A £12bn scheme to build a series of tidal energy plants in Britain will be kickstarted on Friday as a planning application is submitted for the world’s largest power-generating lagoon in South Wales.
The promoters want to follow up an initial £850m project for Swansea Bay with four even larger lagoons with a capacity of 7,300MW – enough to meet 10% of the UK’s electricity needs.
It’s easy to see that this is a foul, ghastly and hugely wasteful project:
Tidal Lagoon Power has put in a development consent order under the Planning Act 2008, but must convince the government to provide subsidies of £156 per MW/h – even more than that going to offshore wind farms.
That one number is all you need. The power is simply too damn expensive.
So fuck it.
