Swansea Bay Tidal Lagoon

Great news! The UK is a step closer to being powered by tidal lagoons as a review commissioned by the Government has come back in favour of this innovative new technology.

The review found that tidal lagoons have a vital role to play in powering our homes and businesses.

Former energy minister, Charles Hendry carried out the review and, as part of it, went to visit South Wales to hear about plans for Swansea Bay Tidal Lagoon.

Once the first lagoon is generating power in Swansea, a fleet of other projects harnessing electricity from the rise and fall of the tide will be possible at Cardiff, Newport, Colwyn Bay in north Wales, the Cumbrian coast and off Bridgwater Bay Somerset.

The price of generating electricity from tidal lagoons means that we can have a good-value source of power here in the UK for many years to come.

What is a tidal lagoon?

A tidal lagoon is a U-shaped breakwater, which is built out from the coastline and has hydro turbines inside it. Sea water flows into, and empties out of, the man-made lagoon when the tide rises and falls. Electricity is generated as the tide comes in and goes out, four times a day, every day.

It’s a fantastic, pioneering technology and great for Britain.

Why’s it great for Britain?

As we live on an island, tidal lagoons are the perfect solution for harnessing our most reliable and abundant natural asset – the tide. This renewable source is one more step away from relying on fossil fuels and a step towards a truly zero carbon future.


Good Energy was one of the first investors in Swansea Bay Tidal Lagoon and we are planning to use some of the electricity generated for our customers. Once operational, it will provide electricity for more than 155,000 homes for at least 120 years.

What next after the Swansea Bay Tidal Lagoon?

Following Swansea Bay Tidal Lagoon, we can expect more, bigger tidal projects that could provide the UK with up to 12% of its electricity.

Tidal lagoons are a brilliant way for Britain to diversify our energy mix while keeping the lights on; it will also create a whole new industry with thousands of jobs as well.

By kicking off a British tidal lagoon industry we are presenting the world with another awesome low carbon option, and its British know-how that will be called upon should other countries look to take up this option.

Bring on tidal power!
