Tidal Power: River Severn

Volume 476: debated on Monday 2 June 2008

To ask the Secretary of State for Business, Enterprise and Regulatory Reform what the reasons were for not considering tidal stream as one of the options to be evaluated by the Severn Tidal Power Feasibility Study. (207455)

The feasibility study focuses on tidal range power generation because the key resource of the Severn estuary is its tidal rangeā€”it has the second highest tides in the world (up to 14 metres) and around 90 per cent. of total UK practical tidal range resource. Whereas, as the Sustainable Development Commission's recent study confirms (Turning the Tide, published October 2007) the tidal stream resource of the Severn estuary is much smaller and represents a minor part of the total potential of UK waters.

The feasibility study is however considering proposals for tidal stream development where this is in combination with tidal range development.
