Tidal power for Shetland

Tides

Shetland is a micro-tidal coast, where the influences of swell, wind driven waves and coastal configuration are the main determinants of water levels on the shore. Spring tidal range in the western Shetland islands is limited to 1.5 m and maximum tidal currents on spring tides are generally <0.5ms-1. The influence of the tide is greatest at locations close to sea level where the coincidence of spring tides and storm waves can lead to flooding.
