Mooir Vannin

The Isle of Man’s first offshore wind farm

About the project

Ørsted is developing the Mooir Vannin Offshore Wind Farm. 

The name Mooir Vannin comes from the Manx language term for the Irish Sea – and literally translates as the ‘sea of the Isle of Man’. This is fitting as we bring forward these plans to develop the first offshore wind farm in the Isle of Man’s territorial waters, off the coast of Maughold Head.  The project will help support the Isle of Man’s ambitious renewable energy, net-zero and economic growth targets.

We submitted our application for Marine Infrastructure Consent for the Mooir Vannin Generation Project under the Marine Infrastructure Management Act in March 2025. 

Maughold, Isle of Man
The Mooir Vannin Generation Project is part of the overall Mooir Vannin Offshore Wind Farm project and includes the wind farm itself and infrastructure to enable connection to the Island.

Our application followed nearly two years of extensive environmental and technical studies, as well as in-depth consultation with statutory stakeholders and the public. Upon acceptance of the application by the Council of Ministers, there will be opportunity for interested parties to respond as part of the Government’s consultation and subsequent examination process. 

Work is also underway to scope how to connect the Mooir Vannin Offshore Wind Farm to the UK National Grid at Penwortham in Lancashire and the Douglas area in the Isle of Man. Further information will be shared as the project progresses.

Environmental Impact Assessment

 

To support our application for the Mooir Vannin Generation Project we have been working closely with stakeholders across the Isle of Man who have helped us to fully understand the impact of our proposals on the community, economy, and local environment. This was done through an Environmental Impact Assessment which considered how the environment might be impacted during the Construction, Operation, Maintenance and Decommissioning of the Mooir Vannin Generation Project.  This engagement has built on the feedback received during our Community Consultation in summer 2024 and includes a focus on the following areas: 

What the wind farm will look like 

We have carried out a full Visual Impact Assessment of the Mooir Vannin Generation Project. This work includes computer generated images to help understand and visualise what the wind farm could look like from several points along the east coast of the Isle of Man. 

Local environment

We have been working closely with environmental groups on the Isle of Man, including Manx Wildlife Trust, Manx Birdlife and Manx Whale and Dolphin Watch, to understand how the project may impact the local ecology. We have carried out a variety of surveys over a number of years to help us get an accurate picture of the species that could potentially be impacted by our proposals, and how we can mitigate this.

Shipping, navigation and fisheries

Potential impacts on shipping, navigation and fisheries have been assessed, with input from a range of specialists including Isle of Man Steam Packet Company, local fish producers and other shipping and ferry operators in the Irish Sea, as well as the Harbours Division of the Department of Infrastructure. This was followed up by a detailed navigational risk assessment which identified mitigation required to ensure safe navigation and fishing in and around the area.
