Given the renewed interest in the Swansea Tidal Lagoon, it is worth republishing a post I published in June 2018. It still seems as valid now as it did then:
This letter appeared in the Telegraph the other day:
Leaving aside the question of HS2, the writer shows a total lack of understanding about Swansea Bay, which is probably due in turn to the wholly amateurish way it has been treated by most of the media.
So, for Tess’ benefit, here are a few basic calculations:
- Cost of lagoon – £1.3bn
- Electricity produced – 532 GWh pa, which is 0.15% of UK generation
- This is enough to supply on average 40,000 homes
- Therefore the cost per household is £32,500
- There are an estimated 107,500 households in Swansea, so the lagoon could not even supply half of the town.
- Even after the capital costs, ongoing costs will be substantial, for instance dredging and maintenance and replacement of turbines.
If Tess thinks that sounds like a good deal, heaven knows what a bad one looks like!
