On 31 May 2024, NRW accepted a Marine Licence application from Mona Offshore Wind Limited for works associated with the construction and maintenance of the transmission assets of the Mona Offshore Windfarm Project located in the East Irish Sea.

The Transmission assets consist of export cables, interconnector cables and substation platforms. The proposed export cables make landfall in Llanddulas, North Wales.

Outside the scope of this Marine Licence application is the Generation Assets (which include the wind turbines) and the onshore export cable corridor which extends from landfall to the onshore substation.

Please be aware that in addition to the Marine Licence application, Mona Offshore Wind Limited has submitted an application for a Development Consent Order (DCO) which is currently being considered by the Planning Inspectorate, the proposed DCO includes a deemed Marine Licence for the Generation Assets.

Further information on the application for a DCO can be found on the Planning Inspectorate’s website. 

The Marine Licence application for the Transmission Asset determination will be running in parallel to that of the DCO. Although there are areas of overlap, both have a separate process.

We publicly consulted on the information submitted in the original application. That consultation ran for 28 days and ended 19 August 2024.

On the 13 November 2024, 13 December 2024 and 22 January 2025 further information was received from the applicant. Below are the lists of documents submitted as part of the further information submission. All documents submitted as part of the application can be seen on our public register.
