Government review likely to back Swansea Bay tidal lagoon

1.3bn plan is seen as 'pathfinder' for six bigger plants, which could generate more than 10% of UK's electricity

Plans for a pioneering tidal power lagoon in Swansea Bay are expected to be supported by a government-commissioned report this week, potentially unlocking a multibillion-pound series of projects harnessing electricity from the rise and fall of the tide around the UK.

When ministers last year ordered a review to see if the technology could affordably provide green energy to the UK, it was widely seen as a way to kill off an ambitious project at Swansea proposed by Tidal Lagoon Power.
