ORML1938 Morlais Tidal Stream Demonstration Project

Closed 28 Apr 2021

Opened 17 Mar 2021


On 17 September 2019 Menter Môn submitted a marine licence application to NRW for a Tidal Stream Demonstration Project called Morlais.

The project will provide a consented tidal technology demonstration zone, specifically designed for the installation and commercial demonstration of multiple arrays of tidal energy devices up to an installed capacity of 240 Megawatts (up to 620 devices). The offshore development area where proposed installation can be placed covers an area of 35km2 to the west of Anglesey. The project will include communal infrastructure for tidal technology developers which provides a shared route to a local grid connection via nine export cable tails, an onshore landfall substation, and an onshore electrical cable route to a grid connection via a grid connection substation.

We publicly consulted on the information submitted with the application. That consultation started on the 27 November 2019 and ended 8 January 2020. Following the submission of further information we consulted with the public a second time between the 29 July 2020 and the 9 September 2020.

We have produced a Statement where more information on the determination process for the Morlais marine licence application can be found. 

Why we are consulting

In Wales, as the marine licensing authority on behalf of the Welsh Ministers, NRW’s role is to determine Menter Môn’s marine licence application. This covers aspects of the project for works required to be undertaken within the marine environment and tidal areas (area which falls seaward of Mean High Water Springs) and to decide whether to issue a licence with conditions or refuse the application. The steps we follow when deciding whether to grant or refuse a licence are defined by legal requirements.  

On the 19 February 2021 further information was recieved from the applicant and we are now consulting with both expert bodies and the public to seek their views on the submission. A list of documents submitted as part of the further information submission can be seen in the document index below and are available on our public register. On the public register we would advise sorting by date, and using the search function in order to locate a specific document.
