 Abstract

In 1987 a study of small estuaries around the coast of the United Kingdom was undertaken by Binnie & Partners for the Department of Energy. The Wyre was identified as one of the most promising sites for the construction of a small tidal power scheme. The Wyre Estuary is located in Lancashire on the north west coast of England. The estuary fulfils the main requirements for a tidal energy scheme in that it has a high tidal range and a mouth which is relatively narrow in relation to its surface area. The main features of the estuary are as follows : Mean spring tidal range 8.2 m Mean neap tidal range 4.4 m Surface area at +4.0 mOD 7.5 km2 Highest astronomical tide 5.4 mOD 50 year surge tide level 6.3 mOD Mean fresh water flow in river : 6.5 m3/s Length of tidal river 21 km During 1990 a preliminary feasibility study of a tidal energy scheme in the Wyre estuary has been carried out by Binnie & Partners and T.H. Technology, a subsidery of the commercial organisation, Trafalgar House. The scheme was optimised by the utilisation of hydro-dynamic models with the objective to maximise the annual energy output. Two potential barrage sites were examined : - The Pandoro or North site, located 300 m downstream of F1eetwood Docks - The A.B.P. or Centre site, located 100 m upstream of Fleetwood Docks The outcome of these studies were that the North scheme would generate more energy. However, the Centre site was more favourable considering the existing infrastructure. The preferred arrangement for a tidal barrage on this location comprises: - 4 No 6.0 m diameter turbines, peak power 14.96 MW each - 12 channel sluices with radial gates, 9 m wide - 2 fish passes This scheme would generate an annual energy output of 117.2 GWh.
