Renewable energy company Tidal Lagoon Power has announced that it is looking at sites in West Cumbria and Colwyn Bay to form part of a series of six full-scale tidal lagoon power plants along the UK's West coast.
Tidal Lagoon Power is currently in the planning process to deliver £1bn of tidal lagoon infrastructure off the coast of Cardiff, and a plant at Swansea Bay. The Cardiff project will have 90 turbines with an installed capacity, dependent on final design, of between 1,800MW and 2,800MW, giving an annual output of 4 TWh to 6 TWh.
The lagoon has a design life of 120 years, will generate power for approximately 14 hours each day and could be powered on in 2022.
Tidal Lagoon Power is working with LDA Design on the Swansea Bay site. The plant is due to receive a planning decision by June 2015.
The four additional sites currently in the early feasibility and engagement stages are Newport, West Cumbria, Colwyn Bay and Bridgwater Bay.
Together, the national fleet of six lagoons could meet 8% of the UK's total electricity requirement for 120 years.
Mark Shorrock, chief executive of Tidal Lagoon Power, said: "Full-scale tidal lagoon infrastructure gives the UK an opportunity to generate electricity from our amazing tidal range at a cost comparable to fossil fuel or nuclear generation. We have the best tidal resource in Europe and the second best worldwide. We now have a sustainable way to make the most of this natural advantage."
