Tidal Lagoon

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 will power more than 155,000 homes for 120 years – that’s about 11% of Wales’ domestic electricity. Tidal Lagoon Power plans to follow with five full-scale tidal lagoons in UK waters; generating up to 8% of the UK’s electricity requirements from the fleet. Tidal Lagoon view1
