Tidal Lagoon Swansea Bay

Welcome to the Swansea Bay

The proposed Swansea Bay tidal lagoon is the world’s first tidal lagoon based power plant, capable of generating enough electricity for 155, 000 homes, approximately 90% of Swansea Bay.

Our first project, the Swansea Bay Tidal Lagoon, will establish a scalable blueprint for our programme. It is capable of generating electricity for 14 hours a day over its 120 year life. This is a significant opportunity for Wales to take the lead in the tidal industry for the UK as we work towards driving a critical change in the UK’s energy mix with low cost, low carbon electricity sources that are sustainable long-term.
