You report (Tidal lagoon power is ‘reliable and affordable’, 13 January) that the Swansea Bay scheme “would be the first of its kind in the world”. In France, the Rance estuary plant has been operating since 1966. In Canada, in the Bay of Fundy, which has the highest tides in the world, the plant at Annapolis Royal has been operating since being opened by Prince Charles in 1984. However, the French have no firm plans for more such plants and the Canadians have abandoned them altogether. In Canada, a major consideration has been the devastating impact on fish stocks.
It seems to me that the major objective of the proposal might be to extract taxpayer funding for no useful purpose, and the government needs to study the proposals very carefully to ensure we do not end up with a number of very large white elephants in the Severn estuary.
