Coming of age, what to do with mature wind farms? extend, repower or decommission?
At a time when many nations are expecting an explosion of new leasing rounds to meet the gap left by the phasing out of fossil fuels (and in some jurisdictions, nuclear power), it might seem odd to consider the ‘end of life’ options for wind farms – whether lifetime extension, repowering or decommissioning. However, wind turbines have an operational lifetime of 20-25 years. For the original offshore developments in the North Sea, this may be shorter as technology, fabrication and construction knowledge has developed rapidly over the past 20 years.
