Abstract

Lashy Sound is a small channel in Orkney, Scotland,where a tidal stream energy development is planned. This study uses numerical modelling to investigate the energy resource of the Sound and the effects on the flow of removing this power. Anew 3D regional-scale hydrodynamic model of the area was built using the MIKE software and was used to study Lashy Sound. A standard momentum sink approach was used to represent tidal energy converters. It is estimated that the maximum possible yield from this channel from the M2 tidal constituent alone is 23 MW mean and 61 MW peak power, although this would require anunrealistic and uneconomic arrangement of tidal turbines. The 30 MW capacity that is planned is predicted to be feasible, and the environmental effects of both large and small arrays are discussed.
