Tidal Lagoon Swansea Bay is a proposed tidal lagoon power plant, to be constructed in Swansea Bay off the south coast of Wales, United Kingdom. If built it would be the world's first tidal lagoon power plant.[1]
Tidal Lagoon Swansea Bay would operate 14 hours per day with a maximum output of 320MW (nameplate capacity),[2] power around 155,000 Welsh homes[3] and, for a period, sustain over 2,200 construction and manufacturing jobs.[4]
It is also to be constructed to withstand 500-year-storms and to function as a coastline protection against storms and floods.[5]
The project was named as part of the UK government's 2014 National Infrastructure Plan[6] and was granted planning permission by the Department for Energy and Climate Change in June 2015.[1]
Technology
- 9.5km of seawalls, impounding 11.5km2 of the seabed[7]
- 16 bidirectional turbines[7]
- Each turbine is 7.2m in diameter[7]
- Variable speed regulation reduces the harm to fish[8]
Roman concrete has been proposed as a suitable material for constructing the sea walls.[9]
Review
In January 2017, a government-commissioned review, published by Charles Hendry, gave backing to the technology's viability and the concept of tidal generation, but not specifically to this company's commercial proposal.[10][11] The economics of the proposal has been criticised.[12] The effects on fish and wildlife are being assessed.[13]

The scheme's developer Mark Shorrock hopes the project could kick-start a new industry and other developments will follow.
Tidal Lagoon Power in promoting this pathfinder project, proposes it as the first of six tidal lagoon power plants it would like to construct in the United Kingdom, (four in Wales).[14] Claiming they could meet up to 8% of UK electricity demand, or power for around 30% of UK homes. Tidal Lagoon Power is also progressing a number of potential projects overseas.
The scheme's developer claims that to date, approximately £35 million has been spent on project development. With the exception of a commercial loan from Welsh Government this has been financed privately.
