Welcome to Tidal Lagoon Cardiff’s website.

On this site, you’ll be able to keep up to date with our project to harness natural power from the rise of fall of the tides in the Severn Estuary.

Our proposals are at an early stage. So far we’ve requested a Scoping Opinion for the project from the Planning Inspectorate and will continue to develop our proposals in conjunction with stakeholders, independent experts and the public. You can access our March 2015 Scoping Report here.

We aim to deliver:

  • The UK's first full-scale energy-generating lagoon, with between 1,800MW and 2,800MW installed capacity and an annual output of between 4 TWh and 6 TWh - enough to power all Welsh homes
  • Clean, renewable and entirely predictable power for 120 years
  • A real contribution to the local economy and natural environment
  • Conservation, restocking and biodiversity programmes
  • Improved coastal flood protection in the region

Stay in touch

We will keep local people, their representatives and the wider public up to date with our proposals. For more information on our project, please contact us at cardiff@tidallagoonpower.com or register for updates here.

Tidal Lagoon Cardiff is Tidal Lagoon Power's second project site. For more information on the first site in Swansea Bay, please visit Tidal Lagoon Swansea Bay.
