Shoreside connection
Power supply for vessels.
There are major environmental benefits in providing a power supply to vessels. Carbon dioxide emissions fall significantly and emissions of sulphur dioxide and nitrogen oxide are reduced to a minimum. During a ten-hour port call, diesel operation from one single vessel can generate up to 20 tonnes of carbon dioxide emissions. Furthermore, an onshore power supply creates a quieter port environment and a better work environment onboard the vessel. The Port of Gothenburg has extensive experience of electrical connections and strives actively to encourage more vessels to switch off their engines at the quayside and use onshore power instead.
What is Onshore Power Supply (OPS)?
The European Alternative Fuels Observatory defines OPS as follows:
An Onshore Power Supply enables vessels to shut down their engines while at the quayside as they are connected to an onshore power source. The vessel’s power supply is switched from diesel engines to the onshore power supply without any interruption to services onboard and emissions to the local environment are eliminated. An OPS installation usually requires a building or a shelter containing the necessary technical equipment, which includes switchgear, transformers and frequency converters to adapt the electrical onshore properties to those of the vessel.
Onshore Power Supply (OPS) is also known as Shore Power, Shoreside Electricity (SSE), Alternative Maritime Power (AMP), High-Voltage Shore Connection (HSCV) or Cold Ironing.
Shoreside connections in the Port of Gothenburg.
The RoRo terminal at the Älvsborg Harbour is the first onshore power supply to be established at the Port of Gothenburg. It was set up in 2000 at berths 700 and 712. Since 2011, all of Stena Line’s ferries have been shutting down their engines and instead using the Onshore Power Supply (OPS) to supply the vessels with electricity at the quayside.
OPS in an explosive atmosphere.
To connect power to a tanker at the quayside in the Energy Port, the Gothenburg Port Authority has developed a totally new, globally unique concept that makes it safe, environment-friendly and still cost-efficient. This project has been named Green Cable, and work has been undertaken in close collaboration with several shipping companies on Donsö, national and European ports, classification companies, oil companies in the port and the Swedish Transport Agency.
-1 200 TONNES CO₂
The benefit from supplying power to tankers is a reduction of 1 200 tonnes of CO₂ a year when vessels use green electricity instead of marine diesel.

Offer to shipping companies.
When a shipping company signs an agreement for a power supply, we assume responsibility for providing the onshore installation. If a new installation is needed, we bear that part of the investment.
There are a number of financial incentives for connecting your vessel to the power supply at the Port of Gothenburg. We make no special charge for the electricity – vessels connected to the power supply will instead receive higher points in the indexes on which the environmentally discounted port dues are based. The tax on onshore power has also been heavily discounted in Sweden for a few years now, and is currently at a level of SEK 0.005 per kilowatt hour.
