Abstract: Flexible operation across a wide range of operating conditions is required to maximise the contribution of tidal turbine arrays to the future energy mix. This study establishes a basin efficiency range of a small array of horizontal axis turbines between 0.45 and 0.79, with dependency on turbine operating point and flow direction. This range is largely due to variation of array thrust as array power varies by less than 15% for all operating points.
