Main findings – summary
The survey shows that one numerous ports can offer both shore power and charging in 2021. If the charging system is to stand clear in time it is essential that all relevant ports and grid company as quickly as possible gets investigated development needs and costs.
There is a need for knowledge dissemination and coordination. It is crucial that information from the shipping companies about what kind of electricity and the plug ships should have been finally determined and that this information is available to ports and grid companies. It is also crucial with coordination and sharing experiences between the actors, and presumably to look at how costs can is reduced through standardization and other
cost reduction. We have sorted the coastal ports by where suitable they are on supplying power 2.3 MW power to the coast. We have in this survey first mapped bedtime, and looked for ports bedtime with more than 15 minutes per call.
Then we have found ports like has 2.3 MW of power on or near the quay. We have shared The ports into three groups, end up 60 minutes or more in bedtime, end up with shorter layover 15-60 minutes and ends up lying down 15 minutes. We also looked at which ones grid company that offers flexible tariff, then this will have a lot to say for the power cost.
As you can see from the table, it is a good deal ports that are well placed. Note that category 15-60 min contains some ports that can have shorter stays than 30 minutes in one direction. The coastal vessels need more than 800 kW hotel operations. Excess current will be able to used for battery charging. Some ports will could offer enough power to cover hotel operation and any charge as well, without any major investments in new network.
It has not been mapped how many this applies, but can have importance, especially in a transitional phase. The climate surface of charging is significant, so it is will be significant, possibly in the shorter term, To use this opportunity so many ports can offer a good deal of charging current, without triggering large investments in new transformer and substation. The survey showed great difference in how far the different ports had come in preparations, but also that many end up wanted to deliver land and charging current.
The survey showed many places were missing dialogue between grid company and port. That kind of dialogue Getting started is very important, and the mapping has been very important for dialogue between grid company and port in many places. We also looked at the costs. We see still high costs associated with Effect tariffs in some places can be very high electricity.
The tariff can be in the grid company without discounted flexible (“disconnectable”) tariff become one barrier that can stop projects, though the harbor has electricity and the development of infrastructure gets Enova support. Land-stream projects will be particularly good suitable for flexible discounted tariff when the ships have alternative energy sources on disconnection, and will therefore help to reduce the need for investments in the network. For investment costs and construction contributions are There are also significant variations in those cost estimates and figures we have received. The survey has also looked at what kind of needs the coastal ships have.
It is very important with good dialogue between shipping company and port as well as grid company to ensure that
the right infrastructure is being expanded. It will be difficult important for the future that the shipping company is early with
communicating their needs to the ports, and having dialogue about this.
This gives the following conclusions:
1. Many ports can offer 2300 kW in 2021.
2. Many ports can offer 1200-1400 kW in 2021. This is sufficient for ships to both cover hotel operation and charge, though not at max Charge on all ships.
3. At a number of grid companies the net rent is one barrier as it becomes very high.
4. There is a need for coordination, transfer of competence and dissemination of information between harbor, shipping company and grid company.
5. There will be a significant need
investments in charging and offshore installations in many coastal ports.
