Developer Tidal Lagoon Power has secured a grid connection agreement with the UK’s National Grid for its 3.24GW capacity tidal lagoon planned for Cardiff in South Wales.

The £8bn ($10.6bn) lagoon project, to be constructed between Cardiff and Newport, would be the UK’s largest renewables project. With a potential output of around 5.5TWh of electricity annually the project is claimed to be capable of powering every home in Wales.
