Wales May Get World’s First Tidal Lagoon Power Plant

Mar 20, 2017 at 3:34 PM ET

The world’s first tidal lagoon power plant is planned to start soon in Wales.

The project, which is awaiting final approval from the British government, will use the Atlantic Ocean’s tidal waves to create renewable energy. Its turbines turn when water enters the lagoon, and turn again when it’s released, generating thousands of megawatts of power. That’s enough for more than a 150,000 homes a year.

Six larger lagoons are also planned around the United Kingdom. The estimated cost of the project, including a six-mile sea wall, is $1.6 billion.
