Jenny Snook is content executive at GoContractor with the job of researching the latest health and safety trends in the heavy industry. Thus, proponents should not site turbines within the definite impact zone (05 km) as this could severely impact ECCCs ability to gather critical weather information. In 2021, there was anincrease for turbines installed in the 2.753.5 MW range, while the proportion of turbines at 3.5 MW or larger also increased. In addition to getting taller and bigger, wind turbines have also increased in maximum power rating, or capacity, since the early 2000s. However, offshore wind farms exist in a more demanding natural environment so there are a number of extra hazards. This will only work if they are correctly spaced and are subject to changing wind conditions. Company Number 520978. Wind Turbine Safety and Other Hazards. If the lines are operating at less than 150 volts, no limit is placed on the transmitted power of the system.
