Free shore power from battery in Port of Rotterdam

Free shore power is available at Maaskade in Rotterdam for large inland vessels that are in a trial with shore power from a battery system. 

Free shore-based power is available at Maaskade in Rotterdam. Particularly, for large inland vessels that participate in a trial with shore-based power from a battery system. 


Dutch green energy supplier Skoon Energy has installed a battery system there on behalf of the Port of Rotterdam Authority. Hence, strengthening the local shore-based power supply for inland shipping.

In the center of Rotterdam, there is a ban on generators for inland navigation that is lying idle. The inland shipping sector can make use of shore-based power there. 

However, some ships need more power than the facilities can provide. The battery supports the shore-based power boxes on the quay by making more power available for the moored ships.

The trial will last until 31 March 2022. Therefore, should show whether the battery system in combination with the local shore-based power box can meet that demand. 

Since 2010, shore-based power boxes for inland shipping have been installed at about 60 locations in the center of Rotterdam. These boxes can supply shore-based power to four to six inland vessels up to a maximum of 40 Ampere.

These days, some larger inland vessels (in CEMT class V and above) require more power. To meet this demand without having to take drastic measures, the port authority has opted for this flexible solution.

63 Ampere

Moreover, the battery, located between the existing shore-based power box and the inland vessel. Thus, the battery will supply the extra power required up to a maximum of 63A. Note that, an inland vessel requires more than 40A

On the contrary, in a case without the battery in between; the fuse would blow and the inland vessel would be without power. In addition, in the old situation, other inland vessels can no longer use this shore-based power connection until things get full repairs. 

Linking the battery system prevents this situation and also makes it possible to provide larger ships with shore-based power. 

Shore-based power is an important part of the energy transition. Ships moored at the quay often run on generators for the energy required on board. 

This involves emissions of, among other things, particulate matter, nitrogen, and CO2. Shore-based power offers the opportunity to reduce these emissions by providing ships with a clean energy source.

In January this year, Skoon Energy delivered the Skoonbox – the world’s first maritime-certified, multipurpose battery container. 

The container will be used to deliver renewable power at Damen yards for applications where diesel generators or ships’ engines are primarily used at present.
