Jeffreys Bay Wind Farm has a 20 year lease agreement with Eskom, should the project then need to be decommissioned, it will be done in accordance with the environmental authority’s stipulations.
Typically they will require all visible traces of the wind farm to be removed. This takes care of the turbines. Access roads can be removed, although it may be best to leave them for public or private usage. The concrete bases can also be removed, but it is often better to leave them under the ground, as this causes fewer disturbances. If the turbine bases are left they would be covered with stone or other indigenous material, and the site returned as closely as practicable to its original state. Wind energy technology is essentially reversible, and compared to the problems associated with decommissioning a nuclear power station, or a coal or gas fired plant, decommissioning a wind farm is straight forward and simple.
