Repowering is the process of upgrading or replacing components of a wind turbine to improve efficiency and capacity. There are two main types of repowering, full and partial. It is estimated that, on average, full repowering can double the generation of capacity in MW and triple the electricity output, because the new turbines produce more power per unit of capacity. A partial repower typically increases energy production by 10 to 30 percent. We’ve seen a lot of repowers across the major OEMs, and primarily, the economic reasons are attractive. But repowering doesn’t only make financial sense, it makes environmental and health, and safety sense too.
