Enova has support schemes for shore power that include onshore infrastructure and shore power systems in existing vessels. The support is designed to reduce greenhouse gas emissions from shipping.
Use of onshore electricity for ships docking is a priority activity, as part of the electrification of shipping. Allowing the diesel generators to rest will save emissions of both CO2 and NOx. The vessels will therefore contribute less to greenhouse gas emissions and local pollution. The onshore power solutions will also be adapted to charge the batteries onboard the hybrid vessels. By using batteries for propulsion, parts or all of the sailing can be made emission-free. An important contribution from the authorities is to allocate funds through Enova. Enova has 3 different support schemes that provide support for infrastructure, pre-planning and installation of shore power systems in existing vessels.
An investment in a publicly available onshore power plant requires good decision making. There are many actors who will be interested in such a project. Establishing a cost-effective and customer-oriented approach requires good interaction between providers of infrastructure, grid companies, potential customers and the port. In many cases it also makes sense to hire relevant expertise to have considered all aspects of an investment in onshore power plants.
Enova can support such a pre-project and announces the opportunity to apply for funding three times a year. Up to 50% of the cost of a pre-project can be covered.

Establishing onshore power infrastructure is costly, and at the same time it is an important instrument for reducing greenhouse gas emissions. Enova’s support scheme can therefore contribute up to 50% of the costs of such a facility. The requirement from Enova is that the system has a current of minimum 125 amperes and a voltage of 400 volts. At the same time, the plant must also be built according to shore current standards NEK IEC 80005-1: 2019 for high voltage and NEK IEC 80005-3: 2014 for low voltage. Enova has two calls this year for support for onshore power infrastructure.
Installation of shore power system in existing vessels
Today, many ports have installed onshore power infrastructure. Unfortunately, many ships still do not use shore power. This is because, among other things, the lack of necessary equipment on board or the port does not have the ability to deliver the tension the ship requires. Enova has seen this challenge and introduced a support scheme for the installation of shore power systems in existing vessels. In this way, more and more people will be able to use shore power when the ship is in port.

The electrical facilities in the Norwegian shipping fleet have a number of different specifications for voltage and frequency. This makes it difficult and difficult for the ports to know what tensions the various vessels are demanding. Landstrømsforum, which is a collaborative project between NEK and Enova, has implemented a principled decision to clean up this.
400 V AC 50 Hz
440 V AC 60 Hz *
690 V AC 50 Hz
690 V AC 60 Hz *
6.6 kV AC 50 Hz and 60 Hz *
11 kV AC 50 Hz
11 kV AC 60 Hz *
* The online companies are not obligated to supply this voltage
The network companies are not obliged to supply voltage with a frequency other than 50 Hz. If the ship needs 60 Hz frequency, one depends on a frequency converter. Installation of frequency converters is covered by Enova’s support scheme for onshore power systems in existing vessels.
Landstrømsforum is a collaborative project between NEK and Enova to electrify Norwegian shipping. There are currently 130 members in the Landstrømsforum, representing ports, shipowners, authorities, environmental organizations, equipment suppliers and network companies. The forum’s decision is made by consensus.
