CHAPTER 6 - KEY ISSUES FOR SEA IN THE WIND POWER SUB-SECTOR - 6.1 WHY SEA IS IMPORTANT TO THE WIND POWER SUB-SECTOR

During Construction During the construction of an onshore wind farm noise, and in some circumstances, noise and vibration is generated by: • The building of access roads and hardstanding (hard surfaces); • The erection of wind turbines which includes foundation preparation, tower installation, blade assembly and electrical infrastructure works; • Increased traffic noise from delivery and construct. [...] The problem is likely to be of more significance at high latitudes where the angle of the sun causes longer shadows (i.e., has a large radius of influence) and the magnitude and extent is dependent on the duration, timing, and presence of sensitive receptors18. [...] The degree and nature of the interference will depend on44: • The location of the wind turbine between receiver and transmitter; • Characteristics of the rotor blades; • Signal frequency: • Air traffic control radar; • Air navigation systems, and • The radio wave propagation in the local atmosphere. [...] Public services and infrastructure Communities near wind farms can be affected by the transfer of oversized and abnormal loads carrying large and heavy wind turbine parts (blades, turbine tower sections, nacelles, and transformers) ( Box 6.4: Community development activities funded by the Lake Turkana For the Lake Turkana Wind Power project (one of the largest wind farms in Africa), the Winds of C. [...] Key factors that determine perceptions of wind farms depend on the proximity of turbines to the viewer and the viewing angles of wind turbines.
