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 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 and enhanced coastal flood protection in the region

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.  The world’s first electricity-generating tidal lagoons are to be built in six locations across Britain, with at least one already in the planning stage.

Four of them will be located in Wales — in Swansea, Cardiff, Newport and Colwyn Bay — and there’ll be one each in Bridgewater in Somerset and West Cumbria. Tidal Lagoon Power, the firm behind the project, eventually believes that six lagoons could generate eight percent of the UK’s electricity for a cost of £12 billion. The plan is backed by energy secretary Ed Davey.

Here’s how it’ll work in the first location, Swansea Bay. A sea wall eight kilometres long will be built to encircle a large area of water three kilometres out from the coast, isolating it from the sea like a lagoon. Turbines will be set in the wall, which will then generate energy from the difference in water height four times a day as the tide rises and falls. You can explore an interactive 3D model of the lagoon here.
