What is the Swansea tidal lagoon project?
The Swansea Bay Tidal Lagoon (SBTL) will be the world’s first purpose-built tidal energy lagoon. The 320MW pathfinder project aims to provide a scalable blueprint for tidal lagoons, opening up the option of a fleet of larger UK tidal lagoons to generate renewable electricity.
What happened to Swansea tidal lagoon?
Developers behind the Swansea Bay Tidal Lagoon no longer have planning permission to build the project, the UK government has said. But despite that, both UK ministers and Swansea council insisted permission expired at the end of last month. Swansea council said no part of the scheme “may now proceed”.
What are the benefits of a tidal lagoon?
The main advantage of a tidal lagoon is that it has less environmental impact than tidal barrages because they don’t block the entire flow of water into and out of a given area. They can also more easily be combined with intermittent pumps that use renewable energy to raise the level of water within the lagoon higher.

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).
Which country built the first tidal power plant?
France
The world’s first large-scale tidal power plant was the Rance Tidal Power Station in France, which became operational in 1966.
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.
How much energy does a tidal lagoon produce?
Where is the largest tidal power plant?
Sihwa Lake tidal power station
With an output capacity of 254MW, the Sihwa Lake tidal power station located on Lake Sihwa, approximately 4km from the city of Siheung in Gyeonggi Province of South Korea, is the world’s biggest tidal power plant.
What is the future of tidal energy?
The potential energy that could be harvested from tidal movements on a global scale is enormous. It is estimated that around 1 terawatt of exploitable power is stored in the world’s oceans. This would be enough to power 10 billion 100-watt lightbulbs at once.
How does the lagoon in Swansea Bay work?
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 Bay seawall a tourist attraction?
The Swansea Bay Tidal Lagoon is expected to become a major tourist attraction with around 100,000 visitors per year. It will host a variety of leisure, tourism, cultural and marine aquaculture ventures. The lagoon seawall will be fully accessible for exercise, along with extensive public open space including a beach and rock pools.
Who are the investors in Tidal Lagoon Swansea Bay?
One of the investors in Tidal Lagoon Swansea Bay was Good Energy, a firm led by Shorrock’s wife Juliet Davenport. In return, Good Energy took a comprehensive charge over the project’s assets, giving it a uniquely privileged class of shares compared to the other ordinary investors.
What was the load factor of Swansea Bay?
There are different ways to evaluate tidal energy output. 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.
