Mooir Vannin
The Isle of Man’s first offshore wind farm
About the project
Ørsted is developing the Mooir Vannin Offshore Wind Farm located in the Isle of Man’s territorial waters.
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, off the coast of Maughold Head. The project will help support the Isle of Man and UK’s jointly shared ambitious renewable energy, net-zero and economic growth targets.
The submission of our application for Marine Infrastructure Consent for the Mooir Vannin Generation Project was accepted by the Council of Ministers of Isle of Man Government in August 2025.
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 over two years of extensive environmental and technical studies, as well as in-depth consultation with statutory stakeholders and the public. Following acceptance of the application for examination by the Council of Ministers in August 2025, there is now 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 National Grid at Penwortham in Lancashire and the Douglas area in the Isle of Man. Further information on the work to connect the wind farm to the UK can be found here at www.eastirishseatransmissionproject.co.uk.

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:
