Tidal Lagoon Swansea Bay

At 320MW installed capacity, with first power expected in 2018, Swansea Bay Tidal Lagoon will be the largest marine energy development in the world. Developed by Tidal Lagoon Power Limited, it will have an entirely predictable 495GWh output each year of clean, green electricity and is estimated that it will power 155,000 homes for 120 years – that’s about 11% of Wales’ domestic use.
