Lord Wigley (PC)

My Lords, I apologise for coming in late. I am here at the behest of the noble Baroness, Lady Finlay, who apologises to the Committee that she cannot be here to speak in support of Amendment 91, proposed by the noble Lord, Lord Alton. I very much support the points that he made. The noble Baroness has asked me to make a brief contribution to the debate. I wholeheartedly agree with the points she has asked me to raise. These relate mainly to the importance of tidal power in both its devices, which we heard analysed a moment ago. Tidal range is one part of the possibility of creating tidal power; tidal stream is the other. Tidal stream has not yet been well developed and that could be something for the future, but tidal range most certainly has been. There is a predictability about it which gives it a tremendous advantage. Tidal range devices use water height. The differential between high and low levels in the Severn, for example, is an enormously important factor. Using the same principles, there are locations suitable for lagoons as well—certainly around the coastline of Wales, in Swansea Bay and up around Anglesey. I understand that the Marine Energy Council recommends reaching a gigawatt of tidal stream capacity by 2035. This would be an enormous contribution. The noble Lord, Lord Alton, spoke about the possibility that 7% of the UK’s electricity needs could come from the Severn Barrage. That would have the advantage of providing very important construction work, which could make a massive contribution to the south-east Wales economy. Given what has happened recently to the steelworks in Port Talbot, those jobs are very much needed. I hope that the Government will look seriously at this. The case for this type of electricity generation is overwhelming. I hope the Government will give it the attention it deserves.
