels constitute by far the most frequent traffic. The same vessels operate on routes to and from the same ports. A small number of obvious partners are involved and can jointly agree on one solution and funding.

International cruise ships

For international cruise ships calling at Port of Stockholm, it is possible to connect to electricity at berths S167 and S160 at Stadsgården. These are high-voltage facilities according to international standards. Both facilities have been granted EU support and berth S167 has also been granted support from the Swedish Environmental Protection Agency's Climate Step (Klimatklivet).  At least 45 percent of the cruise calls to Ports of Stockholm can now connect to onshore power.

Ports of Stockholm is working from a plan of action to be able to offer more vessels onshore power connection at the quayside. This is a long-term effort, as it requires collaboration and dialogue with the shipping companies and with the other Baltic Sea ports. It also requires a high power output supply and major investment.

Ports of Stockholm’s environmental discounts

For many years Ports of Stockholm has offered environmental discounts to encourage customers to implement environmentally beneficial measures. These incentives focus on reduced emission of air pollutants and reward vessels that have better environmental performance. You will find the discounts in the Ports of Stockholm price lists.

Ports of Stockholm’s jurisdiction

Ports of Stockholm is classed as a public port. This means that the port authorities must in principle allow any vessel that wants to use the port to do so. In other words, Ports of Stockholm cannot insist that vessels connect to onshore power.
