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.
Is the Swansea tidal lagoon being built?
The £1.7bn Blue Eden project at Swansea’s waterfront in Wales will feature the 9.5 km long tidal lagoon structure. Depending on planning consent, work on the Blue Eden site is likely to begin by early 2023.
What are the benefits of the Swansea tidal lagoon?
The lagoon offers the prospect of restoring the native Swansea oyster population, a former Swansea industry that provided 500 local jobs and landed 16 million oysters per year at its peak in the late 1800s.
What happened to Swansea Bay tidal lagoon?
Planning consents for the Swansea scheme then ran down in 2020 after backers failed to secure the final documents needed to begin construction. A floating island with space for 10,000 new homes has also previously been put forward as a replacement to the canned project.
How does the tidal lagoon 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.

Has there ever been a tsunami in Swansea?
Historical accounts say that Green Grounds was submerged when a ‘tidal wave’ engulfed many places along the Bristol Channel, from Swansea to Bristol. It is argued that the wave was Britain’s first recorded tsunami, however, others theorise that it was a powerful storm surge – a combination of high tides and winds.
Why does the UK not use tidal power?
Tidal energy has long lurked at the back of the UK’s renewable energy arsenal, outshone by its wind and solar counterparts due in part to early issues with technology readiness and high costs.
What are the advantages and disadvantages of tidal energy?
A highly predictable energy source. High energy density. Operational and maintenance costs are low. An inexhaustible source of energy.
Some of the disadvantages of tidal energy are:
- High tidal power plant construction costs.
- Negative influence on marine life forms.
- Location limits.
- The variable intensity of sea waves.
Does Swansea have an underground?
Stations include the Liberty Stadium, Swansea University, Swansea Marina, Sketty, Mubles Pier, Langland Bay, Swansea castle, The City Gates, Gowerton, Airport, Pontarddulais, Clydach, Botanical Gardens, Singleton Hospital & More.
Why do Swansea fans swim?
In September 1988, after seeing their side win in Swansea, a group of around 30 Cardiff fans were chased into the sea near Swansea Civic Centre by a group of around 50 Swansea fans. Since then, Swansea fans have adopted a “swim away” gesture, in reference to the event.
Who owns the secret Swansea?
Ryan and Lucy Hole

What triggered Swansea riot?
A vigil held for 19-year-old Ethan Powell descended into chaos when a mob began torching cars, vandalising homes and attacking police officers in the Mayhill area of Swansea last year. Police have charged 27 people over a riot that broke out following the death of a teenager in Swansea last year.
How does water get into a lagoon?
They form in areas with small tidal ranges. Coastal lagoons are created as a shallow basin near the shore gradually erodes, and the ocean seeps in between the sandbars or barrier islands. The size and depth of coastal lagoons often depend on sea level.
What are the disadvantages of tidal energy?
Disadvantages of tidal energy
- The cost: building tidal power plants is currently pretty expensive.
- Effects on the environment: tidal power plants aren’t always good for the environment around them, even though the energy they produce is environmentally-friendly.
- Gaps between the tides: tidal power is not constant.
How does a lagoon get water?
Sea water enters the lagoons by percolation through the barriers, or by overtopping them during storms and high spring tides.
How far out does the tide go in Swansea?
At 10.4m Swansea Bay has the second highest tidal range in the world. At each low tide, a large expanse of seashore is uncovered and waiting to be discovered along the 8km long, main sweep of the bay. Out of the 19 main beaches in the county, Swansea Beach is the longest.
How many homes can the Swansea Bay tidal barrage generate enough electricity for?
Plans first emerged for a tidal lagoon in 2013 with promises it would generate enough energy to power 120,000 homes.
How does a tidal barrage work?
The barrage is installed across an inlet of an ocean bay or lagoon that forms a tidal basin. Sluice gates on the barrage control water levels and flow rates to allow the tidal basin to fill on the incoming high tides and to empty through an electricity turbine system on the outgoing ebb tide.
Will Swansea be under water?
That’s according to the most recent study by Climate Central, a non-profit news organisation focused on climate science, which has predicted that huge areas of Cardiff, Newport, Barry, and Swansea would be left underwater according to current levels of sea level rises due to climate change.
Are there sharks in Swansea Bay?
A shark was spotted trapped in a pool on a Welsh beach on Sunday. The shark, believed to be a common smooth-hound, was seen on CaswellBay in Swansea.
