THE PROJECT

Arven is one of the UK’s largest floating wind sites, set to lead industrial-scale deployment. Located about 30 kilometres off Mainland Shetland, Arven has 2.3 GW capacity spanning two sites: a 1.8 GW site in the NE1 area and a 500 MW site to the south.

Named after the Norwegian word for “heritage,” Arven reflects both the long-term potential of offshore wind and Shetland’s Norse roots. The project’s logo features the Norse rune for ‘energy,’ honouring this connection.

2022
In 2022, Crown Estate Scotland awarded Arven Offshore Wind Farm an option agreement through its ScotWind leasing round.

2024
In 2024, the Arven project submitted its Offshore Scoping Report. The grid location was also announced by National Grid.

2025
Arven is scheduled to submit its Onshore Scoping Report in 2025.

2025 – 2027
Submission of Scoping Reports, Environmental Impact Assessment Reports (EIAR), and consent applications.

2028 – 2029 (anticipated)
Decisions on project consents are expected

Early – mid 2030s
Arven Offshore Wind Farm is expected to be operational by the mid 2030s.

PROJECT LOCATION

Arven will be located approximately 30 kilometres from Mainland Shetland, with a water depth of roughly 100 meters—perfect conditions for floating wind technology. In regions where sea depths exceed 60 meters, floating wind is the best solution.

Arven Offshore Wind Farm array areas

Stoura Offshore Wind Farm (being developed by ESB)

Arven-Site-Refresh-14

ARRAY AREAS
This is the main site for offshore energy generation, where turbines will be placed. The exact number of turbines will depend on several factors.

This area will also host offshore substations – platforms that gather the electricity produced and send it to land through underwater cables.

Arven-Site-Refresh-15

OFFSHORE EXPORT CABLE CORRIDOR
This is the area containing the subsea export cables which will transmit the electricity from the array areas to the landfall.

Arven-Site-Refresh-16

LANDFALL
This is the area of a coastline where the offshore export cables come ashore and meet the onshore transmission infrastructure.

Arven-Site-Refresh-17

ONSHORE EXPORT CABLE CORRIDOR AND ONSHORE SUBSTATION
This is the onshore area containing buried transmission cables that will connect the array areas to a new onshore substation.
