Vestas says that it can offer spare parts to all turbines it has in service. Many wind-turbine manufacturers and owners now make use of third-party components as well. There has been some reluctance for some grid operators to allow connection to farms using older second-hand turbines, in case they are unreliable, and inefficient and therefore affect the grid’s ability to supply a constant flow of the electricity required. However with a 20-year life span, second-hand turbines can be just as reliable as new ones, and the increase this year of interest in buying, refurbishing, and installing second-hand turbines, indicates that things are changing.
