Offshore met mast installation is expensive and time-consuming, so remote sensing devices are increasingly employed as a cheaper and quicker alternative. However, turbulence intensity measurements from remote sensing cannot be directly related to measurements provided by cup anemometers. Turbulence intensity is a key input to wake models and a significant driver of turbine loading, and therefore impacts wind farm energy yield, turbine selection, and capital expenditure. This study investigates the variation and drivers of turbulence intensity around the British Isles, to determine whether on-site turbulence intensity measurements are required for proposed offshore wind farms. The work has been carried out by Prevailing for the Carbon Trust's Offshore Wind Accelerator and Mainstream Renewable Power.
