In this technique, turbines and their foundation and array cables are replaced by larger units which are spaced at larger distances. This is an alternative technique to continue operation with the same configuration. This technology faces a major challenge due to the rough and corrosive offshore environment. Further, to reduce the cost of repowering wind farms, transmission assets can be retained after some renovation. Retainment of transmission assets lowers the cost of farm by decreasing the energy cost for the repowered phase. This will also reduce the levelized cost of electricity during the entire lifetime of the farm site (IRENA 2016).
