Tidal Lagoon Power, the firm behind the £1bn tidal power scheme in Swansea Bay, has announced it is looking at four more potential sites.
Early feasibility and engagement work is now under way on full-scale tidal lagoons at Newport, west Cumbria, Colwyn Bay and Bridgwater Bay.
Once complete, the national fleet of six lagoons, including the Swansea Bay (pictured) and Cardiff Bay schemes, could meet 8 per cent of the UK’s total electricity requirement and last 120 years.
Tidal Lagoon Power has also taken a major step towards the delivery of the Cardiff Tidal Lagoon project after submitting an Environmental Impact Assessment report.
Plans for Tidal Lagoon Cardiff include up to 90 turbines set within a 22km breakwater that will enclose an area of around 70km2 with an average tidal range of 9.21m.
The Western landfall would be approximately 2km from the entrance to Cardiff Bay and the Eastern landfall would be approximately 2km from the mouth of the River Usk.
Site selection and feasibility studies for the project began in 2011, with a dedicated engagement team established in 2013.
The project will have an installed capacity of between 1,800 MW and 2,800 MW, giving an annual output of 4 TWh to 6 TWh.
According to Tidal Lagoon Power, this would be enough low carbon electricity to power every home in Wales throughout the project’s 120-year life.
Mark Shorrock, Chief Executive of Tidal Lagoon Power: “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.
“There is still a long way to go and many environmental surveys to undertake but we will work in partnership with all nature conservation bodies so as to understand, avoid, minimise and mitigate any environmental impacts.”
Prudential will invest £100m in Tidal Lagoon Power’s Swansea Bay project, which became part of the National Infrastructure Plan in December 2014.
A planning decision for the scheme is expected in by the 10th of June 2015.
