What is Morlais?

Morlais is a Menter Môn project which aims to benefit local communities, the economy and help tackle climate change by using renewable energy to generate clean low carbon electricity.

The Morlais project manages a 35 km2 area of seabed off the coast of Holy Island, Anglesey and has the potential to put Ynys Môn on the map in terms of tidal stream energy.

The first stage of the project has focussed on securing consent. Community and stakeholder consultation and engagement has been a key part of this process. The consent application was submitted in the autumn of 2019 and a decision is expected by Welsh Ministers during the second half of 2021.

Subject to achieving consent and approval, the second stage will put the necessary infrastructure in place for developers of tidal stream energy converters to deploy their technology in the zone. Implementation will be phased which means devices will be installed gradually and on a small scale to begin with to ensure that the development does not negatively impact marine wildlife.

About Morlais

  • Morlais will provide the infrastructure for developers of tidal energy converters to deploy their tidal devices on a commercial scale.
  • There will be a very controlled phased deployment, with the first turbines being carefully and extensively monitored – only when it is confirmed that there are no negative impacts will further devices be installed.
  • Morlais has the potential to generate up to 240 MW of electricity.
  • The electricity will be transmitted from the Morlais site to the National Grid.
  • Depending on the types of tidal devices used, some may be visible above the sea surface and others will be fully submerged and hidden from view.
  • Any moving turbine parts or rotors will be below the sea surface.
  • For safety purposes there will be some navigation markers showing the location of the devices.
  • Any devices on the surface will have lights similar to the navigation lights on small boats.
  • Electricity will be brought to a substation on shore via a maximum of 9 sub-sea cables.
  • Electricity will be exported from this landfall substation to the existing electricity network via buried cables to grid substation.

How will Morlais Benefit Local Communities?

  • Morlais has the potential to create around 100 well paid jobs in the first ten years
  • Help tackle climate change by generating clean electricity from renewable energy
  • Improve local skills with apprenticeships and training opportunities
  • Work with developers for guaranteed maximum local spend
  • Create new supply chain opportunities for local business during construction and operation
  • Menter Môn will support local businesses to secure contracts
  • All profits will be reinvested locally through a new community benefit fund and through Menter Môn environmental and community projects
