Swansea Bay tidal lagoon plans unveiled

Details of a proposed £650m scheme to build a tidal lagoon in Swansea Bay, Wales, have been released. Tidal Lagoon Swansea Bay Ltd, the company behind the project, says the tidal lagoon could generate up to 250-300MW of renewable energy per annum, enough to meet the domestic demand of the city of Swansea.

We believe Swansea Bay has fantastic potential for the first manmade tidal lagoon in the world – Alex Herbert, Head of Planning at Tidal Lagoon Swansea Bay Ltd

The construction phase would see a 10.4km breakwater structure built to the south of Swansea Docks, forming a 11km squared lagoon. The lagoon acts to keep the water level high and then let it out through turbines at which would generate electricity. The company has also highlighted the recreational and sporting benefits a lagoon would offer, as well as an education programme for all ages.

Such technology as proposed in Swansea Bay has, according to The Guardian, the support of Friend of Earth which describes the renewable energy as “clean and effortless energy”.

Tidal Lagoon Swansea Bay Ltd hopes to submit a planning application as early as October this year, with work beginning as early as 2017. Should it be approved the six-mile breakwater structure would take two years to build.

Consultation sessions are due to take place in the Ostreme Centre in Mumbles on the 16th and 17th of April, and at the Princess Royal Theatre in Port Tablot on the 18th of April. The final outcome of the scheme is set to be decided in Westminster by the UK Government.

The scheme comes a month after fresh plans arose for a barrage across the Severn Estuary, covered here by GeoJames.
