Minesto are developing their Deep Green project off Anglesey with a 10MW array

Tidal Lagoon Swansea Bay


Tidal Lagoon Power are developing the world’s first, man-made, energy-generating lagoon in Swansea Bay


Marine Power Systems Limited

Marine Power Systems (MPS) Ltd. was founded specifically to develop the WaveSub Wave Energy Converter (WEC) – a second generation device that directly addresses the fundamental challenges of extracting wave energy.


Minesto are developing their Deep Green project off the coast of Anglesey with a 10MW array. Deep Green is a unique technology that can operate cost effectively in low velocities.

Pembroke Dock Marine

Pembroke Dock Marine is part of the Swansea Bay City Deal and will develop a world class centre for marine energy development, fabrication, testing and deployment.

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. It is estimated that it will power 155,000 homes for 120 years – that’s about 90% of Swansea Bay.

Ramsey Sound

In December 2015, Tidal Energy Ltd installed a single 400kW DeltaStream unit off the coast of Pembrokeshire at Ramsey Sound for a twelve month demonstration period. The project delivered a fully commissioned grid connected device that proved the technical and operational performance of the Deltastream technology.  World leading and ground breaking research was also carried out on the interactions of seals and harbour porpoise with a tidal turbine.

St David’s Head

Eco2 Ltd, a leading renewable energy development company have a 10MW seabed lease off the St David’s Head peninsula in Pembrokeshire. There is a 10MW agreement for grid with Western Power distribution and 2 years of environmental monitoring relevant to the site.
