Where is Swansea Bay tidal lagoon?
Where is Swansea Bay tidal lagoon?
Location and site details. The Swansea Bay Tidal Lagoon will be located off the coast of Swansea in Swansea Bay, South-west Wales, UK. It will be situated at the western end of the Severn Estuary.
Is Swansea Bay tidal lagoon built?
With the exception of a commercial loan from Welsh Government this has been financed privately. Our aim is to start on site in 2020. Construction of the entire project will take four years, with first power generated in year three.
How much energy will the Swansea Bay tidal lagoon produce?
The tidal lagoon proposed for Swansea Bay is estimated to have an annual electricity output of around 0.52 TeraWatt Hours (i.e. 0.52 billion units of energy).
How big is Swansea Bay tidal lagoon?
approximately 9.5km-long
In total, this will form an approximately 9.5km-long, U-shaped, seawall which will impound approximately 11.5km2 of the seabed, foreshore and intertidal area of Swansea Bay.
Where are tidal streams?
A tidal stream is usually stronger nearer to the coast where the sea water is naturally shallower causing the water to speed, than it is farther out in deeper depths. Tidal Stream Generation is very similar in many ways to the principles of wind power generation.
How much will the Swansea tidal lagoon cost?
| Tidal Lagoon Swansea Bay | |
|---|---|
| Construction cost | £1.3 billion (estimate as proposed) |
| Operator(s) | Tidal Lagoon (Swansea Bay) plc |
| Tidal power station | |
| Type | Tidal lagoon |
How do tidal lagoons work?
A tidal lagoon is a power station that generates electricity from the natural rise and fall of the tides. Tidal lagoons work in a similar way to tidal barrages by capturing a large volume of water behind a man-made structure which is then released to drive turbines and generate electricity.
What is the difference between a tidal barrage and a tidal lagoon?
Unlike a barrage, where the structure spans an entire river estuary in a straight line, a tidal lagoon encloses an area of coastline with a high tidal range behind a breakwater, with a footprint carefully designed for the local environment.
Where are the strongest tidal currents?
Norway
Saltstraumen is a small strait with one of the strongest tidal currents in the world. It is located in the municipality of Bodø in Nordland county, Norway.
How do tidal streams generate electricity?
Tidal stream generators use the kinetic energy of moving water to turn a turbine—similar to the way a wind turbine uses wind to create electricity. However, the power available for tidal power generation in a given area can be greater than a wind turbine due to the higher density of water.
What are the disadvantages of tidal power?
Disadvantages of Tidal Energy
- Initial construction cost is very high.
- Formation of silt behind the barrage.
- Effect on animals and plants living near tidal stations.
- Very few suitable sites for constructing barrages.
- Disturbs migration of living creatures in the ocean.
Are there any tidal lagoons?
The first ever tidal lagoon is proposed for Swansea Bay in the Severn Estuary in the Bristol Channel, in the south of Wales (United Kingdom.) The Severn Estuary has the second largest tidal range in the world (after the Bay of Fundy) with a range of 8.5 meters.
Is Swansea’s tidal lagoon project back on?
However in February 2019, the Guardian reported that Swansea tidal lagoon plan has been revived – without the need for government funding. It is reported that Swansea-based Tidal Power plc has several major companies interested in buying the low-carbon electricity generated by the tide flowing through turbines in a concrete wall along Swansea Bay.
What is the first tidal lagoon power plant?
Swansea Bay Tidal Lagoon will be the world’s first tidal lagoon power plant. A tidal lagoon is a ‘U’ shaped breakwater, built out from the coast which has a bank of hydro turbines in it. Water fills up and empties the man-made lagoon as the tides rise and fall.
How can we generate low-carbon electricity from Swansea Bay?

Could tidal lagoon energy replace offshore wind power?
The Government considered intermittency due to the tides and that the Tidal Lagoon Swansea Bay would have had a load factor of 19% compared to around 50% for offshore wind power. However, as the monthly variation is predictable Tidal Lagoon energy could allow reduction in the amount of energy generated by gas-fired power plants.
