The Severn Estuary has a spring tidal range approaching 14 m, which is among the highest tides in the world. The Severn Barrage is a proposed tidal power station to be built across the Bristol Channel (Severn Estuary). The most successful tidal range scheme is the La Rance scheme in Brittany, France, which has operated for 45 years and produces the cheapest electricity in Europe . Kate Jennings of the RSPB said: "Once again, plans to build a Severn barrage have been effectively dismissed, described as 'hypothetical' and failing to demonstrate either effective mitigation of. Choose wisely, the right tidal power solution must consider - and understand - the estuary system as a whole. 85,000 migratory and wintering water birds (waders including oystercatchers, curlews, dunlins, ringed plovers etc) depend on the mud-flats which would be lost as a results of construction of the Barrage. • Would require significant transmission reinforcements including new substations and up-rated and additional transmission circuits. A barrage across the Severn estuary was previously explored about a decade ago, but the plans were dropped. It has been proposed that the Severn Tidal Barrage will consist of a ten-mile span across the mouth of the Bristol Channel, effectively joining England and Wales. The River Severn has a tidal range of 14 metres - the second highest in the world - making it perfect for tidal power generation. Its high tidal range, approximately 50 feet (15 m), means that it has been at the centre of discussions in the UK regarding renewable energy.
