Life Extension Solutions: The Impacts of Uprating and Derating on Wind Turbine Reliability
How can you know the impact of uprating and derating wind turbines?
Today, most OEMs offer uprating packages (GE PowerUp, Vestas PowerPlus, etc.) that allow for existing wind turbines to realize higher annual power production. The impact on reliability through derating or uprating is unknown through industry standard techniques. This has led to well under 20 year life of current wind turbine gearboxes.
