Morlais is a grid connected tidal stream energy project located in the Irish Sea just off the west coast of Holy Island, Anglesey, Wales. It is being developed by the social enterprise agency Menter Môn. The site has the potential for up to 240 MW of renewable energy to be harnessed from the tides, using a mixture of seabed mounted and floating tidal energy devices from different companies.

The 35 km2 (14 sq mi) site was designated for tidal energy by The Crown Estate in 2010, as the West Anglesey Demonstration Zone, and has been leased for 45 years.[1][2][3] Consent for the scheme was obtained in December 2021 from Natural Resources Wales. The scheme was awarded £31m from the European Regional Development Fund in March 2022, possibly the last significant project from this fund.[4] Following this, construction started in 2022, with phased installation so that any environmental impacts could be understood.[5]

The first devices to harvest power from the tides are expected to be installed in 2026. Before then, preparatory works including the grid connection are being constructed. Mark Drakeford officially opened the onshore substation in October 2023,[6] noting that "Morlais is a groundbreaking project and a key part of our transition to a low carbon economy".[7]

RSPB Cymru expressed concerns about the scheme's potential impacts on wildlife, including guillemots and razorbills.[8] An environmental impact assessment was completed, with detailed independent studies on various aspects of the project construction, operation, and decommissioning.[9] Environmental surveys are still ongoing, with a monitoring buoy equipped with cameras and other sensors deployed in July 2023,[10] as part of the Marine Characterisation Research Project.[11]
